SAP Business Suite powered by SAP HANA Cookbook Introduction 1.1 Migration vs. Greenfield vs. Sidecar To work with SAP Business Suite powered by SAP HANA, customers can either migrate to SAP HANA, build up a new system landscape, or use SAP HANA together with their existing core system. Migration Migration refers to the migration of an existing SAP Business Suite system on any DB to SAP Business Suite powered by SAP HANA. This is normally a project combining the upgrade of the release and the migration of the database. This cookbook focuses primarily on migrating from SAP Business Suite on any DB to SAP Business Suite powered by SAP HANA. It helps to clearly describe the delta between the SAP HANA database and any other database. The migration process consists of specific tasks, for example downtime minimization and SAP HANA code compliance. If you run a Greenfield or Sidecar project, you might find that many of the topics are relevant for you as well however. Greenfield Greenfield denotes the creation of a completely new business system landscape. It is normally a much larger project. Sidecar Sidecar denotes the option of having a dedicated SAP Business Suite powered by SAP HANA system for a selected business process next to your core SAP Business Suite system. SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company. All rights reserved. 5 1.2 Migration Project Phases The migration project to SAP Business Suite powered by SAP HANA basically consists of three phases: Plan, Build, and Run. Plan Based on an assessment of your business processes, you identify and validate the business benefits of SAP Business Suite powered by SAP HANA and build your business case for the migration. Our innovation service supports you with a tailored recommendation of functional and performance improvements. As part of the discovery phase, you may also want to start exploring the tangible value of an SAP Business Suite powered by SAP HANA system through a dedicated system in our SAP HANA Enterprise Cloud (HEC). During this phase, you prepare the project plan by identifying the relevant activities, resources, and tools. You also identify the technical prerequisites necessary for a migration and initiate the procurement process for the required hardware and components. A rich set of tools supports you with the estimation and optimization of the efforts involved in the system upgrade. To follow compliance rules regarding your data and to optimize your database size, consider Information Lifecycle Management. Build If you chose to run SAP HANA yourself in your own landscape, you can practice the upgrade in a sandbox system. Note This step may not be relevant if SAP HANA is run in a hosted and managed environment. After upgrading your development system, you adjust your custom code to ensure that you fully benefit from the performance improvements of SAP HANA. To achieve the highest efficiency, you need to find out which code is really relevant for the migration process. Smart analysis can save you up to 90% of the migration effort. SAP tools provide you with the necessary functionality to focus on the relevant code objects, and a framework for the overall change management. SAP can also provide you with services to execute the actual migration process. After upgrading your quality system, you perform tests. SAP provides you with a new powerful tool set to automate your tests, thereby increasing their quality and largely reducing manual test efforts for future upgrades. To keep downtime as short as possible, Database Migration Option (DMO) of the Software Update Manager was developed to significantly reduce the required downtime, thereby reducing business cost. In future, DMO tools will be able to keep a downtime near to zero. 6 © 2015 SAP SE or an SAP affiliate company. All rights reserved.

Note To understand the documentation, consider the following regarding versions of the SAP Business Suite powered by SAP HANA: SAP originally released business application versions designed for SAP HANA separately from versions designed for traditional databases. Specifically, SAP EhP 06 for SAP ERP 6.0, version for HANA; SAP EhP 2 for CRM 7.0, version for HANA; and EhP 2 for SCM 3.0, version for HANA were designed for SAP HANA. Subsequently, SAP released SAP Business Suite i2013 - Innovation 2013. This includes new enhancement packages for the SAP Business Suite core applications (SAP ERP 6.0 EHP7, SAP CRM 7.0 EHP3, SAP SCM 7.0 EHP3, and SAP SRM 7.0 EHP3). These current enhancement packages are compatible with both traditional certified databases as well as with the SAP HANA database, thus giving more choice to customers to continue to innovate without disruption. Therefore, the naming distinction version for HANA is not necessary for current releases.

All rights reserved. 17 This concept is illustrated in the following figure: In summary, SAP HANA Live provides the following advantages: ● Open - All access to the reporting framework is based on standard mechanisms such as SQL or MDX. No BW modeling or ABAP programming are required. ● Uniform - One approach is chosen for all SAP Business Suite applications, enabling a common reporting approach independent from application boundaries. ● Intuitive - The virtual data model hides the complexity and Customizing dependencies to make data available without the need for detailed knowledge of SAP Business Suite data models. ● Fast - SAP HANA Live for SAP Business Suite features SAP HANA as the underlying computing engine to enable fast analytics on high data volumes. ● Real-time - Since all reporting is executed on primary data or a real-time replication of primary data, there is no need to wait for data warehousing loading jobs to finish. The time frame between recording and reporting is dramatically reduced. Note Despite the benefits of SAP HANA Live, it is important to understand that it is not a substitute for an SAP Enterprise Data Warehouse or SAP Business Warehouse solution. SAP HANA Live allows end users to build operational reports, and offers SAP BusinessObjects tools and a third-party framework with which the data in SAP Business Suite powered by SAP HANA can be accessed. Specific analytic scenarios still require the use of SAP Business Warehouse however. It is a common approach to use the SAP Enterprise Data Warehouse system for historical reporting or reporting of old data. SAP HANA Live is available as a separate package for SAP Business Suite.

Related Information Prerequisites [page 76] 1.3.4 Technical Landscape Planning Technical Landscape Planning involves a variety of activities, such as sizing, deployment and installation options, data volume management, architecture options, and target landscapes. Executive Summary and Key Takeaways ● Technical System Landscape Design provides guidance on the appropriate IT infrastructure for SAP HANA, based on your requirements ● Migration to SAP HANA only involves the switch to another database. Everything else in your landscape will stay the same ● HANA Sizing provides guidelines for a hardware-efficient approach ● Multi-SID HANA installation can provide TCO benefits and greater flexibility of system operations ● DEV and QAS systems can be combined with the MCOS scenario in a single hardware in a multi-tiered landscape Migration Impact on Landscape Switching to SAP HANA does not break the connectivity to other systems, such as third-party systems and central hubs like Portal or PI, or cross-application connections such as CIF and ALE. From a technical point of view, migration to SAP HANA is just a switch to another database. Most other things in your landscape stay as they are. A SAP Business Suite system running on SAP HANA can still connect to and be integrated with other systems and hubs in the same way as a SAP Business Suite system running on any other database. You can still use the same front ends and clients to connect to your system. Even the application servers can be reused as they are, provided they are running on separate servers and not on the database host. SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company. All rights reserved. 27 What will change is the kind of database currently running. SAP HANA has a few operational specifics, for example that it runs on SUSE Linux Enterprise. This concept is illustrated in the graphic below: 28 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction 1.3.4.1 Technical System Landscape Design To design the technical system landscape for SAP HANA, follow the steps described in this topic. SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company. All rights reserved. 29 Context 30 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction To develop and implement the future technical architecture for SAP systems with SAP HANA, proceed as follows: Procedure 1. Define the deployment options either in the data center (on-premise) or using a hosted (cloud) solution. 2. Define the hardware (HW) acquisition requirements either by using Appliance or by following the Tailored Data center integration approach. For Appliance, check partner solutions with customer-specific data center requirements. 3. Define the general technical architecture, i.e. the components required and the sizing for all applications. Map the sizing results to your hardware using either single-node or scale-out HANA appliances. Bear in mind the SAP HANA architecture, for instance the usage of Master Node. 4. Consider implementing a data volume management strategy if the required DB size is very large. If you cannot reduce your uncompressed data below 4 TB, consider implementing the scale-out approach. 5. Decide on the required number of SAP systems to manage software changes (number of systems in a landscape). 6. Deploy different components, MCOD, MCOS, and virtualization options for setting up each system 7. Define a strategy for high availability and disaster recovery. 8. Define a software change management landscape. 1.3.4.2 System Sizing Due to the appliance character of SAP HANA, sizing is easier and at the same time more complicated. It is easier because the choice of hardware configurations are limited at the moment, and SAP offers tools and procedures that help to determine the required hardware for exact requirements. Sizing is more challenging because of data growth and thus careful planning and aggressive housekeeping have a much higher impact on cost of ownership than with traditional RDBMSs. Sizing Principles The most important sizing driver is the memory, and the second most important is the CPU requirement. I/O sizing is also extremely important, but can only be performed during the realization phase. There is also a disk space requirement for persistence and log data, but this sizing is completely dependent on memory and thus fairly straight forward. ● Memory (most important sizing driver) ○ Memory sizing is determined by the data footprint in SAP HANA (business and metadata in column and row stores) ○ Memory is also used by other components, for example SAP HANA caches and the operating system ● CPU ○ To forecast the DB CPU requirement is challenging. This is true for both SAP HANA and AnyDB SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company. All rights reserved. 31 ○ CPU usage is different for SAP HANA than AnyDB ● Disk ○ Disk is required for data persistence and for logging data ○ Sizing formula is independent of whether the system is an OLAP or OLTP system Sizing for New Installations of SAP Business Suite powered by SAP HANA ● Use Quick Sizer for initial sizing and apply the rules in SAP Note 1793345 finding a sizing for SAP Business Suite on SAP HANA : Sizing for Suite on HANA for ● To perform a throughput-based sizing in Quick Sizer with realistic retention times for the business data, use Quick Sizer (Online): https://service.sap.com/quicksizer Table 8: Result in Quick Sizer Sizing Suite on HANA Calculation Factors Estimated database size Input for HANA memory (DB size / compression factor) * temporary memory usage Compression factor: 4 Temporary memory usage: 2 Estimated CPU requirements for the DB server Input for HANA CPU DB SAPS * 4 Estimated database size Input for HANA Disk Space DB size / 2 Estimated CPU requirements for the App server Can be used 1:1 - Estimated memory requirements for the App server Can be used 1:1 - Sizing for SAP Business Suite powered by SAP HANA Migrations Space Needed when Migrating to SAP Business Suite powered by SAP HANA In general you can expect a compression factor (size on current system / size on SAP HANA) of ~4 based on the early pilot customer results, although this can of course vary in every case. ● Use Current Customer System Size for Application server ● Apply SAP Note 1872170 in source system. This SAP Note implements a report to estimate the memory space requirement for the database tables of SAP Business Suite poweredy by SAP HANA systems. The program runs on non-HANA systems.The report output is only an estimation of the memory requirement of SAP HANA. SAP makes no waranties with respect to the accuracy of the report result. The customer is responsible for verifying any output and deciding on whether to implement any of the recommendations made by the report. ○ Analyzes all (or selected) tables on the source system and estimates their size on SAP HANA ○ Uses data sampling 32 © 2015 SAP SE or an SAP affiliate company.

SAP Business Suite powered by SAP HANA Cookbook Introduction ○ Considers distribution of tables to row and column store ○ Considers de-clustering and de-pooling ○ Considers differences for secondary indexes ○ Database statistics must be up-to-date to have a reliable sizing result What Is Changing Compared to SAP Business Suite on AnyDB? SAP HANA DB differs in few sizing principles compared to normal RDBMS. ● DB (HANA) Main Memory Requirements ● DB (HANA) CPU Requirements ● Disk Space Requirements The application server memory and the application server CPU remain unchanged.

All rights reserved. 35 1.3.4.3.1 Scaling SAP HANA SAP Business Suite powered by SAP HANA can be scaled either vertically or horizontally. There are two approaches for scaling an SAP Business Suite powered by SAP HANA system: ● Scaling vertically (scale up) ● Scaling horizontally (scale out) Scale Up This approach means that you increase the size of one physical machine by increasing the amount of the random access memory (RAM) available for processing. Restrictions to this approach are due in part to the architectural limitations of the current CPU generation. They are also due to hardware sizing being defined through the RAM to processor core ratio, in currently released use cases, and current hardware platforms only allowing a maximum number of CPUs or cores. Scale Out This approach means that you combine multiple independent computers into one system. Distributing a system across multiple hosts allows you to overcome the hardware limitations of a single physical server. This means that an SAP HANA system can distribute the load between multiple servers. This scenario is especially relevant if you have special scalability requirements and very large database sizes. In a distributed system, each index server is assigned to its own host to allow maximum performance. You can assign different tables to different hosts (partitioning the database) and you can also split a single table between hosts, known as partitioning of tables. 36 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction The concepts of vertically and horizontally scaling, and the difference between the two scaling approaches are illustrated in the following figure: The main goals of a scale-out concept for SAP Business Suite on SAP HANA are to allow for SAP Business Suite powered by SAP HANA installations with more memory with stable response times and overcome 4 TB (12 TB next year based on Intel’s new Ivy-bridge architecture) single-node scale-up restriction. Prerequisites for scale-out installations in the context of SAP Business Suite powered by SAP HANA are as follows: ● SAP Business Suite powered by SAP HANA Innovations 2013 (ERP EHP 7 SP01, SCM EHP 3 SP01, CRM EHP 3 SP01, SRM EHP3 SP01) ● SAP HANA SPS06 (required to include the relevant landscape reorganization enhancements) ● SAP NetWeaver 7.4 SPS03 (required to include the relevant migration tools) ● Approval for the scale-out on SAP HANA option for SAP Business Suite Innovations 2013 (via pilot note: SAP Note 1781986 ) For more information, see the information section.

SAP HANA multinode / scale-out deployment configurations are not supported. ● Multiple SAP HANA virtual machines on a single physical server are generally not supported. ● The maximum size of a virtual SAP HANA instance is limited by the maximum size of a virtual machine on VMware vSphere 5.5 release, which is 64 vCPUs and 1 TB of memory. ● Each SAP HANA instance / virtual machine is sized according to the existing SAP HANA sizing guidelines and VMware recommendations. Caution CPU and Memory overcommitting must not be used. ● Only single-node, scale-up configurations based on 2 or 4-socket SAP HANA certified Intel E7 Westmere EX processor or Intel E7 v2 Ivy Bridge EX processor are supported. ● 8-socket SAP HANA certified hardware configurations are not supported. ● Both SAP HANA appliance and SAP HANA Tailored Datacenter Integration (TDI) delivery methods are supported for SAP HANA on VMware vSphere. ● VMware vMotion, VMware Distributed Resource Scheduled (DRS), as well as VMware HA capabilities can be used to achieve operational performance and availability between two or more SAP HANA single-node VMs. ● Configuration and overall setup complies with current version of the SAP HANA Guidelines for being virtualized with VMware vSphere and VMware Best Practices for SAP HANA virtualized with VMware vSphere. For SAP HANA on VMware in non-production scenarios, the following exceptions to the conditions above apply: ● Besides 2-socket and 4-socket, also 8-socket single-node SAP HANA appliances or SAP HANA TDI, verified hardware configurations may be used. The Time Stamp Counter (TSC) must be synchronized between all sockets or cores. ● Multiple virtual machines may be deployed on a single SAP HANA server. Each SAP HANA database instance is to be sized the same as SAP HANA deployed on bare metal. ● Only single node configurations, no HANA DB clusters ● No overcommit of CPU and memory ● Same core-to-memory ratio applies as for bare-metal (e.g. 40 vCPUs with 512 GB memory, hyper threading enabled) 38 © 2015 SAP SE or an SAP affiliate company.

This is achieved by eliminating single points of failure and providing the ability to rapidly resume operations after a system outage with minimal business loss. Fault recovery is the process of recovering and resuming operations after an outage due to a fault. Disaster recovery deals with recovering operations after an outage due to a prolonged data center or site failure. SAP HANA provides a range of solutions to recover from faults and disasters. How to Ensure Business Continuity High Availability consists, broadly speaking, of four stages: 1. Planning 2. Prevention and preparation 3. Failure detection and recovery 4. Fix failure and failback During the planning phase, the business needs are evaluated against the cost and complexity of the different solutions. Prevention and preparation includes the selection, installation, and configuration of redundant components, standby systems, and replication. Failure detection involves integration within the existing network, system monitoring, and the management systems to provide alerts and other indicators. Based on the selected high-availability solution, recovery from failures may be automatic or manual. Failback is the process of restoring the redundancy and of replicating after recovery to be prepared for a future failure event.

The figure below illustrates the four basic HA solutions and is followed by an explanation: 48 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction A Recovery Time Objective (RTO) varies from industry to industry and depends on business requirements. Most SAP customers require an Recovery Point Objective (RPO) of 0, since data loss in a connected system environment means also restoring other, surrounding systems (for example SAP ERP connected with CRM). In summary, four basic solutions support a high availability SAP HANA implementation. ● Backup & Recovery: Regular shipping of data backups to a remote location over a network or by couriers can be a simple and relatively inexpensive way to prepare for a disaster. Depending on the frequency and shipping method this approach may have an RPO of hours to days. ● Host Auto-Failover: One or more standby hosts are added to an SAP HANA system, usually within the same data center, and are configured to work in standby mode. The standby host has no access to data and does not accept requests and queries. ● Storage Replication: The storage itself replicates all data to another location within one or between several data centers. The technology is hardware vendor-specific and multiple concepts are available on the market. ● System Replication: SAP HANA replicates all data to another location within one or between several data centers. The technology is independent from hardware vendor concepts and reusable with a changing infrastructure. Recovery - Key Performance Indicators Two commonly used key measures to specify the recovery parameters of a system following an outage are the Recovery Point Objective (RPO) and the Recovery Time Objective (RTO). Business critical systems are expected to operate with an RPO of zero data loss if a disaster takes place. To achieve zero RPO and low RTO, meaning quick availability of a secondary system, data must be replicated synchronously over longer distances to a secondary location. This synchronization might impact regular system performance and could require more expensive standby and failover solutions. Impacts are driven by network latency and additional commits from the database. This is the case regardless of the database software used. Systems must often meet higher objectives for common errors than for very rare ones, such as disasters. Recovery is the process of rapidly resuming end-to-end business after an outage. All of this results in trade-off decisions focusing on the attributes of fault recovery functionality, cost, and solution complexity. SAP offers complementary design options for DR support between data centers: storage replication and system replication. 1.3.4.5.2 Disaster Recovery The SAP HANA database supports high availability solutions for disaster recovery using synchronous disk mirroring of data and log volumes. SAP HANA Disaster Recovery - Storage Replication Cluster for Failover components can observe the productive SAP HANA database and switch to a secondary landscape using the Storage Connector API. The secondary database landscape starts at the time of the failover. SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company. All rights reserved. 49 The downtime in the case of a failover includes the start time of the database plus the time the system needs to load the essential column store tables. This solution works with by integrating the Storage Connector API of SAP in the HA solution of the hardware appliance partners. This concept is illustrated in the figure below: The replication is done synchronously or asynchronously depending on the hardware layout and the requirements of the customer. Synchronously means that an SAP HANA transaction at I/O-level is only completed when the locally persisted transaction log has been replicated remotely; that is, there is a higher latency than without replication. This method ensures that the changed and committed blocks are available at the secondary site. Replicating asynchronously means that the method does not ensure that the blocks are changed at the secondary site, but on the other hand, it has a better performance. The performance impact is to be expected for operations that change data as soon as the synchronous mirroring is activated. The impact strongly depends on a number of external factors, such as distance and the connection between the data centers. The synchronous writing of the log with the concluding COMMITs is the crucial part here. If an emergency occurs, the primary data center is no longer available, and a process for the takeover must be initiated. So far, a lot of customers be preferred to use a manual process here, but an automated process can also be implemented. This takeover process then officially ends the mirroring, mounts the disks to the alreadyinstalled SAP HANA software and instances, and starts up the secondary database side of the cluster. If the host names and instance names on both sides of the cluster are identical, no further steps with parameter hdbrename are necessary. The solution requires further design decisions, for example in the case of failover, if an SAP HANA server on the secondary side becomes the active database server, detailed implementation is hardware vendor specific. Due to its continuous nature, storage replication offers a more attractive Recovery Period Objective (RPO) than backups, but requires a reliable, high bandwidth, and low latency connection between the primary and the secondary sites. The secondary system can be used during normal operation for other purposes, such as testing and development as long as it does not influence the productive primary site in any way, for example by a shared infrastructure. If the takeover takes place, those systems must be shut down and the storage will be reconfigured for the system taken over. 50 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction SAP HANA Disaster Recovery - System Replication Using SAP HANA system replication, all data n the SAP HANA software layer, the database kernel, is transferred to another site. All secondary system services constantly communicate with their primary counterparts, replicate and persist data and logs, and load data to memory. In this mode, the secondary system does not accept requests or queries. When the secondary system is brought up in live replication mode, each service component establishes a connection with its counterpart, and requests a snapshot of the data in the primary system. From then on, all logged changes in the primary system are replicated. Whenever a transaction is persisted in the primary system, it is also sent to the secondary system and persisted there. A transaction in the primary system is not committed until the logs are replicated. This concept is illustrated in the figure below: During system replication, all data on the software layer is transferred . This concept is already known from the current SAP database installation. Depending on customer requirements for performance and data safety (RPO), SAP HANA provides different modes for replication offering control regarding RPO and performance: ● Synchronous: A database transaction is finished only when it is persisted at both sites. ● Synchronous in-memory: A database transaction is finished as soon as it is persisted on the primary site and the secondary has acknowledged receiving data into memory. ● Asynchronous: A database transaction is finished when it is persisted on the primary site and the network interface of the primary site has confirmed sending the data successfully. A complete secondary system that is configured identically to the primary stays on standby until the takeover takes place. All of the SAP HANA data is preloaded and during a takeover of the secondary node, depending on the configured mode, only a small amount of data has to be loaded into the memory. 1.3.4.5.3 High Availability Scenarios Depending on your data center operations, hardware configuration, and software landscape, you can select between several options for High Availability scenarios for SAP Business Suite powered by SAP HANA. Business Continuity, which includes Disaster Recovery (DR) and High Availability (HA), has the highest priority for the strategy of SAP in the context of AP Business Suite powered by SAP HANA. SAP works closely with hardware SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company. All rights reserved. 51 (HW) partners to provide customers a flexible choice etween different, but best-suited HW/software solutions for DR and HA scenarios. Current capabilities include, for example, single-node failover with multiple standby servers within one cluster configuration, and storage-based mirroring of SAP HANA system replication across data centers. The following examples are possible HA scenarios for SAP Business Suite powered by SAP HANA: ● Host auto-failover with a standby node ● SAP HANA system replication Host Auto-Failover Host auto-failover is a local N+m fault recovery solution (m is often 1). One or more standby hosts are added to an SAP HANA system and configured to work in standby mode. As long as they are in standby mode, the databases on these hosts do not contain any data and do not accept requests or queries. When an active (worker) host fails, a standby host automatically takes its place. Since the standby host can take over operations from any of the primary hosts, it needs access to all of the database volumes. This can be accomplished by a shared networked storage server using a distributed file system, or with vendor-specific solutions that use an SAP HANA program interface, the Storage Connector API, to dynamically detach and attach networked storage when failovers occur, for example by using block storage through Fibe Channel. This scenario is illustrated in the graphic below: 52 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction Once repaired, the failed host can be rejoined to the system as the new standby host to re-establish the failure recovery capability: SAP HANA System Replication SAP HANA System Replication is the shadow database solution of SAP with SAP HANA. The technology is similar to other shadow technologies on the database market. SAP HANA System Replication provides an extremely short Recovery Time Objective (RTO) and is compatible with all SAP HANA hardware partner solutions. System replication employs an N+N approach, with a secondary standby SAP HANA system that is identically configured as the active, primary system. Each service and instance of the primary SAP HANA system communicates pairwise with a counterpart in the secondary system. The instances in the secondary system operate in live replication mode. In this mode, all secondary system services constantly communicate with their primary counterparts, replicate and persist data and logs, and load data to memory. The main difference is that the secondary system does not accept requests or queries. SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company. All rights reserved. 53 The scenario described above is illustrated in the graphic below: Advantages with System Replication ● Memory is continuously loaded at a secondary site in preparation for the potential takeover and occupies resources ● Switchover is faster than with storage replication or mirroring (2-5 minutes) ● During the takeover of the secondary site, it is only necessary to roll forward from the latest synchronization point ● Very short performance ramp (only minutes not hours without preparation) 1.3.4.6 SAP Data Volume Management SAP Data Volume Management (SAP DVM) is a framework that helps to set up and monitor a Data Volume Management strategy that defines how to manage and reduce future data growth, and reduces the existing DB size by following a holistic approach that considers and integrates the following options: data avoidance, data summarization, data deletion, and data archiving. 54 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction Executive Summary and Key Takeaways ● Data Volume Management helps to reduce your productive data volume. ● Start reducing your data before the migration to reduce migration time, effort, and HW cost. ● DVM is a strategy that includes archiving, for which it may use your existing archiving solution, data deletion, and summarization. ● SAP provides the DVM work center in SAP Solution Manager. ● Continue using DVM as an ongoing effort to keep your data volume low. The methodology provided in this framework consists of best practices, tools, and SAP services for all stages of a DVM strategy, from the initial identification of the challenges to continuous improvement of an existing DVM strategy. SAP DVM supports the deployment and operation of a DVM strategy: ● As a proactive measure during the solution implementation ● As a proactive measure during the solution go-live ○ Starting with monitoring and analysis on regular basis ○ Minimizing data volume step-by-step according to demand ● As a reactive measure during the solution operation ○ Setting up monitoring and analysis ○ Minimizing data volume by following DVM methodology object categorization DVM for SAP Business Suite powered by SAP HANA The size of tables or complete databases is a key driver of a business downtime for certain maintenance activities such as system copies, Unicode conversions, migrations to SAP HANA, or release upgrades. It is therefore crucial to actively control and manage data volumes to reduce the downtime baseline for planned maintenance events. Additionally, you reduce your investments in the storage and efforts in operations, and achieve an optimal and stable performance in business transactions with increased data quality. DVM for SAP Business Suite powered by SAP HANA is essentially DVM for SAP Business Suite. There are two things that change: With SAP HANA as the database, memory is the driving factor for licensing. This means a more aggressive housekeeping strategy should be preferred. SAP HANA differentiates between column store and row store tables. Row store tables are stored only on the master node of an SAP HANA scale-out solution, so the available space for these tables is restricted by hardware. The overall data volume of the row store tables affects the time that is needed for a database restart, and the amount of data should therefore be kept as small as possible. For more information, see the information section.

It also helps to reduce Total Cost of Ownership (TCO) by early monitoring and controlling the development of data volume. You can use the DVM strategy to manage data volume in the following cases: ● Solution transition ○ SAP HANA migration Minimization of downtime and migration time Cost optimization ○ Upgrade, conversion, and system split Minimization of downtime ● Solution operation (proactive and reactive) Key Elements of the DVM Strategy ● Legal compliance ○ Legal regulations (country specific, for example tax and product liability) ○ Retention policy, for example retention periods, and compliance management, for example storage ○ Corporate policies ● Organizational readiness to be established ○ Advisory and responsibilities, for example auditors, and data or business process owners ○ Project, project team and role of DVM champion ● Technical readiness ○ Landscape components ready for continuous data analyses and monitoring, for example tool-based ● Implementation concept ○ Guidelines, methods, principles ○ Data governance ○ Solution categorization (shortterm, midterm, longterm) ● Operation concept ○ Operations and monitoring ○ Continuous improvement 56 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction DVM Strategy Platform The DVM work center in SAP Solution Manager is used as a platform for DVM operations. The DVM work center is used for data discovery (monitoring) and data profiling (analyzing) of the data volume on a regular basis. Data discovery and data profiling include the following features: ● Alert notification and management ● Trend analysis for individual systems (allocation statistics, utilization, and time-based distribution analyses) ● Reporting of continuous improvements (KPIs) ● Best Practice documentation ● Calculation of potential savings ● Information about archiving performed in the system landscape ● Visualization of system size and application size, and archiving (DVM planning dashboard) DVM Strategy Processes (Categorization) There are four categorization aspects for business objects or data objects: Size and Volume ● Largest and fastest-growing objects ● Objects used most, objects with oldest data, and unused data (time-based analysis) Complexity ● Fast and easy implementation of applicable reduction methods by object types (transactional, master data) ○ Housekeeping objects, for example system administration data ○ Technical objects, for example basis and cross-application ○ Business quick-win objects ○ Legally relevant business objects ● Expected saving potential of reduction Legal Compliance Business objects or data objects for which data archiving is used can be categorized by legal compliance issues, for example whether or not they use retention management. This means that,you need to define and use retention management rules for the objects, such as retention periods as criteria for the destruction of data. Solution Transition Solution transition is categorized by process issues such as upgrades, Unicode conversion, and system splits or system merges to minimize system downtime.

SAP Business Suite powered by SAP HANA Cookbook Introduction 1.3.4.7 SAP HANA Live Architecture Options Executive Summary and Key Takeaways ● Side-by-side architectures allow you to leverage SAP HANA Live without disrupting your existing landscape. ● Integrated architectures bring the full power of OLTP and OLAP integration on a single database platform. ● SAP HANA Live integrates OLTP and OLAP storage to avoid redundant data, computational overhead for aggregates, and so on. ● Virtual Data Models present queries that can be used in custom developments, specific analytics applications, or with BusinessObjects BI tools. Side-By-Side Scenario In this scenario, there are two separate systems where data is replicated by using SAP Landscape Transformation Replication Server. SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company. All rights reserved. 59 The graphic below illustrates this concept and is followed by an explanation: In the side-by-side scenario, the database tables that are used by the content packages need to be replicated from the corresponding SAP Business Suite back-end system to the SAP HANA database. This is done using SAP Landscape Transformation Replication Server. If you want to execute views from the content packages, the data from the corresponding tables must be available. Recommendation SAP recommends creating all required tables as specified in the SAP Notes corresponding to the content package and to replicate the data only for tables used in executed analytical scenarios. This ensures that no unnecessary data is replicated, that no unnecessary SAP Landscape Transformation Replication Server resources are consumed, and that no unnecessary DB memory is consumed. Data for additional tables can be replicated subsequently if you want to execute additional scenarios. 60 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction Table 10: Pros Cons ● Transaction system does not require any modification beyond replication interfaces setup ● Requires additional infrastructure to host SAP HANA Live system ● No disruption to existing operations and processes ● Requires real-time or near-time replication through SLT for data to be available in SAP HANA Live Integrated Scenario SAP HANA Live shares an SAP HANA appliance with the SAP Business Suite system, whose data is used for SAP HANA Live. Recommendation This scenario is recommended for source systems that run on SAP HANA. The graphic below illustrates this concept and is followed by an explanation: SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company. All rights reserved. 61 In the integrated scenario, you do not need to create and replicate the database tables, as they are already available in the SAP HANA database. They are maintained through the data dictionary of the corresponding ABAP application server. This means that no steps for creating tables and replicating data are relevant in this scenario. Since the ABAP server creates all tables in one specific database catalog schema (normally <SAPSID>), this needs to be mapped to the authoring schema of the imported content packages. Table 11: Pros Cons ● No replication of data required, therefore no latency for operational reporting ● Requires an upgrade of the whole transactional system to SAP HANA as a primary database ● No investment required for dedicated SAP HANA appli ance for SAP HANA Live ● Reporting processes might compete with transactional operations for system resources For more information, see the information section.

SAP HANA Live therefore does not store any aggregated or pre-calculated data. In turn, it performs on-the-fly calculation of the numbers required, based on real-time transactional data. SAP HANA Live provides reusable query views. These are designed for direct consumption by an analytical application, based on HTML5 for example, or a generic analytical tool such as BusinessObjects Business Intelligence. They are always the top view in a hierarchy of views and are not designed for reuse in other views. 62 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction What this means: ● SAP HANA Live can eliminate operational data stores that cause redundancy and latency ● It allows for decision making based on real-time data reports ● It is built on the premise that all reports should access untransformed data as a source. No business rules are applied, and transformation takes place after the reports have been executed in the Virtual Data Model ● Aggregates or calculations are not stored, but calculated on the fly at query time ● If you have an integrated landscape scenario, no replication of data is required 1.3.4.7.2 Virtual Data Models A virtual data model (VDM) is a structured representation of SAP HANA database views used in SAP HANA Live for SAP Business Suite and follows consistent modeling rules. A VDM provides direct access to SAP business data by using standard SQL or OData requests. Business data is exposed through well-defined database views, operating directly on the tables of the SAP Business Suite systems and transforming them into consistent and easily understandable views. These views can be consumed directly by rich client UIs, as for example HTML5, SAP BusinessObjects, and Excel, without any additional software layers, such as an ABAP application system in between (two-tier architecture). A virtual data model consists of the following types of views: ● Query views are designed for direct consumption by an analytical application, based on HTML5 for example, or a generic analytical tool such as BusinessObjects tools. They are always the top view in a hierarchy of views and are not designed for reuse in other views. The virtual data model also includes reuse views however, to support applications based on the virtual data model. ● Reuse views are the heart of the virtual data model. They expose the business data in a well-structured, consistent, and comprehensible way, covering all relevant business data in SAP Business Suite systems. They are designed for reuse by other views and must not be consumed directly by analytical tools. ● Private views encapsulate certain SQL transformations on one or several database tables, or even other views. They are not classified as reuse views, as they might not carry clear business semantics, but are intended to be reused in other views. They are comparable to subroutines or private methods in programming languages. A private view can be based on database. tables, other private views, or on reuse views.

These reuse views can in turn be leveraged by SAP through its own query views, for example for Analytics applications, or by end-users through custom extensions. The end-users can choose any compatible front-end tool to customize or consume the data provided by the reuse views. 64 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction 1.3.4.8 SAP HANA Target Landscapes There are three types of target landscape for SAP HANA: the two-tier, the three-tier, and the four-tier landscape. The Hardware-Efficient Approach (High Availability) Two identical hardware installations exist for SAP HANA: one for the non-production systems (DEV, QA and for DR) and one exclusively for the SAP HANA production system. This approach allows for development (DEV), quality assurance (QA), production (PRD), and disaster recovery (DR) systems. DEV and QA are installed on the same hardware as DR, meaning that DEV and QAS need to be located in the secondary data center. It is possible to run a development or a QA instance, or both, of the three-tier installation on this secondary cluster hardware, simply to use it until the take-over is executed. The take-over then stops these DEV and QA instances and mounts the production disks to the hosts. An additional set of disks for the DEV and QA instance is required in this case. The concept described above is illustrated in the following figure: 1.3.4.8.1 Two-Tier Landscape If you are working to a very tight hardware budget, you need two dedicated servers: one for productive use and one for development, and possibly also QA. You can create the QA system as an additional system on the same SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company. All rights reserved. 65 HW as the development system using the SAP HANA On-Site configuration Tool. SAP supports running multiple SAP HANA databases on a single non-production (MCOS scenario). System Deployment Possibilities The minimum landscape setup consists of development (DEV) systems and production (PRD) systems. To set up PRD systems, you could have a bare metal single-server or Scale-Out systems with an option of SAP HANA as appliance or tailored data center integration. DEV and QAS systems can be set up with the MCOS scenario by using single hardware. This concept is illustrated in the graphic below: 66 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction With the SAP HANA On-Site Configuration tool customer-specific configuration, that is not available within factory installation, can be changed or adapted. The illustrated scenario is normally used for non-productive landscapes: 1.3.4.8.2 Three-Tier Landscape Having dedicated hardware for each tier ensures stability and availability. This is also a mature environment in production support mode. In SAP HANA environments, the quality assurance system (QAS) should reflect the production system (PRD) as closely as possible and be a full copy of it. This is the prerequisite for realistic volume tests. With the flexibility provided by having a separate system in each tier, all changes can be created in the development system (DEV), while all tests can be carried out n QAS before transports are imported o PRD. The three-tier landscape incurs the lowest costs, but poses quality risks in case of high project activity. Using multiple clients in DEV only partly mitigates these risks. SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company. All rights reserved. 67 Recommendation To mitigate risks, a recommended procedure is for all projects to go live at the same release date when projects for the next release date have ideally not started yet. The sandbox system can be also added temporarily and be used for prototyping new functionalities or new releases. There is no transport path between the sandbox system and DEV system. This concept is illustrated in the graphic below: System Deployment Possibilities To set up QAS and PRD, systems you could have a bare metal single-server or Scale-Out systems with an option of SAP HANA as appliance or tailored data center integration. To set up a DEV system, you can use the virtualization option with VMware with VMware vSphere. 1.3.4.8.3 Four-Tier Landscape This landscape is the best practice for solutions with production support and for development projects of medium scope, even in parallel releases. As it allows for staged testing, using multiple clients in DEV is possible, although not necessary. In SAP HANA environments, the preproduction system (PRE) should reflect the status in the production systems (PRD) as closely as possible and be a full copy of it. This is the prerequisite for realistic volume tests. All changes are created in DEV. The QAS is used as a testing environment for integration testing and data conversion testing. This system partially contains the changes from the new release that currently is in development. The PRE is the environment for the final integration test, once the scope of the release is fixed (release test), and a regression test and a technical system test have taken place. The PRE must not be corrupted with new release functionalities or new maintenance packages before the designated time, ideally as close to go-live as possible, and should be refreshed from PRD on a regular basis, if possible. This landscape makes the best possible use of change management for production support and project development. The development team can do both, product changes and support.. The sandbox system can be also added temporarily and be used for prototyping new functionalities or new releases. There is no transport path between the sandbox system and DEV. 68 © 2015 SAP SE or an SAP affiliate company. All rights reserved.

To set up a DEV and QAS system, you can use the virtualization option with VMware with VMware vSphere. Alternatively, DEV and QAS systems can be set up with the MCOS scenario in single hardware. 1.3.5 Project Planning This chapter points out particular considerations when planning your migration to SAP Business Suite powered by SAP HANA. Executive Summary and Key Takeaways ● Data volume, custom code migration, and testing plans can significantly influence cost and effort or introduce risks in a Suite on HANA deployment project. ● Tools and accelerators may aid in project planning. ● Services are available to assist your implementation from the planning phase through the run phase of your project. ● An example high-level project plan for a rapid deployment of SAP ERP on SAP HANA is included. Phases and Project Timelines Phases For more information about the project phases, see Migration Project Phases linked in the information section. Timelines Migrating your SAP Business Suite application, such as SAP ERP, to the SAP HANA database, can be quick with a rapid deployment solution. See the sample schedule below for an overview of the project activities and basic time periods. SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company. All rights reserved. 69 Note Keep in mind that the project timeline for your SAP Business Suite on SAP HANA implementation depends on your specific system and requirements. Effort, Time, and Risk Influences ● Testing Protocol: Testing is commonly the largest area of effort in an implementation project. The testing requirements, that is how well the test scripts are defined prior to testing, whether testing is automated or has to be done manually, and the general testing and approval requirements and practices of your organization, are key factors that influence the time required for testing and the number or type of testing periods. For more information, see Test Management linked in the information section. ● Data Size: The size of the overall database influences the implementation project in many ways. It impacts initial hardware costs as well as operational costs, time required for many technical and functional steps, and impacts user efficiency. For more information, see Data Lifecycle Management linked in the information section. 70 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction ● Pool and Cluster Tables: The size of these tables influences the time required for converting the tables into transparent tables. ● Level of Customization: The number of custom objects influences both the SAP ERP enhancement package update and the effort needed to recognize the full benefit of the SAP HANA database because custom objects need to be evaluated for code optimization. For more information and detailed guidance, see Custom Code Migration and Optimization linked in the information section.. ● Current System Release and Versions: The current application release may require an enhancement package upgrade, which may introduce additional steps including regression testing. There may also be upgrades needed for integrated systems or add-ons. For more information, see chapter Value Discovery, linked in the information section, and follow the official guides for installation of the system. ● Add-Ons: Ensure that any implemented add-ons are certified prior to starting the migration to SAP Business Suite powered by SAP HANA. For notes related to add-ons, see chapter Value Discovery. ● Hardware Specifications: The number of CPUs and the amount of memory are fundamental items affecting the time required for tasks and the costs of hardware. ● Network Bandwidth: Bandwidth influences the data transfer rate between systems. ● Hardware Location: The hardware location and proximity to one another influences the latency of data transfer. Example For example, if the target and source systems are co-located, the data transfer is typically faster than in cases where they are in different locations. Note Physical shipment of data may even be required in certain circumstances. ● Project Team Expertise: The SAP HANA skills and experience of key project team members impact the project schedule and efficiency of completing many tasks. Also, the general experience of the team related to the specific application that has to be upgraded or to implementation projects in general is very important.

All rights reserved. 71 1.3.5.1 Data Lifecycle Management Prior to an SAP Business Suite powered by SAP HANA implementation is a great time to execute your data lifecycle management policy. Your policy should outline where and for how long different types of records are stored. For example, some data can be deleted without archival and most can be deleted after archival for a certain period. Understandably, archival or deletion of data from your SAP Business Suite system as the data lifecycle management policy allows provides you with benefits in many ways. You can reduce capital and operating hardware costs as well as other operating costs by shrinking the size of your database since you are storing and moving less data both during the project and during routine operations after go-live. This also equates to less risk with less downtime during the project and afterwards. You also have less business risks by adhering to your data retention policy and your users can gain efficiencies with less data that have to be interpreted and managed. Recommendation Therefore, it is strongly recommended to perform housekeeping of your system and remove any unnecessary data from the SAP Business Suite application as part of preparation for your deployment of SAP Business Suite powered by SAP HANA. To identify large tables in your landscape to review them for potential reduction, you can use SAP transaction SMIGR_BIG_ROW_STORE_TABS as referenced in SAP Note 1634681 . You can access the Data Volume Management guided self service at SAP Enterprise Support Academy Guided Self Services under Data Volume Management (DVM) - Service session . For more information, see the information section. Related Information SAP Note 1872170: Suite on HANA memory sizing Best-Practice Document Data Management Guide for SAP Business Suite 1.3.5.2 Custom Code Migration and Optimization Optimizing standard SAP Business Suite code has resulted in significant performance improvements in many transactions and processes. Similarly, the custom code in your environment needs to be evaluated to determine which modifications should be made to maximize the benefit of SAP HANA and the priority of the modifications. Some custom code may need to be modified to avoid performance degration. Caution Custom code migration is an area of risk if sufficient resources with appropriate knowledge are not allocated for the project. A best practices and recommendations guide has been published to help you plan and execute the custom ABAP migration and optimization activities. The guide contains explanations of many tools that assist you during the optimization process and that include familiar transactions such as STAD, SAT, and ST05, as well as new tools 72 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction such as the SQL Monitor, the enhanced SAP Code Inspector, and the SQL Performance Tuning Worklist. The guide also provides you with recommendations for using these tools. To have a more accurate picture as a basis for determining your code optimization activities, you can activate usage analysis, that is Usage and Procedure Logging (UPL) or SQL Monitor (SQLM), or both, as early as possible in your productive SAP Business Suite environment. This is the basis to prepare for custom code assessment even before you start with the SAP Business Suite powered by SAP HANA transition project. For more information, see Considerations for Custom ABAP Code when Migrating to SAP HANA - Best Practices and Recommendations linked in the information section. When planning your code migration and optimization, see the current guidelines for code optimization so that you are aware of the related tools and educational opportunities. For more information on golden rules, tools, and other aspects of code modification to fully use SAP HANA, see Code Migration and Optimization linked in the information section.. If you need assistance in modifying your custom code, several SAP services are available. Related Information Code Migration and Optimization [page 96] Considerations for Custom ABAP Code when Migrating to SAP HANA - Best Practices and Recommendations 1.3.5.3 Downtime Minimization The migration of existing SAP Business Suite systems to SAP Business Suite powered by SAP HANA involves the update of the application's enhancement package and the subsequent migration of the database. These activities can be performed with different approaches to system outages. Strategy 1: Combined EHP Update and Migration With Software Update Manager (SUM) 1.0 SP9 or higher, you can combine the update and migration to SAP HANA for SAP Business Suite systems. Database Migration Option (DMO) minimizes the effort required for testing, system preparation, and other activities while also minimizing the production downtime. There are certain prerequisites and requirements. For more information, see SAP Note 1875197 : Conditions: Using DMO of SUM for Business Suite systems. Strategy 2: EHP Update and Migration with One Planned Downtime The update of the SAP Business Suite application and the migration to the SAP HANA database are performed as two tasks during one outage. This approach minimizes the effort required for some preparatory project steps, for example the isolation of systems, because they are performed only once. However, the outage is longer than the individual outages for update and migration. SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company. All rights reserved. 73 Strategy 3: EHP Update and Migration with Two Planned Downtimes The update of the SAP Business Suite application is performed during one outage and the migration to the SAP HANA database is performed during a subsequent outage. This approach minimizes the disruption in business operations because there are two shorter production outages. However, this approach results in additional effort for preparation or any step that is required for the update and the migration. For more information, see the information section.

All rights reserved. 81 1.4.2 Technical System Migration Executive Summary and Key Takeaways ● Database Migration Option (DMO) combines system upgrade and migration ● Migration steps are simplified and business downtime is reduced ● The source database remains consistent, so a fast fallback is possible ● Database Migration Option has less prerequisites for the existing DB software level At several stages during the lifecycle of your SAP solution, you are required to copy or migrate your system. SAP recommends copying your system to create test, demo, and training systems for example. If you need to change your operating system, database, or both of them, you have to migrate your SAP system. During a migration process, all data is ported from a source database and imported to a target database. If you are using SAP Business Suite on HANA, you are required to upgrade your existing system and migrate to HANA. There are various techniques that can be used to copy and migrate an SAP system: ● Copy an SAP system without changing the operating system or database (homogeneous system copy) ● Copy an SAP System while changing the operating system, database, or both (heterogeneous system copy) Homogeneous System Copy The main purpose of a homogeneous system copy is to build a test, demo, or training system, or to move a system to a new hardware. The difference to a heterogeneous system copy is that both the database and operating system remain the same. On some platforms, the system can therefore be copied by using databasedependent methods, such as backup or restore. Note Regardless of whether you change the version or bit version of either the operating system or the database, the system copy is still considered to be a homogeneous system copy. The Microsoft Windows 2000 32-bit system is copied to the Microsoft Windows 2003 x64 system for example. Heterogeneous System Copy (Migration) The main purpose of a heterogeneous system copy is to create a copy of an existing SAP system on the platform where either the operating system, database, or both the operating system and the database, differ from the operating system, database, or both the operating system and the database, of the source system. The whole migration process consists of five main steps (described in detail in the system copy documentation): 1. Preparatory steps in the source system 82 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction 2. Export of the data of the source system to a database-independent format 3. Transfer of the exported files to the target host 4. New system installation together with data import 5. Post-processing steps in the target system 1.4.2.1 Migration to SAP HANA For the migration to SAP HANA, several migration path options are available. ● New Installation: Install a new system on SAP HANA without changing your existing system and transform the existing solution by selective migration. ● The classical migration of ABAP systems to SAP HANA: The heterogeneous system copy by using the classical migration tools Software Provisioning Manager 1.0 and R3load. ● One step upgrade and migration with Database Migration Option (DMO) of Software Update Manager (SUM): This is provided with DMO in Software Update Manager and is planned to become the standard migration option when migrating to SAP HANA. New Installation Install a new system based on SAP NetWeaver Application Server ABAP 7.40 in parallel to your existing system and transform the existing solution by selective migration. The advantage of this approach is that there is no risk for the production system and you get a clean system without outdated data. Considerations for New-Installation Approach ● Not suited to replace the current production system ● Requires transfer (transport, migration, and load) of relevant business data ● Additional hardware can be required for the application server ● No real data and performance comparison possible SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company. All rights reserved. 83 Recommendation For systems with resident transactional, data such as SAP Business Suite, this option is recommended for testing the overall SAP HANA approach and for gaining first experience, but not for migrating or replacing your current production system. Classical Upgrade and Migration to SAP HANA You can upgrade your existing system and then perform the database migration, such as heterogeneous system copy by using standard tools, for example, Software Provisioning Manager, SAPinst, R3load, and Migration Monitor), with the classical migration procedure for databases. When you migrate a system to SAP HANA with the classical approach, the following steps are required: ● Dual-Stack Split This applies to any kind of migration whenever a dual-stack sytsem is involved. For more information, see Prerequisites linked in the information section. ● Upgrade or Update: If your system has a lower release then upgrade it to the latest product supported by SAP HANA (SAP ECC 6.0 EHP 7). If your SAP Business Suite system already has the right release but an enhancement package not supported by SAP HANA, apply the required enhancement package (enhancement package 7). ● Heterogeneous System Copy: Database Migration Perform the heterogeneous system copy as described in the SAP HANA System Copy Guide that is available in SAP Service Marketplace at http://service.sap.com/sltoolset under Documentation System Provisioning SL Toolset 1.0 System Copy: Systems Based on SAP NetWeaver <Release> <Platform> . If you have a non-Unicode system, perform a Unicode conversion before the migration or plan a migration combined with a Unicode conversion. Recommendation Only if the standard Database Migration Option (DMO) of Software Update Manager (SUM) does not meet your requirements (for example, because DMO of SUM is not yet available for your scenario or platform and you want to perform the migration now, or because you prefer clear separation of tasks to the “big-bang” approach of DMO), consider using the classical migration with a heterogeneous system copy.

With this new feature, you can avoid landscape changes (SID, host name). The SUM tool combines all relevant steps for -place migration to SAP HANA: Unicode conversion, upgrade, and migration. Migration Scenario Migrating an existing SAP system to SAP HANA requires several steps. The advantage of place-migration instead of a new installation is that the existing system is upgraded, and you are able to retain the existing system ID, host name, and connectivity, assuming that you run your SAP system on AnyDB. Required steps are dual-stack split, Unicode is converted, the database of AnyDB is updated, your SAP software is upgraded, and the database is migrated to SAP HANA. DMO Processing Overview The DMO processing steps are based on the shadow system functionality of SUM. As part of the process, SUM creates the shadow repository on the existing database until the downtime phase while the SAP HANA database is set up in parallel, for example the client and schema. The connection should be established from the source system. In subsequent steps, the shadow repository is copied to SAP HANA, the database connection of your SAP system is migrated to the SAP HANA database, and then the downtime starts. After migrating and converting the application data, the upgrade is finished, and the new system runs on SAP HANA. The traditional database continues to run without being modified, and thus remains as a fallback throughout the complete process. DMO Phases During the Procedure The main differences to the standard upgrade procedure are following: ● Replacement of the “Switch of shadow tables” step from he standard procedure with the migration steps of the In-Place Migration Upgrade.

For more information, see the information section. Related Information SAP Help Portal: SAP HANA Platform SAP Help Portal: SAP HANA Live for SAP Business Suite 1.0 1.4.3.1 Activate To activate SAP HANA Live, an initial table has to be created in accordance with the database being used. Virtual Data Models also need to be imported, and data has to be replicated. For further information, read on. Initial Table Creation in SAP HANA Live Note Creating an initial table is necessary for side-by-side scenarios. Depending on the product you use, certain tables must be replicated. For a list of the tables you have to replicate, see the following SAP Notes: Table 13: Package SAP Note Number All packages 1782065 Suite : Tables for SAP HANA Analytics for SAP Business sap.hba.ecc 1781992 : Tables for SAP HANA Analytics for SAP ERP 1.0 sap.hba.crm 1782066 : Tables for SAP HANA Analytics for SAP CRM 1.0 sap.hba.scm 1782067 : Tables for SAP HANA Analytics for SAP SCM 1.0 sap.hba.grc 1782068 : Tables for SAP HANA Analytics for SAP GRC 1.0 sap.hba.gts 1780655 : Tables for SAP HANA Analytics for SAP GTS 1.0 Note Creating an initial table is only necessary in a side-by-side scenario. This means that your production system uses another database as its primary data repository, and that a replication is in place with a SAP HANA 90 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction database to feed the SAP HANA Live reporting system. If the tables are not created in the SAP HANA database of SAP HANA Live, the replication will not have any structure to actually replicate the data. This activation is not necessary in an integrated scenario. In an integrated scenario, your production system and SAP HANA Live both use the same SAP HANA database as primary data repository. SAP HANA Live directly queries the existing production of SAP HANA tables to produce its report outputs. Import Virtual Data Models To obtain the available VDM for your components, customers can either refer to the SAP Software Download Center (SWDC), or use the Maintenance Optimizer with SAP Solution Manager to download the SAP HANA Live packages. Each SAP HANA Live component has its own VDM package, as listed in SAP Note 1759574 . Initiate Data Replication Using the SAP HANA Live browser, customers can search, browse, tag, and consume SAP HANA analytical content views by using an Internet Web browser. Customers can also use this application to define a list of tables that are included in the SLT driver to set up the data replication. Once the data replication has run its course, the VDM data model can populate data in the predefined Private, Reuse and Query views. 1.4.3.2 Extend This topic provides a more detailed overview of the functionality and advantages of the SAP HANA database. It also provides you with information on SAP HANA Extended Application Services and on the SAP HANA XS server. Traditional application-development structures use interfaces to manage and query their data. This requires an additional intermediary controller component or an application server, acting as a broker between data representation or applications and the actual database model. SAP HANA greatly extends the traditional database server role. SAP HANA functions as a comprehensive platform for the development and execution of native data-intensive applications that run efficiently on SAP HANA, taking advantage of its in-memory architecture and parallel execution capabilities. By restructuring your application in this way, you gain from the increased performance due to the integration with the data source. Moreover,you can effectively eliminate the overhead of the middle-tier between the user interface (the view) and the data-intensive control logic. To support this data-integrated application paradigm, SAP HANA Extended Application Services provides a comprehensive set of embedded services that provide end-to-end support for Web-based applications. This includes a lightweight Web server, configurable OData support, server-side JS execution and, of course, full access to SQL and SQLScript. These SAP HANA Extended Application Services are provided by the SAP HANA XS server, which provides lightweight application services that are fully integrated into SAP HANA. It allows clients to access the SAP HANA SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company. All rights reserved. 91 system through HTTP. Controller applications can run completely natively on SAP HANA, without the need for an additional external application server. The concept of the SAP HANA XS server as part of the SAP HANA system is illustrated in the graphic below. By accessing the XS interface, developers can easily use the VDM Reuse views in order to build complex representations, reports, or applications directly on top of granular data. By combining the power of the Virtual Data Models with the functionality of rich content creation of modern development tools, you can manipulate transactional data jointly with analytical data. The application services can be used to expose the database data model, with its tables, views, and database procedures, to clients. This can be done in a declarative way using OData services or by writing native applicationspecific code that runs in the SAP HANA context. You can also use SAP HANA XS to build dynamic HTML5 UI applications. In addition to exposing the data model, SAP HANA XS also hosts system services that are part of the SAP HANA system. The search service is an example of this kind of system application. No data is stored in the SAP HANA XS server itself. To read tables or views, to modify data, or to execute SQLScript database procedures and calculations, it connects to the index server or servers, in case of a distributed system.

SAP Business Suite powered by SAP HANA Cookbook Introduction 1.4.3.3 Consume This chapter provides information about how to consume SAP HANA Live and to access data from SAP Business Suite powered by SAP HANA. SAP HANA Live provides various methods to access data and queries from SAP Business Suite powered by SAP HANA. OData Services, SAP HANA XS Connections, and Standard SQL These types of connections are made available to developers and end users who ant to create their own applications or reports using the information and data exposed by SAP HANA Live. The various views available in the Virtual Data Model (VDM) expose the data and ensure that any custom development leveraging its structures returns results in a consistent manner. The OData service model definition enables developers to rapidly create services for existing SAP HANA database artifacts. If application developers need more control over the processing logic, SAP HANA XS offers XSJS services using server-side JavaScript.

Excecutive Summary and Key Takeaways ● Activate Usage Analysis - Usage and Procedure Logging (UPL) and SQL Monitor (SQLM) - as early as possible in your productive SAP Business Suite environment. ● The longer the UPL runtime is, the more realistic is the usage picture you get. This is the basis to prepare for custom code assessment even before you start with the SAP Business Suite powered by HANA migration project. ● The data collected by SQLM together with SWLT provide a good overview of the custom code quality and help to establish the base for custom code adjustment ● Check for existing SAP guidelines and best-practice documents regarding the process of migrating and optimizing custom code. Align your internal development guidelines according to the SAP best-practice documents. ● Ask your SAP contact for available SAP services that can help you mastering your migration to SAP HANA or to support the custom code migration 96 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction Custom Code Migration and Optimization - What It Is and Why? To understand the impact of SAP HANA on your custom code, you always have to ask the following questions: ● How can custom code be adjusted to improve performance with SAP HANA? ● Is any custom ABAP code likely to cause performance issues with SAP HANA? ● Which programming rules should be applied to avoid functional issues? ● Which of the main businesses processes could potentially be massively sped up by SAP HANA? ● Which transaction should be both technically migrated and redesigned to use the full speed of SAP HANA? ● Pushing code to SAP HANA enables the full potential of SAP HANA to leverage the most important business processes and transactions.

All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction 1.4.4.1 Custom Code Migration The goal of custom code migration is to ensure that customers business processes are not impacted when migrating a productive SAP Business Suite powered by SAP HANA. Some ABAP code might be changed to avoid potential functional issues or loss of performance. When migrating a productive SAP Business Suite system to SAP HANA, it might be necessary to change existing custom or partner ABAP code to ensure the functional correctness of customer business processes (SAP HANA Code Compliance). This is only the case if custom ABAP developments rely on the technical specifications of the old database or directly access pool or cluster tables. In general, existing ABAP code runs on SAP HANA as before. Table 15: Reason Coding to be corrected DB Migration Native SQL, Hints, using DB specific features SAP HANA Architecture Depooling and Declustering ● Direct access of technical index information or of clusters or pools ● Reliance on the default sorting of DB content, which is not guaranteed For details about the SAP HANA Code Compliance requirements, see 1785057 . Custom code migration also deals with the question if any custom ABAP code were likely to cause performance issues with SAP HANA. Several scenarios immediately benefit from SAP HANA without the need for any adjustments. These include aggregations, scan on non-indexed table fields, and high physical I/O. Other scenarios require adjustments to achieve satisfactory performance. While analyzing your coding, there are a number of golden rules to adhere to in order to ensure that your custom ABAP will not cause performance issues with SAP HANA. Existing golden rules for Open SQL remain valid as general recommendations, but there have been a number of priority shifts, in the case of index definition (lower) and avoidance of nested selects (higher) for example. Simple corrections in ABAP frequently have a major impact on performance, for example replace nested SELECTs with FAE. The purpose of SAP HANA is to increase performance. However, one of the main questions is which development rules and custom code changes can help us achieve tangible performance improvement. To answer this question, follow the golden rules described below. Note These golden rules for Open SQL remain valid as general recommendations. Table 16: Golden Rules Keep the result sets small ● This means: Rule still valid SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company. All rights reserved. 99 Minimize the amount of transferred data ● This means: Rule still valid Minimize the number of data transfers ● This means: ○ Rule still valid and even more relevant for SAP HANA ○ Prefer array operations for INSERT, UPDATE, and DELETE when changing many records ○ Avoid nested SELECT loops Minimize the search overhead ● This means: ○ Rule still valid ○ In most cases, SAP HANA does not require secon dary indexes Keep load away from the database ● 1.4.4.2 This means: ○ Keep unnecessary load away from the database ○ Push down code for data-intensive calculations to benefit from SAP HANA Custom Code Optimization SAP HANA code optimization allows you to target the potentially huge performance improvements of your current performance pain points regarding business processes and transactions due to SAP HANA innovations. First, it has to be clarified which main business processes have the potential to massively speed up SAP HANA. With custom code optimization, customers can best exploit the capabilities of SAP Business Suite powered by SAP HANA and thus hugely accelerate their main business processes. In some cases, pushing code from the ABAP application level to SAP HANA unleashes the full potential of SAP HANA. SAP HANA offers advanced view modeling,for this, for example Attribute views, Analytic views, and Calculation views that are modeled or coded by using SQL script. These views can be accessed by standard SQL: ● With ABAP < 7.40 these views can only be accessed at a low level through the native SQL (ADBC - ABAP Database Connectivity) ● With ABAP 7.40 these views are natively supported in ABAP and can be accessed through the standard Open SQL. Automatic client handling can be supported, and DDIC types can be mapped. Another way to push down functional logic into SAP HANA is offered with stored procedures in SQLScript – an extension to SQL for expressing data intensive application logic. Stored procedures are invoked through the CALL SQL statement by passing the importing and exporting parameters, which can be scalars or table types. ● With ABAP < 7.40 stored procedures can be called using ADBC. This requires the following: ○ Manual handling of transfer tables for input and output parameters through temporary tables or result views 100 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction ○ Manual mapping of database types to DDIC types ● With ABAP 7.40 stored procedures are natively supported in ABAP ○ Exporting and importing parameters, for example for function modules (including mapping parameter to DDIC types) 1.4.4.3 Custom Code Assessment A custom code assessment is executed in the customer's current system landscape and consists of three parts: the code analysis, usage analysis, and definition of the master work list. Code Analysis With regard to SAP HANA code compliance, the enhanced Code Inspector offers static, rule-based checks to easily find the code patterns that require corrections. The result of this analysis should be a complete list of all mandatory findings. Usage Analysis The analysis of the custom code that is currently used is probably the most important part. It helps to identify and quantify the affected coding and consequentially reduces the overall adjustment effort. To get a realistic code usage profile, the usage analysis is normally run in a productive system or at least in a test system where realistic tests are running. The result is a list of codings with the highest and the lowest footprint. Custom code migration is a substantial part of any system upgrade. With SAP HANA, certain technology aspects have changed, for example cluster and pool tables, and custom code needs to be adjusted over and on top of other modifications. At the same time, many custom developments are not used any more. Custom Code Usage Analysis monitors your productive system environment and show you which custom code is critical and which is not used any more. Usage monitoring with the SAP standard tools does not have a significant impact on productive operations. It is advisable to keep it activated for a longer period to provide qualified results. SAP offers two standard tools to run the usage analysis ● Usage and Procedure Logging (UPL) ● ABAP SQL Monitor (SQLM) Usage and Procedure Logging (UPL) is a new functionality available with any ABAP-based system based on the core functionality of SAP Coverage Analyzer. UPL becomes standard with SAP Netweaver 7.01 SP10 or 7.02 SP9 + Kernel 720 Patch 94 or 7.31 SP3 and 7.40. In a live ABAP-based SAP system, a large number of different SQL requests are executed by the most diverse processes. To find performance hotspots and also potential for optimizations in this very broad SQL load profile, you require specialized SQL monitoring tools that also provide a connection to the running ABAP processes. The new ABAP SQL Monitor (SQLM) allows monitoring the performance of ABAP SQL executions in productive ABAP system, and links back to the driving entry point of the related business process, for example transaction code, report name, RFC module, and URL. Aggregated performance key figures, such as number of executions, SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company. All rights reserved. 101 execution time, and records read, are collected per ABAP SQL command. This provides total transparency of the running SQL in production environment and after a certain active SQL monitoring phase, for example, one day, one week, or one month, the collected SQL monitor data can be used to answer, for example, the following questions: ● Which SELECT in the customer code is executed most frequently in production? ● Which SELECT statements cause the longest runtime? ● Which SELECT in the customer code reads the most data? ● What does the SQL profile of the report XYZ or of transaction ABCD look like? For more information about the availability and necessary preparation steps of the SQL Monitor, see OSS note 1885926 . Standard analysis tools such as SQL trace or ABAP runtime analysis do not provide realistic picture because the data volume, scenario, and usage of the analyzed transactions might be different in day-by-day business in production. You might also miss a lot of processes, such as RFCs and batch processes, which represent the main productive business scenarios containing a significant amount of SQL performance potential. Define Master Work List Generally, the definition of the master work list is a topic that requires the involvement of various parties, for example business, development, and IT. This approach ensures that customers set the focus on custom code modifications that have to be considered for the purpose of core business processes. To define a prioritized list of custom code that has to be changed, you merge usage data of the dynamic assessments with the affected static coding analysis. ● Define context from business perspective (entry point, transaction, involved data) ● Detect places with best cost and benefit ratio ● Find places where code can be pushed down to SAP HANA ● Fix performance bugs and unexpected database accesses ● Identify and exclude unused code SQL Performance Work List Tool (SWLT) provides the functionality to combine, the static performance check results for a given SQL statement with the relevant runtime data from a productive system. This combination of data makes it easy to rank and filter the list to generate an optimized SQL performance tuning worklist. 102 © 2015 SAP SE or an SAP affiliate company. All rights reserved.

This methodology is based on Solution Manager applications. Context The innovative concept of Custom Code Management from SAP provides a comprehensive insight on how companies can efficiently and effectively manage their home-grown custom code. From conception to retirement, Custom Code Management delivers transparency on custom code objects, automates the analysis of every change, and clearly identifies the objects' usage, utilization, and business impact. It also supports the optimization cycles with a project-based approach to reduce the custom code footprint. SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company. All rights reserved. 103 This allows you to find SAP HANA optimization potential in existing ABAP custom code. Note There is no need to adapt all objects. Just focus on the most critical objects in terms of usage and impact. For more information, see the information section. Procedure 1. Capture the custom code footprint using Custom Code Lifecycle Management (CCLM). 2. Reduce the scope to objects that are used by leveraging Usage Procedure Logging (UPL). 3. Identify the impacted objects using ABAP SQL Monitoring (SQLM), Code Inspector (SCI), and ABAP Test Cockpit (ATC). 4. Focus on objects that are critical for the business and with the most optimization potential with SAP Performance Tuning Worklist (SWLT). Related Information Custom Code Lifecycle Management (CCLM) [page 104] For more details about the Custom Code Management approach and the functional integration of the toolset, see the link above. 1.4.4.4.1 Custom Code Lifecycle Management (CCLM) Based on SAP Solution Manager, SAP provides a methodology that allows you to manage your custom code in a holistic way instead of by performing administrative tasks. This helps to improve the quality of your custom code 104 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction migration and optimization process, at the same time reducing the risk to impact other objects and the business processes. It also helps to control and lower the total costs of your SAP Business Suite powered by SAP HANA migration project. Actions on Custom Code ● SAP HANA Code Compliance: Eliminate native SQL, db hints, check access to cluster and pool tables ● SAP HANA Performance: Review business critical transactions (top <x> most used transactions) with the focus on performance ● Customer Code Compliance: Ensure code quality, comply to customer development guidelines ● Cleaning up unused code: Monitor current usage in production, remove unused code and related objects ● Review modifications: Revert to standard wherever possible, for example from modification to BAdI implementation) Managing Custom Code Challenges ● Vast amount of custom objects to be analyzed and optimized ● Several parallel development tasks such as performance, optimization, functional redesign, and modification cleansing ● Short and tight time frame ● Multiple teams, for example on-site and off-shore ● Interdependencies: Potential clashes between development teams, for example logical sequence vs. reality ● Precise coordination between development teams and test team required ● Daily reporting and detailed status tracking needed How can we… ● Get a single view on all tasks? ● Plan and dispatch? ● Monitor progress and report? To achieve this goal, the Custom Code Lifecycle Management application (CCML) in the SAP Solution Manager serves as a central tool with a central object repository to manage and track the project activities related to custom code. It supplements existing tools in the SAP Solution Manager and was developed especially for the purpose of supporting your ABAP custom code developments throughout their lifecycle. The central repository of the CCLM represents a collection of custom code objects that needs to be populated by the different code analysis tools. Assigned attributes that are provided during the object analysis phase make it possible to control the custom code change process. SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company. All rights reserved. 105 1.4.4.5 Code Adjustment SAP offers a Custom Code Migration Service for SAP Business Suite powered by SAP HANA. For customers or partners who want to carry out the migration themselves, SAP provides the code guidelines described in this topic. Evaluating ABAP Coding for Optimization on SAP Business Suite powered by SAP HANA If you have completed the migration to SAP ERP on SAP HANA within your SAP system landscapes, you can start looking at areas where the ABAP program code can be optimized for performance improvement. This applies especially to customized code in customer namespaces that you were already executing in the SAP production system. Standard application code delivered by SAP is already automatically optimized during the migration. In this case, the guide How to Evaluate ABAP Coding for Optimization On SAP Suite on HANA n be very useful. The guide primarily focuses on three standard enhanced or new mechanisms that are made available by SAP. These mechanisms help you to identify and evaluate the customized program code based on both the static and dynamic usage of the SAP ERP on SAP HANA application. The three mechanisms that will be discussed are: ● SAP Code Inspector (Enhanced) ● SQL Monitor (New) ● SQL Performance Tuning List (New) 106 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction For more information, see How to Evaluate ABAP Coding for Optimization on SAP Suite on HANA . Considerations for Custom ABAP Code During Migration to SAP HANA SAP HANA is a fully-fledged relational database system optimized for transactional (OLTP) and analytical (OLAP) processing. As the underlying database system for the SAP Business Warehouse and the SAP Business Suite, it is fully compatible based on the SQL support in the SAP NetWeaver Application Server ABAP. Due to the nature of the in-memory columnar storage in SAP HANA, there are a few recommendations to consider during the transition of custom ABAP developments to SAP HANA. The main focus during the execution of code adjustments should always be on two aspects: ● Avoiding functional regressions during migration: During every database migration, you need to revisit existing database-dependent coding based on the previous database system. This also includes coding relying on undocumented implicit behavior. ● Detecting performance optimization potential: SAP HANA allows insignificant optimization of the performance of existing ABAP developments. To fully benefit from the power of SAP HANA, certain data access patterns should be revisited and optimized, in particular when classic performance recommendations for Open SQL were not previously taken in to account For more information, see Considerations for custom ABAP code during migration to SAP HANA. This document guides customers and partners regarding existing custom ABAP developments when migrating to SAP HANA. Additionally, it contains an overview of the available tools and provides guidance on how to use them in the context of a migration to SAP HANA. In particular, it explains the steps that can be followed before a technical migration takes place. It also includes steps that need to be considered independently from SAP HANA. The document primarily addresses ABAP coding in combination with standard database access through Open SQL. For some specific environments and frameworks, additional guides and recommendations may exist. On the other hand, the document does not discuss the concrete optimizations of standard SAP code in the SAP Business Suite powered by SAP HANA. It also does not give recommendations for using native SAP HANA development options, for example column views or database procedures, to optimize the performance. Furthermore, the document is not a replacement for existing approaches for performance optimization of SAP solutions, such as system tuning and hotspot analysis. For these aspects, consider, for example, existing SAP services or similar offerings. For more information, see Best Practice Guide - Considerations for Custom ABAP Code During a Migration to SAP HANA . 1.4.4.6 Effort Estimation During the Code Analysis process, you identified the affected custom coding. After defining the functional and performance findings, you identify the critical custom code and the amount of unused code in the Usage Analysis. At this point, one of the main tasks is to obtain list of coding with the highest and lowest footprint. After merging the sage data with affected coding analysis, you can start to create the master work list that contains a prioritized list of affected custom code. Throughout the whole process, it is always advisable for various parties of business, IT or development, or all of these, to be involved. The first priority should be on bug corrections, such as missing explicit sorting. Secondly, simple corrections on ABAP with a major impact, for example a missing WHERE condition in widely used coding. The second priority should be on simple corrections in ABAP with a minor impact. Corrections of low value that SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company. All rights reserved. 107 require much effort should be reviewed closely if there is a real need for them. If you identify processes where a complete redesign is necessary to use the full speed of SAP HANA, a code pushdown to the database is necessary, for example. Recommendation We recommend setting new projects after ABAP code has been migrated. Note SAP offers the Custom Code Migration Service for SAP Business Suite powered by SAP HANA and is delivered with its own assets and service content. It contains a draft for a master work list provided by SAP. For customers or partners who want to migrate their code themselves, SAP provides different code guidelines that are described in this cookbook. To get started, you can use the Microsoft Excel template linked below to insert all functional and performance issues that you have identified during your analysis. This template provides you with an overview of the findings and a better basis for your project planning estimations. As this is not a general SAP template, it is not possible to warranty that it is complete. Consider the following points also during your planning activities and your effort estimations: ● The analysis and preparation of the customer code can start before the SAP HANA migration. The required tools do not depend on the database used and some are also available in earlier SAP NetWeaver releases. ● The functional adjustments and the first round of (simple) performance optimizations are usually very manageable and are local corrections that do not require in-depth application knowledge. ● The results of the static performance checks can generate a very high number of messages. However, this is not a cause for concern because these performance checks are of an informative nature (for example, there is a nested SELECT) and can only be effectively used in combination with relevant performance data. The addition of performance data (SQL Monitor) usually reduces the number of recommended performance correction to a low two-figure digit. ● Customers can access extensive support offered by SAP Consulting and SAP Support for the SAP HANA migration. For more information, see the information section. Related Information Code Migration Effort Estimation Template for SAP Business Suite powered by SAP HANA migration projects 1.4.4.7 Functional Test Plan During the scope identification, you can set up a functional test plan for critical business processes. In addition to ur important business processes, you need to test business transactions that include modifications and custom code. This aspect is of equally high importance, as igrating from a traditional database to SAP HANA might impact transactions that include modifications or custom code, or both. 108 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction Recommendation It is recommended to set up a functional test plan for modifications and custom code. You can make use of the static code analysis with ABAP Test Cockpit and UPL or the static and dynamic code analysis with SQL Performance Tuning Worklist (SWLT). Recommendation It is strongly recommended to create a regression test plan section especially for business process tests with adjusted custom code and modifications. The goal is to have no negative impact on critical business processes and at the same time to reduce the regression test effort as much as possible. The most efficient way to create a risk-based and effort-optimized test plan is to use the Business Process Change Analyzer (BPCA) of SAP Solution Manager. For more information, see the information section. Related Information Best Practice: Test Management for SAP Business Suite on SAP HANA Migration Projects 1.4.4.8 Tools Overview The following section provides you with a summary of tools mentioned in previous sections. These support you in your custom code migration and optimization tasks. SAP Code Inspector (SCI) / ABAP Test Cockpit (ATC) SCI is the standard tool for analyzing ABAP developments to detect potentially critical source code in terms of performance, security, globalization, or quality in general. The code is analyzed by performing a set of selected checks that can be grouped into different check variants. SCI is integrated into the ABAP Test Cockpit, a universal tool for quality assurance of custom developments. For further details about C and SCI, and w to use them, see ABAP Test Cockpit / SAP Code Inspector of the following document: Best Practice Guide - Considerations for Custom ABAP Code During a Migration to SAP HANA For more information, see ABAP Test Cockpit – an Introduction to SAP’s new ABAP Quality Assurance Tool SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company. All rights reserved. . 109 SQL Monitor (SQLM) SQLM allows you to ace the performance of all ABAP SQL executions in production, and links back to the driving business processes. The new ABAP SQLM provides total transparency of the running SQL statements in a productive environment and is a central tool to be used in your performance optimization process. Recommendation To be thoroughly prepared for custom code migration and optimization, we recommend activating LM as early as possible in your productive SAP Business Suite environment. The longer the runtime is, the more detailed e SQL trace line will be, and the more realistic the usage and performance picture of your business processes. For more information and best practices, see Optimizing Custom ABAP Code for SAP HANA – The New ABAP SQL Monitor . Usage and Procedure Logging (UPL) UPL is a new functionality available in any ABAP-based system, based on the core functionality of SAP Coverage Analyzer. It is used to retrieve usage data about all called and executed ABAP units, such as programs, function modules down to classes, methods, and subroutines. It then ends these SAP Business Warehouse. UPL does not affect your system's performance in any way, d catches usage information of ABAP routines directly when they happen. It provides you with 100% coverage of usage without estimations or evaluation of ABAP call stacks. This also includes detection of dynamically called ABAP elements. UPL is the only technology to close the existing gaps in the SAP workload statistic: ● UPL data is cross-client data and measurements are taken system-wide ● UPL data also includes indirect calls UPL will support you to evaluation the real usage after the custom code was requested and will help you to focus on the right requirements in the upcoming development cycles of custom code migration and optimization. For more information about UPL and about how to use it, see Creating Check Steps for Objects Recorded by Usage Procedure Logging and Custom Code Management Roadmap . SQL Performance Worklist Tool (SWLT) SWLT enables you to identify ABAP SQL code that has potential for performance improvement. This tool allows you to combine the result list of the new static ABAP code scans (ATC/SCI) with the runtime monitoring data of SQLM or UPL, and creates a unified worklist. This worklist allows you to rank and filter the findings according to your business process specific performance issues. For prerequisites and best practices on SWLT, see SQL Performance Tuning Worklist of Best Practice Guide - Considerations for Custom ABAP Code During a Migration to SAP HANA . For more information, see SQL Performance Tuning Worklist SWLT help . 110 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction Repository Data Analyzer (RDA) RDA is a stand-alone tool for performing static code scans to create a hierarchical ABAP code dependency tree. This dependency information can be used to identify unused code objects when cleaning up your custom code. The code scan is usually executed periodically in your QA system and allows a top-down and a bottom-up approach. RDA is offered as a project-based solution of the SAP System Landscape Optimization.

A number of golden rules should also be taken into account. You might need this information to save time, focus on the most important activities, and to benefit from the experience of others. Best Practices for ABAP Custom Code Transition to SAP HANA This guide provides you with best practices and recommendations, and gives you detailed considerations regarding custom ABAP code when migrating to SAP HANA. It describes typical usage scenarios and explains how to make use of the relevant tools. Based on the simple process model with the three phases Planning, Migrate, and Optimize it explains the recommended steps and approaches that you can use as a checklist when planning the migration project. Best Practice Guide - Considerations for Custom ABAP Code During a Migration to SAP HANA ABAP on SAP HANA - From Analysis to Optimization A considerable number of guidance documents and blogs in the SAP Community Network also provide you with best practices and guidelines. One of them is the ABAP on HANA - from analysis to optimization blog. The blog describes relevant steps to maximize the effect of ABAP performance tuning on custom coding for an SAP system running on HANA DB. It focuses on tools and guidelines delivered by SAP and starts with a procedure describing how to find candidates, for example reports and transactions, that show a significant potential to improve the performance, which optimizes the ABAP coding. In each section, different optimization aspects are discussed, starting with identifying potential candidates and ending with tips and tricks from real-live projects.

ABAP for SAP HANA SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company. All rights reserved. 115 Performance Guidelines ABAP Development on SAP HANA When planning a migration to SAP HANA, certain considerations related to existing custom ABAP code are required. This includes mandatory items that are related to a change of the database platform in general, and some additional recommendations specific to SAP HANA. If you are an experienced ABAP developer, you might know the classical performance guidelines for using Open SQL. One of the frequently asked questions is about what changes occur in the context of SAP HANA regarding these guidelines. Although, the priorities of some rules are changing, which means that some aspects are less important due to the nature of the in-memory column store, there are also certain patterns of suboptimal coding with higher impact on SAP HANA. Furthermore, there are completely new opportunities for performance tuning on SAP HANA that were not possible in the past, for example pushing complex operations to the database. Performance Guidelines for ABAP Development on the SAP HANA Database 1.4.5 Test Management Get information about how to put into practice the test management for SAP Business Suite powered by SAP HANA migration projects. Note that there is a service available offered by SAP called Test Management for SAP solutions that is also applicable for SAP HANA. Executive Summary and Key Takeaways ● Bear in mind Business Process Impact Analysis and custom code developments during your preparation phase of Test Management ● Business process experts should be involved during all of your test activities ● Use SAP Solution Manager for example for Business Blueprint, Business Process Change Analysis, and Test Reporting ● SAP provides the service Test Management for SAP Solutions for Enterprise Support Customers to set up testing for SAP applications and non-SAP applications as well as for SAP HANA and SAP Mobile Why Is Test Management in SAP Business Suite powered by SAP HANA Migration Projects So Important? Test Management during SAP Business Suite powered by SAP HANA migration projects is one of the most important tasks that you have to consider. You should therefore be aware of the most important test management activities for functional and performance tests, which allow you to migrate to SAP HANA without negatively impacting business processes executed by SAP Business Suite solutions. This is also particularly important for your custom developed applications. 116 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction What Is the Best Test Management Approach? If a company plans to migrate its actual SAP Business Suite solution from a traditional database to SAP HANA, several test and validation activities are necessary. Many companies have their own strategy and approach to handle the test management during a database migration. Recommendation It is advisable however to separate all test activities into three phases. These three phases are the Preparation Phase, the SAP Suite on SAP HANA Migration Project, and the After GoLive. For more information about these phases, see Test Management Phases. For more information about strategy, products, and capabilities provided by SAP for functional test management and change impact analysis, see the information section.

All rights reserved. 117 E-Learning Material SAP Online Knowledge Products: SAP Solution Manager 1.4.5.1 Test Management Phases The test management process consists of three phases: the preparation phase, the test execution phase, and test activities that follow after going live. Phase 1: Test Management Preparation In this phase, a status assessment followed by an approach and tool decision is recommended for the following test management aspects: ● Business Blueprint ● Test Scope Identification ● Test Planning ● Functional Regression Tests ● Performance and Load Tests ● Service Tests ● Reporting and Sign-off Recommendation SAP recommends organizing the preparation phase in separate work streams for each of these aspects. Once the status assessment and the tools decisions have been made, the test management should be set up, and planning activities should be carried out. At the end of the preparation phase, you can initiate the technical steps of the SAP Business Suite powered by SAP HANA migration project. Phase 2: Test Execution During SAP Business Suite powered by SAP HANA Migration Project During the migration project phase, the test team executes functional tests, performance and load tests, as well as service and interface tests. Business process analysts will be involved during integration tests. Any incidents that occur are analyzed, while problems are resolved, and retested. At the end of this phase, the test team signs off the test activities. 118 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction Phase 3: After Go-Live Test Activities SAP HANA Revisions SAP HANA maintenance activities are provided through SAP HANA revisions. Regression tests are required at the technical and the business process level to validate the maintenance activities. Smart test-scope identification techniques are required to avoid full regression tests that are not feasible due to time and effort constraints. SP for SAP EHP, Version for SAP HANA SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company. All rights reserved. 119 Based on customer feedback, SAP has analyzed and prioritized existing transactions. Many optimizations delivered with enhancement packages (EHPs) are active without the need for any manual steps. For a detailed list of all improvements, see the attachment in SAP Note 1761546 . Some of these optimizations have be activated in the IMG or through a Business Function, or both. For more information, see the latest release notes. Functional regression tests are therefore required at the technical and the business process level to validate the maintenance activities. Smart test-scope identification techniques are required to avoid full regression tests that are not feasible due to time and effort constraints. For more information, see the information section. Related Information Release Notes SAP ERP 6.0 EHP6, version for SAP HANA 1.4.5.2 Best Practices It is strongly recommended not to limit the test activities to technical objects. Business process tests should also be added to the overall test scope. Business process experts (BPx) should also be involved in functional integration tests. Manual test cases therefore need to be expressed in business language and assigned to the business process hierarchy. 120 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction Automated test scripts used for efficient regression tests are assigned to the appropriate business process of the business process hierarchy, which enables risk-based test scope identification. At this point, documentation of the system landscape and the business processes can be carried out with the SAP Solution Manager. Recommendation SAP recommends defining the Business Blueprint in the SAP Solution Manager, which allows you to efficiently identify the test scope and subsequently execute the test. If a Business Blueprint is missing either in part or entirely, you also have a number of alternatives available for setting up a Business Blueprint in SAP Solution Manager. For more information about SAP HANA test management, see the SAP Best Practice document Best Practice: Test Management for SAP Business Suite on SAP HANA Migration Projects. This document focuses primarily on the two most relevant SAP test options and provides you with best practices in SAP Test Management for the SAP Business Suite powered by SAP HANA migration. In this context, you will learn about best practices from SAP regarding the most important SAP test aspects such as: ● Test scope identification and test plan generation ● How to consider custom code migration in test plans ● Functional regression tests including test preparation and planning, test execution, reporting, and sign-off ● Performance and load tests including preparation and planning, and execution ● Service Tests For more information, see the information section. Related Information Best Practice: Test Management for SAP Business Suite on SAP HANA Migration Projects 1.4.5.3 Services SAP Field Services Consulting offers the Test management for SAP Solutions service. This service directly supports functional tests of strategic landscape components such as SAP HANA. The test approach of SAP is universally applicable to all applications and technologies, both for SAP and non-SAP applications. As far as SAP HANA is concerned, the key interest is performance and efficiency. It is also necessary however to ensure that HANA operates effectively and stably, producing the intended and expected result. The approach to reach this challenge is to execute end-to-end functional tests that ensure the functional correctness of the SAP HANA server, user clients, and application servers. Typical challenges in terms of quality assurance (QA) and testing include: ● The lack of a centralized testing approach ● The lack of a process-oriented approach to testing ● The lack of traceability throughout the application lifecycle from requirements to tests to defects ● Testing in heterogeneous landscapes SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company. All rights reserved. 121 ● Software updates affecting mission-critical business processes ● Risk reduction ● Third-party supplier management ● On-time and on-budget delivery ● The lack of agility ● Stacked testing due to timeline crunch Value Proposition ● Lower risk due to state-of-the-art testing tools and methodology ● Higher test quality thanks to a central testing platform ● Comprehensive and integrated reporting on all test phases ● Integration - HP QC is fully integrated with the ALM solution of SAP Service Methodology The service consists of four approaches: Test Preparation and Scope During this step, the test scope is identified, and the test is prepared. Identification Test Planning During this step, the test is planned, test cases are created, and the test infrastructure is installed. Test Execution During this step, the test is executed. Test results are analyzed and reported. Final Testing Activities During this step, the optimization potential is identified, the KPI is analyzed, and the final documentation is created. Each test approach takes place during a certain project phase or between, sometimes overlapping with the subsequent project phase. 122 © 2015 SAP SE or an SAP affiliate company. All rights reserved.

All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction Recommendation For SAP Business Suite powered by SAP HANA migration projects that are handled using test management capabilities provided by SAP Solution Manager: It is recommended to use SAP Component Based Test Automation (CBTA) for all test automation activities based on SAP GUI such as SAP ERP, or on SAP CRM Web UI such as SAP CRM. Recommendation For SAP Business Suite powered by SAP HANA migration projects that are handled using test management capabilities provided by SAP Quality Center by HP and integration with SAP Solution Manager: It is recommended to use SAP Test Acceleration and Optimization (SAP TAO) for all test automation activities based on SAP GUI such as SAP ERP, or on SAP CRM Web UI such as SAP CRM. Recommendation For systems not based on SAP GUI or SAP CRM Web UI, for example Portal, Business Objects, BW, or Crystal Reports: These systems are often part of SAP Business Suite powered by SAP HANA migration projects. It is recommended to complete CBTA or SAP TAO by using, for example, HP Quick Test Professional (QTP). Component Based Test Automation (CBTA) CBTA stands for Component Based Test Automation. It is shipped with SAP Solution Manager 7.1 SP07 and the license is included in the SAP Enterprise Support contract. CBTA allows the creation of automatic tests via a dedicated recorder. It supports scenarios on systems under test that are based on the SAP GUI or CRM WEB UI technology. Component Based Test Automation (CBTA) – Customer Benefits ● Test creation wizard for business analysts to create test scripts ● Composition of test scripts by reusing default components delivered by SAP and customer-specific screen components ● Composition of automated E2E process tests including parameter handover between the test components ● Fast repair of damaged CBTA test scripts because of modular approach ● Separation and central planning of test scripts, test data, and systems under test ● Test scripts, test data, systems under test are separated and centrally planned ● CBTA is fully integrated with SAP Solution Manager 7.1 through Test Automation Framework ● Usage rights are included for customers with SAP Enterprise Support contract Compared to eCATT (record and playback approach), CBTA test scripts follow a modular approach. Therefore, test components can be reused and damaged test scripts be repaired fast. Apart from that, CBTA scripts can be created easily by business analysts while eCATT requires developers' expertise to creation and maintain test cases. SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company. All rights reserved. 127 CBTA is composed out of 2 software components: An add-on to be installed on SAP Solution Manager 7.1 from SP7 on, and a front-end component to be installed on the user's desktop. Installation and configuration of both are described with SAP Note 1763697 . extended Computer Aided Test Tool (eCATT) eCATT enables automatic testing in SAP GUI for Microsoft Windows and SAP GUI for Java. For other GUIs and external applications, eCATT provides an interface for external tools. The tool can be used with the Test Workbench and is also integrated with the Object Navigator (transaction SE80). Features ● Test transactions, reports, and scenarios ● Call BAPIs and function modules ● Test remote systems ● Check authorizations in user profiles ● Test updates of database, applications, and GUI ● Test the effect of modifications on customizing settings ● Check system messages SAP Test Acceleration and Optimization (SAP TAO) SAP Test Acceleration and Optimization is completely integrated into SAP Solution Manager and supports you n automating your business process tests. It allows you to quickly generate automatic tests during regression testing of SAP solutions. You can create drafts of test cases, test components from transaction screens, and parametrize. These single transaction tests can be combined into a scenario test. Due to the modular test case approach, it is easier to manage potential modifications of your software that need to be considered in your test case. With SAP TAO, you can set up your tests based on generated modular test components and therefore significantly facilitate the maintenance of your test cases. Recommendation To build automated regression tests, it is strongly recommended to deploy SAP Test Acceleration and Optimization (SAP TAO) in conjunction with SAP Quality Center by HP. Note SAP TAO is shipped on a license-based cost model. 128 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction Table 18: SAP TAO Features Feature Description Test Creation You can easily record and execute tests. To build tests, you can use the default components of SAP TAO. The subject matter expert (SME) needs less time to explain the business process to QA experts. Regeneration of Components Affected You can regenerate any number of components whenever there is a change to the business process. Test Consolidation To speed up the test execution, you can consolidate a test into a component and use it in a scenario test. Test Execution You can execute multiple tests at the same time in SAP Qual ity Center You can also create or update technical bills of ma terial (TBOM) for associated SAP Solution Manager items. SAP Quality Center by HP The SAP Solution Manager adapter for SAP Quality Center by HP supports role-specific testing and covers the complete testing process, from collecting the requirements to defining the test case and reporting. This infrastructure is therefore easy for customers to implement and use, as it follows the typical testing process for SAP solutions. Using the adapter, customers can seamlessly transfer information about business processes and test assets, Business Blueprint structures and test objects for example, from the SAP Solution Manager to SAP Quality Center by HP. SAP Quality Center by HP is the main testing environment for the customers' quality teams. Once the test is complete, the test results are transferred from SAP Quality Center by HP directly o SAP Solution Manager, automatically displaying the results of the predefined tests. This helps project leads to gain increased control over testing processes and allows customers to reuse this information during subsequent application management phases, for example upgrades or continuous business improvement projects. This integration allows the functional experts to trace the status of the business process test in the SAP Solution Manager, while quality experts continue working in SAP Quality Center by HP. Business Process Change Analyzer (BPCA) With the Business Process Change Analyzer you can identify business processes or business process steps that are affected by planned change events. It is available in the Work Center Test Management of SAP Solution Manager. The underlying technology of BPCA is the Technical Bill of Material (TBOM). A TBOM is a list of ABAP objects assigned to a transaction as part of your business process documentation, that is a record of all the inventories related to a transaction. Particularly, a TBOM is created by recording the transaction code. BPCA analyzes the change impact and identifies the potential impact on your existing business processes. The purpose of this application is to identify core business processes that are affected by a change event such as a custom code change, or an SP or EHP upgrade. This is done by comparing the TBOM, which lists the SAP objects SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company.

One of the main goals of your migration project is to achieve satisfactory overall performance while keeping the application stable. Be aware that the more functional enhancements, new or changed business process requirements, or system landscape consolidation topics you add to the project scope, the more complex and more costly your testing becomes. Business testing needs to cover all relevant process areas. The main drivers are usually the following: Order to Cash, Accounting/R2R, P2P, and Controlling. 130 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction Integrity Checks To compare the results of any DB and SAP HANA DB, add integrity checks to your test activities for the most relevant tables (50+ tables) . ● Check if the row count results of SAP tables are identical in SAP HANA and in the classic DB ● Calculate the hash totals and run a comparison ● Check if table structures on SAP HANA DB have been converted correctly into the column store format Performance Tests ● To quantify the system performance, measure the runtime of your core business processes in the productive system before starting the SAP HANA performance tests. Note Bear in mind that the system load can vary during daily operation hours. All test cases should be executed several times and at different times of the day. ● Carefully plan when to execute which tests. Recommendation We recommend running performance tests in an exclusive mode, as the results could be influenced by mass load tests. Load Test - CRM on SAP HANA Test Description The aim of the load test was to create a massive BDoc load on the CRM middleware. To achieve this, more than 100 online users created more than 1000 BDocs per hour. The background jobs ran parallel too, while the main ones ran during peak hours, like in the productive system . Test Result The test showed that the required load of 150% of BSP and E-Shop requests was achieved for the simulated scenarios. The number of generated BDocs and RFC calls through the CRM middleware from ERP system also provided 100% of the load that was expected during peak hours in the productive CRM system. The CPU utilization showed no bottleneck situations on the CRM ABAP instance during any tests. Based on the hourly average CPU utilization of 65%, the estimation is that the system could manage even 50% more middleware load and 50% more online users.

The security needs of current and future business applications are met with a rich set of authorization mechanisms. ● You can consistently optimize your ABAP custom code, and redesign and optimize individual business process cycles ● Transports are used to deploy software components or objects across various landscapes, for example from development to quality to production. 1.5.1 Monitoring Executive Summary and Key Takeaways ● To ensure the smooth operation of your SAP HANA systems, it is important to monitor the operational status and the most important key performance indicators of the database on a regular basis. ● For monitoring purposes, both SAP and third-party tools can be used. Each of the tools has its own appeal and advantages. These range from being able to display server activities in isolation to the offer of a solution to the problem - the root cause analysis. Monitoring SAP HANA DB To ensure the smooth operation of your SAP HANA systems, it is important to monitor the operational status and the most important key performance indicators of the database on a regular basis. These include system availability, memory usage, CPU consumption, disk usage and alerts. To monitor these indicators, you can use the monitoring tools listed below, as well as various views in the SAP HANA database. ● For system availability, the complete HANA architecture including the name server, index server, statistics server, preprocessor and SAP HANA XS is monitored. ● The statistics server reports alerts for the system when resource usage of database and statistical thresholds are violated. These are displayed as Low, Medium or High priority. 132 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction ● Disk usage monitors the amount of memory on the disk and the memory available for storing data files for SAP HANA. ● Memory usage is a critical SAP HANA resource. The memory pool is used for storing in-memory tables, for thread stacks, and for temporary computations, intermediate results and other data structures. For more information, see SAP HANA Memory Usage Explained. To monitor used memory, you can use the monitoring tools listed below, as well as various views in the SAP HANA database. For more information, see the information section. Monitoring SAP HANA Systems To ensure the smooth running of your SAP HANA systems, it is important to monitor system availability and key performance indicators regularly. The SAP HANA studio includes several tools for monitoring your systems: ● System Monitor: This editor provides you with an overview of all your SAP HANA systems at a glance, including system availability and current resource usage information. From the System Monitor you can drill down into each individual system in the Administration editor. ● Monitoring Dashboard: This Web-browser based view visualizes key aspects of system health and configuration on a single screen with the option to drill down to more detailed views. ● Administration: This editor provides detailed information about resource usage, current alerts, system performance, system configuration, as well as tools for analyzing and troubleshooting issues in your system.

From the System Monitor, you can drill down into the details of an individual system in the Administration editor. To see all information for all systems, you must have either the MONITORING role or the system privilege CATALOG READ and the object privilege SELECT on the schema _SYS_STATISTICS. Monitoring Dashboard The Monitoring Dashboard visualizes key aspects of system health and configuration on a single screen with the option to drill down to more detailed views. The SAP HANA studio includes a Web browser-based dashboard that visualizes key aspects of system health and configuration, such as current high and medium priority alerts, memory and CPU usage, availability of data backups, and so on. From the dashboard, you can drill down to views containing more detailed information. 134 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction To be able to access the Monitoring Dashboard, you must have the role sap.hana.admin.roles::Monitoring. This role is not granted by default to the standard MONITORING role. Therefore, a user administrator must grant the role to your user explicitly. To grant this role, a user administrator requires the object privilege EXECUTE on the procedure GRANT_ACTIVATED_ROLE, in addition to the system privilege USER ADMIN. Administration Editor To identify problems early and avoid disruptions, you need to monitor your systems continuously. While the System Monitor provides you with an overview of all systems at a glance, the Administration editor allows you to drill down into the details of resource usage and performance for each system. In the Administration editor, you can monitor the following: ● Overall system state and resource usage by system and host ● Status and resource usage of all system components, for example, name server, index server, and so on ● Auto-failover status and configuration of hosts in distributed systems ● Alerts issued by the system in relation to its status, performance, and resource consumption SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company. All rights reserved. 135 ● Disk space consumed by system processes for the various storage types (data, log, and trace) ● System performance, for example, by analyzing performance indicators such as expensive statements, running threads, and load history To open the Administration editor with read-only access to the system views and alert information, you must have either the MONITORING role or the system privilege CATALOG READ and the object privilege SELECT on the schema _SYS_STATISTICS. 1.5.1.2 Monitoring Options You can monitor the SAP HANA database with SAP HANA Studio, DBA Cockpit, SAP Solution Manager, thirdparty tools, or SAP NW LVM. Monitoring with SAP HANA Studio One way of monitoring is using the SAP HANA Studio. As the Studio is part of the SAP HANA Appliance, no extra licenses are required. For a quick overview, you can use the System Monitor. This can be used to monitor system availability and the operational status of the SAP HANA system. Defined alerts inform the user critical situations on the database. The SAP HANA Studio also provides information about memory consumption of SAP HANA, CPU usage, disk usage, status of system replication, session monitoring, display information of individual steps of statement execution (most expensive statements for example) and much more. The statistics server is the basis for the SAP HANA Studio and provide historic monitoring data. SAP HANA Studio can be used to define thresholds for when a system status should be reported as critical. 136 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction Monitoring with DBA Cockpit To monitor the database, you can also use DBA Cockpit, which retrieves the alerts from the SAP HANA database. In DBA Cockpit, all of the main monitoring functionalities in the SAP HANA Studio are supported. The statistics server is also the basis of DBA Cockpit and provides historical monitoring data. DBA Cockpit can be used to define thresholds for when a system status is reported as critical. DBA Cockpit is part of SAP Basis. No extra licenses are required. The system administrator might need to grant authorizations for this tool. Monitoring with SAP Solution Manager SAP Solution Manager provides another option for monitoring the SAP HANA database and the layers above. Solution Manager communicates with HANA via the host agent and the diagnostic agent. Alerts are read from HANA here and passed on to Solution Manager. Solution Manager can be used to define thresholds. A threshold defines the point at which a system status is shown as critical. SAP Solution Manager also provides an automated regular status check of your SAP solutions: SAP Early Watch Alert (EWA). This tool monitors the essential administrative areas of SAP components and keeps you up to date on their performance and stability. To facilitate quicker problem solving, a root cause analysis is also provided. A part of the root cause analysis is the End-to-End Analysis. Starting with the application and ending on the database level, issues can be isolated and identified by using this analysis type. If you have a maintenance contract with SAP, SAP Solution Manager can be used without a license. Monitoring with Third-Party Tools and SAP Solution Manager SAP Solution Manager can also be used in combination with third-party monitoring tools. Solution Manager then serves as a “relay station” for monitoring information for external monitoring tools. This is an interesting alternative if the company in question already uses monitoring tools, but these tools cannot access SAP HANA. There is no interface certification for HANA monitoring. The documented SQL interface can be used. For more information, see the document SAP HANA SQL and System Views References linked below. SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company. All rights reserved. 137 Third-Party Tools with Direct Access Alternatively, third-party monitoring tools can access the SAP HANA database directly in order to retrieve and process alerts. Monitoring with SAP Landscape Virtualization Management Another option for monitoring the system status is SAP Landscape Virtualization Management. This makes it possible to monitor running HANA processes and the entire application server as well. Operational activities such as server start and server stop are possible, too. In Enterprise Edition, dashboards can configured which provide a visual overview of all basic activities, such as status of the SAP instances, servers, validations and performance graphics, for example the server’s CPU load. Unlike Enterprise Edition, Standard Edition is license free. 138 © 2015 SAP SE or an SAP affiliate company. All rights reserved.

All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction 1.5.2 Backup and Restore Executive Summary and Key Takeaways ● Plan regular backups of your SAP HANA database. ● You can use a number of strategies and tools to perform your backups. ● Re-importing a backup is known as recovering. ● There are also a number of ways to perform a recovery. ● Security is an important consideration when backing up and recovering data. Database Backup All SAP Business Suite objects are saved in the underlying database. It is therefore important to perform regular backups of your database, to protect the system against data loss. If necessary, you can back up all SAP Business Suite files and subfolders, including configuration files and log files, at operating system level.. The backup and restore concept of the database for your system landscape should not only consider SAP systems. It should be embedded in the overall business requirements and take into account the whole process flow in your company. The backup interval depends on the way the Business Suite is used. For example, you can create a full backup of the database every week. All changes since the last backup (that is, the transaction log of the database) are backed up at more frequent intervals. The interval also depends on how quickly you need to be able to recover a backup. If the number of log backups to be recovered is very high, the time required to perform this recovery increases significantly since more log information needs to be rolled forward. Ensure that the backup files are written to separate devices, to prevent a loss due to hardware failure. You also need to monitor the space at file level to ensure that there is sufficient space for the data backup and the log backup. In addition to backing up the data segment and the log segment, back up the configuration files. After planning and setting up a backup mechanism, we recommend that you test the restore scenario. This ensures that the importing of a backup works correctly. You can create a backup in a number of different ways, using established backup strategies: ● Backup using Scheduling with DBA Cockpit For more information, see DBA Planning Calendar. ● Backup using Shell and SQL Scripting in combination with OS-based Scheduling and hdbsql ● Ad-hoc backup with SAP HANA Studio For more information, see SAP HANA Administration Guide. ● Using the BACK INT interface and third-party tools For more information about certified tools, see SAP Partner Center. Database Copy You can create a homogenous copy of a database by recovering an existing source database backup to a different, but compatible, target database. SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company. All rights reserved. 143 A homogenous database copy is a quick way to set up cloned systems, for example, for training, testing, and development. For this reason, copying a database can significantly reduce total cost of delivery (TCD). Note It is planned to introduce a database cloning feature in SAP Landscape Virtualization Management Software (LVM). Database Recovery It is recommended that you use SAP HANA studio to perform a recovery. We recommend that you create a new full backup at the earliest opportunity after the database recovery. It may be necessary to recover the SAP HANA database in the following situations: ● A disk in the data area is unusable. ● A disk in the log area is unusable. ● As a consequence of a logical error, the database needs to be reset to its state at a particular point in time. ● You want to create a copy of the database. When restoring the database, you first define the recovery variant that you want to use. The system then checks whether all required backup files, including log files, exist. Only once this check has been performed does the system start to recover the database by importing the selected full backup and the log segments. Possible Recovery Types ● Recover the database to its most recent state ● Recover the database to the next point in time ● Recover the database to a specific data backup ● Recover the database to the next log position For more information, see the information section.

Database Copy SAP HANA Administration Guide For more information, see the section Copying a Database Using Backup and Recovery of chapter Backing Up and Recovering the SAP HANA Database in the SAP HANA administration guide. 1.5.2.1 User Authorizations To back up or restore the SAP HANA database, you need specific user authorizations the database level. To perform a backup a recovery, the following authorizations are required: Table 20: Task Type Required Authorization Back To perform backups, you must have the following system priv ileges: ● BACKUP ADMIN or BACKUP OPERATOR ● CATALOG READ This privilege is required collect the information needed by the backup wizard. Recover Open the Backup editor Delete data and log backups from the backup catalog and The recovery process is executed as the operating system user (<sid>adm). You must therefore have the logon creden tials of this user. ● BACKUP ADMIN ● CATALOG READ ● BACKUP ADMIN physically from the backup location. The system privileges BACKUP ADMIN and BACKUP OPERATOR exist so you can implement a finer-grained separation of duties if this is necessary in your organization. A user with the system privilege BACKUP ADMIN can perform all backup-related operations, including backup deletion and configuration. A user with the system privilege BACKUP OPERATOR can only perform backups. SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company. All rights reserved. 145 Example For example, if you have automated the regular performance of backups using on, it is more secure to use a user with the privilege BACKUP OPERATOR to avoid the malicious deletion of backups. 1.5.3 Security Executive Summary and Key Takeaways ● SAP HANA provides a framework and functions that can be used to implement specific security and compliance policies. ● The integration with your security network and data center infrastructures is enabled with standard interface support. ● The security needs of current and future business applications are met with a rich set of authorization mechanisms based on standard SQL privileges and SAP HANA-specific extensions. ● SAP HANA is used in different scenarios that require different security approaches. The architecture of the scenario determines the security approach. The Importance of Security As it becomes increasingly important for organizations to protect their critical data from unauthorized access and to ensure compliance with a growing number of rules and regulations, the demands on security are also increasing. As an in-memory computing platform that supports multiple implementation scenarios and use cases – from traditional relational databases underneath SAP applications to the platform for development and deployment of innovative new applications – SAP HANA can play an important part in critical IT and application infrastructures. It is therefore essential that you integrate SAP HANA into your infrastructure securely and protect your data in SAP HANA. Differences of SAP HANA Security Concept Towards Other SAP Solutions SAP HANA has a very similar concept to other SAP solutions, for example you have roles, users, and authorizations. Therefore the general approach is the same as before and you can continue to use your security strategy. There are differences in the details like what type of authorizations are available and tools. The security requirements and measures heavily depend on the scenario in which the SAP HANA application is operated. When SAP HANA is used as a database of an SAP application, the same security approach applies and specific SAP HANA security features are mainly needed to control access of administrators to the database. 146 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction Security Functions Depending on the scenario in which SAP HANA is used, only some of these functions might actually be needed. Others might be provided in other architecture layers. The security functions overview is illustrated in the graphic below: Table 21: Authentication/SSO SAP HANA offers various authentication methods: ● For SQL access: 1. User name and password (incl. password policy) 2. Kerberos 3. SAML 2.0 ● For HTTP access (via SAP HANA XS): 1. User name and password (incl. password policy) 2. SAP logon tickets 3. SAML 2.0 4.

For logon, users must exist in the identity store of the SAP HANA database ● Roles (and privileges) can be assigned to users. ● Roles are used to bundle and structure privileges. Role hi erarchies are supported. ● Roles can be created in the repository during design time. This makes it possible to export and import roles using repository functions. The user and role management of SAP HANA XS is fully integrated with the core database user and role management. SAP HANA provides a rich set of authorization mechanisms based on standard SQL privileges and SAP HANA-specific ex tensions to meet the needs of current and future business ap plications. All access to data and execution of actions in the database require authorization: Privileges control what users can do. ● System privileges: Authorize execution of administrative actions for the entire SAP HANA database ● SQL privileges: Authorize access to data and operations on database objects ● Analytic privileges: Authorize read access on analytic views at runtime, provide row-level access control based on dimensions of the respective view ● Package privileges: Authorize access in the repository (modeling environment) at design time ● Application privileges: Authorize access to SAP HANA XS application functions SAP HANA can encrypt this persistent storage (the data vol umes on disk), which ensures that users cannot see the actual content even if they can access the data volumes on disk us ing operating system commands. SAP HANA offers various encryption methods ● Communication encryption based on SSL ● Data volume encryption on disk Audit logging tracks actions performed in the database: who did what – or tried to do what – and when. SAP HANA offers logging of critical events for security and compliance. These include ● User, role, and privilege changes ● Configuration changes ● Read and write access (tables, views), execution of pro cedures ● The audit trail written to OS SYSLOG. Audit logging can be configured in the SAP HANA studio or using SQL statements. Audit policies define which actions in the da tabase are logged, such as audit target and audited users. These policies can be configured to the customer’s needs.

The figure below illustrates the security infrastructure of SAP HANA and is followed by an explanation: ● Identity management (user and role provisioning) ○ SQL-based interface for user and role creation ○ Out-of-the-box connector for SAP Identity Management is available ● Compliance infrastructure ○ Out-of the box connector for SAP Access Control is available ● Standard-based single sign-on infrastructures based on Kerberos, for example Microsoft Active Directory SAML ● Logging and monitoring infrastructures ○ Database audit trail written to Linux syslog Operating System SAP HANA comes with SE Linux Enterprise (SLES) 11 pre-installed and preconfigured. is already includes preconfigured security settings, such as minimal network services running. To conform with internal and external IT policies, customers n make certain changes or additions to the standard SAP HANA appliance installation. The details are described in SAP Notes. 150 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction Security Patches SAP HANA security patch information is published as part of the general SAP security patch strategy (SAP Security Notes). SAP HANA security patches are delivered as SAP HANA revisions and can be applied using the Software Update Manager for SAP HANA. Operating system security patches are provided and published by SUSE. Network Recommendation It is recommended that you operate the SAP HANA appliance in separate network zones. Recommendation To prevent unauthorized access to the SAP HANA appliance and the SAP HANA database through the network, we recommend the application of network firewall technology to create network zones for the different components and to restrictively filter the traffic between these zones implementing a minimum required communication approach. The network communication channels, such as purpose and ports, used by SAP HANA are documented in detail in the SAP HANA master guide. The SAP HANA security guide includes recommendations on the use of firewalls, for example to separate internal and external communication as well as the options for encryption using SSL. A reference for the SAP HANA network protocol is also available. Compliance Infrastructure Compliance plays an important role in many customer environments. SAP HANA provides functions that support customers in achieving compliance. Compliance in most cases is not a product feature, but depends on many factors such as: ● Relevant rules and regulations such as IT policies, industry, and country ● Existing technology and infrastructure, processes, and audit approach To achieve compliance, usually both process and functional requirements need to be fulfilled: ● Best practices in security operations ● Need-to-know principle, separation of duties all levels ● Control of privileged access ● Ability to audit ● Deletion of data SAP HANA takes an end-to-end approach to enable application compliance, the basis for which is provided by the built-in database security features and the security options of the whole software and hardware stack. This is extended by the integration of SAP HANA into existing security infrastructures through standard or documented SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company.

It n serve as the database for SAP Business Suite applications, and it n serve as the database for SAP HANA Live analytics for SAP Business Suite. When being used for SAP HANA Live, the database can be shared with the SAP Business Suite application ith ittle or no data replication, or it can be installed in a sidecar manner, where data is replicated from the SAP Business Suite system to a separate SAP HANA database for SAP HANA Live. SAP HANA as Database for SAP Business Suite In this architecture, a three-tier application, security management features such as authentication, authorization, encryption, and audit logging are located and enforced mostly in the application server layer, while the database is used only as the data store Applications connect to the database through a technical user account, and direct access to the database is only possible for database administrators. End users do not have direct access to either the database itself or the database server on which it is running. As a consequence, security in the database layer is mainly focused on securing administrative access to the database. For access from SAP Business Suite: ● The same security model as with other databases applies for user access. ● Security functions of SAP NetWeaver ABAP or SAP NetWeaver JAVA still apply. ○ Application server connects with technical database user to SAP HANA database ○ Authorization management is as before with existing methods ○ User management is performed in the application server ● SAP HANA security functions are used to manage administrative access to the database. 152 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction The concept described above is illustrated in the following figure: SAP HANA Live for SAP Business Suite Individual users directly access the SAP HANA database sing the SQL protocol, for example to consume reports, view dashboards, or to use SAP BusinessObjects Business Intelligence solutions. Therefore, all security functions of SAP HANA, for example, for user management, authentication, privilege management and authorization check, encryption of communication channels and of data, and security logging, are used to secure access. SAP HANA Live for SAP Business Suite supports direct access to SAP ERP data in SAP HANA. ● ERP data is exposed through analytical views as rtual data models. ○ Virtual data models can be used by the customer to create new views. ○ Virtual data models can be exposed, for example through SQL or TP, and consumed by different clients, such as the browseror reporting tools. ○ SAP HANA Live can be used in a sidecar approach using replicated data or in an integrated approach. ● Each SAP HANA Live user gets a database user. ● Authorization check occurs within SAP HANA using privileges. ● Creation of SAP HANA authorizations can use a tool that allows the creation of authorizations directly in the SAP HANA tudio based on the ABAP roles already defined in the profile generator of SAP Business Suite (transaction code PFCG). ○ Analytics Authorization Assistant SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company.

Will all existing SAP Business Suite ABAP users e migrated with the correct authorizations after an SAP HANA tabase migration Absolutely – The migration of an SAP ERP database to SAP HANA is a full database migration. Will the user administration in SAP ERP on SAP HANA change and how does this impact our security team? All SAP ERP users and roles are defined through the SAP ERP application layer. The only change is for the users of the SAP HANA data modeling studio in the SAP HANA data mart, and his also applies to SAP HANA Live. Recommendation recommend that you train the security team in SAP HANA. There are specific technical training urses available. Is the authorization for SAP HANA Live re similar to the SAP ERP on SAP HANA security model or to the SAP HANA data mart security model? 154 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction The user privileges in the SAP HANA security model are currently less granular than authorizations in the application layers for SAP BW powered by SAP HANA and for SAP Business Suite powered by SAP HANA. For SAP HANA Live, the SAP HANA-based analytical privileges are used with each analytics user becoming a database user. The privileges of the database user are then verified when accessing SAP HANA Live objects. Does SAP provide a tool to migrate SAP Business Suite application users' privileges to SAP HANA Live authorizations? The SAP HANA Live Authorization Assistant provides an authorization tool that generates analytic privileges and corresponding roles of the selected SAP ABAP user. The assistant is available as an Eclipse plug-in for the SAP HANA udio. The assistant reduces manual effort sing a semi-automated generation, which the users’ SAP ABAP authorizations are transformed to SAP HANA analytic privileges. For more information, see the information section.

Porting your SAP Business Suite system to SAP HANA means first itching to In-Memory DB, which improves database times. With the optimization of SAP Business Suite powered by SAP HANA you want to use the full potential of the SAP HANA platform innovations. The starting point of the optimization is to consistently optimize your ABAP custom code. Open SQL is compatible with AnyDB and is used to optimize existing queries without any additional operation impact. With views and Native SQL you use native SAP HANA functionality to optimize data access. Stored procedures allow you to push SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company. All rights reserved. 155 down business application logic from the SAP Business Suite application layer into the SAP HANA database. Using stored procedures, parallelized queries, and advanced view modeling results in: ● Improvement of database and application times ● ewer lines of code ● Reduced data traffic between layers ● Less main memory required for the application The section Code Migration and Optimization, linked in the information section, describes the steps that are required to optimize the custom code from the execution of the code assessment to the classified ABC worklist of the prioritized technical objects and the execution of the code optimization. The main goal is to speed up dedicated transactions and to reduce the overall cycle time of the core business processes. Redesign and Optimization of Business Processes SAP HANA enables you to execute Online Analytical Processing (OLAP) and Online Transactional Processing (OLTP) on one platform and therefore opens the door for new individual business processes on your SAP Business Suite system. There is no need for data duplication, data aggregation, or index programming anymore. For example, SAP HANA Live provides you with the semantic layer of a Virtual Data Model (VDM) to run analytics in realime. From insight to action means that, based on real-time reporting and analysis executed directly in-memory, you can execute transactions in realime. With SAP HANA your processes gain agility, you can think about real-time planning, realtime simulation, and real-time interactions. Optimizing SAP Business Suite powered by SAP HANA brings value for IT, business, and people and requires the involvement of fferent parties. SAP Business Transformation Services (BTS) and services of SAP Active Global Support can help you to leverage the full the potential of SAP HANA. The following table shows some examples of how SAP HANA can be used to optimize your business processes. You can, for example, blur the boundaries between OLAP and OLTP, replace batch processes, and go without aggregation and index programming.

This is the only way to synchronously execute changes that affect more than one production system. If you use SAP HANA application-specific accelerators like CO-PA for example, in combination with your SAP ERP back end, you might need to synchronize changes to the data models on SAP HANA with changes for accessing the changed models from transactions on SAP ERP. SAP Solution Manager provides central transport functions for the entire system landscape and additional support for quality management. The graphic below illustrates the process of transporting changes and is followed by an explanation: The process for transporting changes from a SAP HANA development system to a quality assurance and o the productive system starts in SAP HANA Studio. You retrieve content from the SAP HANA source system there and export it to enhanced Change and Transport System (CTS+) in SAP Solution Manager. The exported delivery units are automatically attached to a transport request of CTS+. Once you have released this transport request, 158 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction CTS+ triggers the automatic activation of the change in the SAP HANA repository on the target system, such as quality assurance or production. As well as supporting the transport and activation of new or changed data models, views, stored procedures, or analytic privileges, SAP Solution Manager offers additional possibilities for improving the quality of changes. You can use change analysis and reporting to obtain information about the current status and history of changes. Configuration validation checks if the systems of your system landscape, such as development, quality assurance, and production, are configured consistently and in accordance with the requirements. Quality Gate Management provides an additional quality inspection for projects and ensures that changes are transported correctly and synchronously to the production systems. Change Request Management within SAP Solution Manager controls the entire change execution with detailed process and workflow control. From these options, you can select the ones for controlling changes on SAP HANA that are best suited to your organization's quality strategy. CTS is the standard Change and Transport System for SAP ABAP systems. SAP HANA repository content can be packaged within delivery units. These delivery units can be captured insides and ABAP transport object, called SAP HANA transport container. These SAP HANA transport containers can be transported via the standard ABAP CTS. Transport Scenarios for SAP HANA There are a number of different transport scenarios for SAP HANA content, depending on how SAP HANA content is used. You can use the HANA Transport Container (HTC) to transport SAP HANA content for ABAP for SAP HANA applications. Otherwise, you can use the enhanced Change and Transport System or SAP HANA Application Lifecycle Management to transport SAP HANA content for native SAP HANA applications. SAP HANA content refers to SAP HANA development objects that are created in SAP HANA-based development projects. SAP HANA content is not part of the SAP HANA database installation itself. It is stored in the repository of the SAP HANA appliance software and can include different objects, such as schemas and table definitions, information views (attribute views and analysis views), SQL scripts, or roles and authorizations. A typical system landscape for SAP HANA development consists of a development system, a quality assurance system, and a production system. To transport SAP HANA development objects from a system to a successor system, there are a number of transport scenarios available. The transport scenario that is suitable for your situation depends on the way the SAP HANA content is used that you want to be transported, and on your system landscape. SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company. All rights reserved. 159 The concept described above is depicted in the following figure: Native SAP HANA Content Content for native SAP HANA applications is SAP HANA content that is developed exclusively for SAP HANA systems. You can use the enhanced Change and Transport System (CTS+) to transport SAP HANA content for native SAP HANA applications, or for non-ABAP applications that are based on SAP HANA. It is particularly wellsuited to heterogeneous transport landscapes in which CTS+ is already in use. From an administrative point of view, the SAP HANA content is another object type that can be transported with the CTS in the same way as other non-ABAP objects. The effort required for configuration is low, and the transport tools are already familiar. In particular, you can use CTS+ if you want to transport SAP HANA content as part of an SAP solution (such as SAP BI, Mobile, and so on), since in this case, you often need to create a link between the SAP HANA content and other non-ABAP development objects and non-HANA development objects. This transport scenario is integrated into the existing CTS transport landscape and into the SAP tools for change control (Change Request Management and Quality Gate Management of the SAP Solution Manager) the transport is performed in the same way as for any other non-ABAP application that is integrated into CTS+. SAP HANA Content for Native SAP HANA Applications If CTS+ is not in use, you can use SAP HANA Application Lifecycle Management to transport SAP HANA content for native SAP HANA applications. You can use SAP HANA Application Lifecycle Management to perform transports and monitor transport processes. SAP HANA Application Lifecycle Management is particularly well-suited to SAP HANA transport landscapes with no ABAP development (without CTS+) and with no requirement for synchronizing transports with other nonHANA content. 160 © 2015 SAP SE or an SAP affiliate company. All rights reserved. SAP Business Suite powered by SAP HANA Cookbook Introduction SAP HANA Content for ABAP for SAP HANA Applications SAP HANA content for ABAP for SAP HANA applications is usually transported together with ABAP objects because the development objects are closely-connected in terms of content. You can use the HANA Transport Container (HTC) to transport this SAP HANA content. The HTC is a logical transport object that is transported with the standard ABAP transport tools. An HTC always contains all SAP HANA repository objects of a delivery unit. The HTC is attached to a standard ABAP-transport request and transported together with the associated ABAP objects. When the transport request is imported into the target system: ● The ABAP objects in the transport request (including the HTC) are imported into the ABAP system. ● The SAP HANA repository objects in the DU are imported into the SAP HANA repository. The import is performed with or without activation, depending on the system settings of the associated ABAP software component of the HTC. This transport scenario is integrated into the existing CTS transport landscape and into the SAP tools for change control (Change Request Management and Quality Gate Management of the SAP Solution Manager). SAP HANA Lifecycle Management and SAP HANA XS Starting with SAP HANA SPS 6, SAP HANA introduced Application Lifecycle Manager (ALM). This new tool is made available with SAP HANA udio. It enables you to manage, replicate, and transport SAP HANA development components. SAP HANA ALM is an XS application automatically installed as part of the SAP HANA database server. A document offering a full comparison of ALM and CTS+ can be found here: HANA Application Lifecycle Management Setup & How It Compares to SAP CTS+ Integration Additionally, SAP HANA XS can be used to transport components directly between SAP HANA systems by using a tool called XS Lifecycle Manager (HLM). The following points provide you with guidelines on the best way to transport and manage content between systems or your specific situation: ● You should use CTS+ when: ○ Your SAP environment is made up of many SAP systems and you have an established change process around ABAP transports ○ Your SAP environment already includes CTS+ for transporting non-ABAP related objects such as Portal, PI, or SLD ○ Your SAP changes are managed by SAP Solution Manager Change Request Management (ChaRM) ● You should use CTS when: ○ You expect your SAP HANA content to be managed by a separate dedicated group of people who have no responsibility or knowledge of your other SAP systems ○ Your landscape does not have other SAP systems (ABAP or Java). ○ Your SAP landscape has many ABAP systems but you do not have any Java systems for implementation of CTS+ SAP Business Suite powered by SAP HANA Cookbook Introduction © 2015 SAP SE or an SAP affiliate company.
