2 Architecture of MOLAP Aggregates in BW 3.0
... Figure 3 shows the situation for MOLAP aggregates. In BW 3.0, InfoCubes have aggregates that are either based on the ROLAP or on the MOLAP scenario. Mixed scenarios are not possible. However, it is fairly easy (but not necessarily fast – this depends on the associated data volumes) to switch between ...
