The purpose of this system is to allow users to import external data from a
payer and loaded into the system. Upon Implementation of a contact,
payments are scheduled and tracking is initiated. This system eliminates
overpayments and compliance exposure by the rebate management processes,
from setting up rebate programs on a contract and calculating and managing
rebates as they accrue, to effecting accurate and timely payments to
eligible customers. The main aim of the project is to deliver and transform
the data that is extracted from various source systems and to load the data
into Sankyo data marts.
