OneAccess central data store is used to synchronize, transform, and distribute information across all the SAP systems. When user access request is created in OneAccess, the UserManager detects and propagates these changes to other connected systems based on the business rules you define. This solution enables you to enforce authoritative approver for any particular piece of data. One Access UserManager achieves this integration through a unidirectional framework allows to specify which data flows from the OneAccess to the SAP systems.
