Betting on implementing the ABAP-based Central User Administration (CUA) tool today, is going to lead you down a dead-end road. For all new functionality and all additional applications that are currently in development at SAP, the strategic investment of SAP goes to functionality related to the SAP NetWeaver Identity Management product and not to development projects around the CUA. SAP NetWeaver Identity Management is the tool that leverages modern technology; it is high performing, innovative and scalable.

If you plan to implement a tool to centrally manage user data and access rights in your entire system landscape, do not even look at CUA anymore. If you are uncertain about the replacement of your existing SAP CUA with SAP NetWeaver ID Mgmt, when to do it, or whether and how you should start with the implementation of SAP NetWeaver ID Mgmt at all, contact SAP consulting services. If you are not sure about the migration path or the efforts for internal/external consulting or the timeline for an implementation, you should also talk to the SAP consulting services team.
By the way: this blog is not meant to invalidate CUA will never die (see CUA will never die ) where I said: “CUA Will Never Die”. Both stay true: CUA will be supported according to the normal release and support cycles AND there is not going to be any future investment in CUA functionality in the future. This will also mean that there is not going to be any CUA functionality available for all not-SAP NetWeaver related technology platforms that SAP may build, support or acquire in the future, including SAP Business By Design and any SAP Business Objects or Sybase related products.
