Identity Management 
The Identity Management InfoArea contains the content to use for reporting with SAP NetWeaver Identity Management. You can use the provided queries (or create your own) to find out information about your users and their assigned roles and privileges and which systems they have (or have had) access to in the SAP NetWeaver Identity Management landscape. This information can be made available for obtaining status reports in your system, including the history of users and their role, privilege, or system assignments.
SAP NetWeaver Identity Management uses a Web service to load the identity data from its database to the SAP Business Warehouse system. Therefore, to be able to use SAP NetWeaver Business Warehouse for identity management reporting, you must first set up the integration between the two systems and initiate the data transfer. For more information, see the document Identity Reporting Using SAP NetWeaver Business Warehouse.
