With user administration, you create a user master record for each user, with which the users can log on to SAP NetWeaver Application Server for ABAP (SAP NetWeaver Application Server for ABAP). Assign one or more roles to the user master record, to define the activities and authorizations that the user is expected to perform.
User master records are client-specific. Maintain separate user master records for each client in the SAP system. To simplify cross-client user administration, use central user administration (CUA). Maintaining users with CUA is slightly different from user administration without CUA.
You cannot transport user master records. Instead, copy them using a client copy or use central user administration to distribute the user master records from the central system to the child systems.
The user administration tool (transaction SU01) and related transactions, such as mass maintenance (transaction SU10), are described in the sections that follow.
