Constraints in DBMS User ManagementLocate this document in the navigation structure

Different DBMS have different constraints.


SAP HANA only supports a subset of the characters for user ID that SAP NetWeaver Application Server ABAP supports.

  • Uppercase letters (A-Z)

  • Numbers (0-9)

  • Underscore (_)

You can only add a remove system privileges for privileges that were assigned by the user configured for the database connection. If you try to remove system privileges assigned by a different user, there is no error message. Although the privilege appears to be removed, the next time you view the user in User Management (transaction SU01), the privilege is still assigned. Exception is repository roles, which are always assigned by the user _SYS_REPO. If you have the required privileges you can remove repository roles.
