Constraints in DBMS User Management

SAP HANA

SAP HANA and SAP NetWeaver Application Server for ABAP support different character sets for user IDs. For more information about characters supported by SAP HANA, see the documentation for SAP HANA.

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.
