user master record
A user master record must exist before a user can log on to an AS ABAP. The record defines which actions a user with a certain user name is allowed to execute and which authorizations he or she possesses. Default settings, such as the way in which decimal separators are displayed in lists, are also defined in the user master record. User master records are edited in transaction code SU01.
