All processes of the SAP System are based on the user concept. A user can only log on to the system if a user master record with a password has been defined. To ensure the integrity of the business data in the SAP System, you can set up authorizations for transactions and restrict access to certain data. In the user master, you define and restrict the rights each user has in the SAP System.

The SAPoffice functions (Business Workplace) are automatically available to each user created in the system (the inbox, for example, and so on).
