Task & functionality of the SAP authorization concept
Query Data from Active Directory
The SAP administrator uses the concept to assign users their dedicated authorizations. Behind these is a checking mechanism based on so-called authorization objects, by which the objects or transactions are protected. An authorization object can comprise up to ten authorization fields. This allows complex authorization checks that are bound to several conditions.
When scheduling a job, another user can be stored as the executing user. This means that the individual processing steps of the job are technically carried out by the stored user with his or her authorizations. This means that activities could be triggered that could not be executed with the user's own authorizations.
Integrate S_TABU_NAM into a Permission Concept
If you want to allow users to access only individual table rows, you can use the S_TABU_LIN authorization object, which allows access to specific rows of a table for defined organisational criteria. A prerequisite for this type of permission is that the tables have columns with such organisational values, such as the work, country, accounting area, etc. You must now configure these organisational values in the system as organisational criteria that represent business areas; serve as a bridge between the organisational columns in the tables and the permission field in the authorization object. Since the organisational criteria are found in several tables, this eligibility check need not be bound to specific tables and can be defined across tables.
The call to your implementation of the BAdIs is the last step in the process of storing user data. This applies to all transactions or function blocks that make changes to user data. Therefore, the BAdI is also called during maintenance by the BAPI BAPI_USER_CHANGE. You use this BAPI when you implement a password reset self-service as described in Tip 52, "Reset Passwords by Self-Service." This enables encrypted e-mail delivery of initial passwords within a self-service framework.
During go-live, the assignment of necessary authorizations is particularly time-critical. The "Shortcut for SAP systems" application provides functions for this purpose, so that the go-live does not get bogged down because of missing authorizations.
In this context, we recommend that you check the mappings for critical function blocks or functional groups.
The AIS system audit covers general system audits and analysis of users and permissions.
