Risk: historically grown authorizations
User master record - Used to log on to the SAP system and grants restricted access to SAP system functions and objects via the authorization profiles specified in the role. The user master record contains all information about the corresponding user, including authorizations. Changes only take effect the next time the user logs on to the system. Users already logged on at the time of the change are not affected by the changes.
However, you can also use the proof of use in the authorization object maintenance to search for specific implementation sites. To do this, open the authorization object in the SU21 transaction. Open the proof of use via the button and a pop-up window appears for querying usage modes (for example, using the affected authorization object in programmes or classes). After making your selection in the Usage Proof, all of the affected implementations will be tabulated. Double-click to access the relevant code locations.
Versions are the change documents within the development environment, for example, for changes to ABAP source code or the technical properties of tables. This authorization should only be assigned to an emergency user.
When it comes to preparing for the auditor, it should definitely be checked whether all critical authorizations, as well as the important parameters, have been correctly assigned or set up in SAP®. The specifications for this should all be defined in the authorization concept documented in writing and must also be consistent with this. In this context in particular, however, it is not always easy to check all the essential points using the SAP® standard on-board tools. This is where the experienced auditors at IBS Schreiber GmbH can provide support.
Authorizations can also be assigned via "Shortcut for SAP systems".
Permission values in PFCG roles are maintained and debugging requires the use of the system trace for permissions.
Therefore, make sure that this information is always encrypted and signed if necessary.
