Note the maintenance status of permissions in roles and their impact
Run step 2a (automatic synchronisation with SU22 data). In this step, the data of the transaction SU22 of the new release will be transferred to the transaction SU24. If there is a change or difference in applications (changed check marks, suggestions, field values, or new or deleted authorization objects), the USOB_MOD or TCODE_MOD table of the MOD_TYPE is set to M. With SAP Note 1759777, a selection is offered for step 2a, with which this step can be simulated. Another option, Delete Flags for applications with modified data, is offered to apply the new changes only if Step 2a is executed selectively.
Unlike the EWA, the SOS is able to list users that require extensive permissions. So you can maintain a whitelist. We recommend that you deal with the results of the SOS as follows: Verify that all identified users require critical permission. Complete the users who need this permission in the whitelist. Remove this permission from other users.
Use usage data for role definition
Here, too, it is possible to create security and an overview with the help of tools for HR authorizations. The tool creates a clear overview of which data certain users are allowed to access in the SAP system. Based on this, it is possible to develop automatic checks that run in the background and regularly monitor whether changes to authorizations have created critical gaps in HR.
Numbers/reminders: The payment and/or collection procedure shall be managed solely on the basis of information from the collection perspective (in particular Table BSEG). For customer and vendor transactions, the Profit Centre is not included in the SAP journal masks by default, and is therefore not available on the appropriate BSEG document lines. Since numbers and warnings are usually centrally controlled processes, this should not be a problem in practice.
However, if your Identity Management system is currently not available or the approval path is interrupted, you can still assign urgently needed authorizations with "Shortcut for SAP systems".
SAP Note 1707841 ships an extension to the system trace in the STAUTHTRACE transaction, which enables the permission trace to be used on all or on specific application servers.
As already mentioned, these are mostly based on the SAP modules.
