System trace function ST01
SAP S/4HANA® Launch Pack for Authorizations
If an entry in transaction SE97 is correctly created, a permission check is performed in the same way as a transaction startup authorisation. This approach therefore requires an exact and complete configuration for each transaction that is invoked. The required effort and the space for errors are correspondingly large. The CALL TRANSACTION ABAP command does not cause a transaction startup permission check. Without a permission check, the ABAP programme could unintentionally allow users to access system resources. In many cases, such authorisation problems lead to a hidden compliance violation, because this means that the traceability of user actions in the SAP system is no longer guaranteed. A developer should not rely on the functionality of the SE97 transaction and therefore should include the possible permission checks in the code. Therefore, one of the following explicitly coded permission checks for the CALL TRANSACTION statement must be performed.
Add missing modification flags in SU24 data: This function complements the modification flag for entries that have changed since the last execution of step 2a in the transaction SU25, i.e., where there is a difference to the SAP data from the transaction SU22. The flag is thus set retrospectively, so that no customer data is accidentally overwritten with step 2a due to missing modification flags.
What are the advantages of SAP authorizations?
Protect your system from unauthorised calls to RFC function blocks from the S_RFC authorization object by obtaining the necessary permissions using the statistical usage data. In many organisations, the primary focus in the permission environment is on protecting dialogue access. For each required transaction, you decide in detail which groups of people are allowed access. It is often overlooked that the critical S_RFC privilege object requires an analogue permission assignment. If the RFC (Remote Function Call) external access permissions are unneatly defined and assigned to the users, the S_TCODE authorization object quickly bypasses the primary protection for bootable applications.

SAP_AUDITOR_TAX Collector Role: The SAP_AUDITOR_TAX collection role is made up of module-specific individual rolls and can be seen as a proposal for the read-only role of the tax inspectors (see SAP Note 445148 for details on this role). The transactions and reports included in the SAP_AUDITOR_TAX collection role have been expanded to include additional checks that define the audit period. Some of the transactions and reports included in the SAP_AUDITOR_TAX collection role have also been expanded to include a logging of the call parameters to allow the taxpayer to better understand the auditor's audit trades.
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".
The role definition reflects an interpretation of the DSAG of the concept of tax-relevant data.
The freeware Scribble Papers puts an end to the confusing paper chaos. The tool is also suitable for storing, structuring and quickly finding text documents and text snippets of all kinds in addition to notes.
