Handle the default users and their initial passwords
Analysis and reporting tool for SAP SuccessFactors ensures order and overview
The first step in the cleanup process is therefore to find out whether the current authorization concept is sufficient and a cleanup is the best way forward, or whether a rebuild of the authorization concept is necessary. The focus should be on saving the current authorization concept, since rebuilding it takes more time than cleaning it up.

For accesses by verifier users (from the table TPCUSERN), the selection parameters of the invoked transaction are logged in the application log and can be evaluated with the report CA_TAXLOG. In the example, the single ledger entry for the vendor account 100000 was invoked.
Law-critical authorizations
One way of gaining direct access to downstream systems from the development system and possibly performing unauthorized activities there is to use incorrectly configured interfaces. In principle, interfaces within a transport landscape should be avoided with regard to the criticality of the systems "uphill", i.e. from an "unsafe" to a "safe" system (e.g. E system to Q or P system). However, this cannot always be implemented; for example, such interfaces are needed within the transportation system. Without going too deeply into the subject, however, critical interfaces can be characterized by the following properties. Critical interfaces refer to a critical system and a critical client, contain an interface user with critical authorizations in the target client, contain its deposited password.

If you have defined the roles to the extent that the essential processes are depicted, then you will technically check which organisational features they contain (organisational levels, but also cost centres, organisational units, etc.). You then compare the technical result with the result from the consideration of the structure organisation and the business role description. A likely result is that you do not have to use all technical organisational features for differentiation. A possible result is that you want to add fields such as the cost centre to the organisation level.

If you get into the situation that authorizations are required that were not considered in the role concept, "Shortcut for SAP systems" allows you to assign the complete authorization for the respective authorization object.

Since RFC interfaces are defined for the entire system, they can be used from any client of the start system.

DDIC exists in all clients except 066.
