How to analyze roles and authorizations in the SAP system
The SAP authorization concept
Customer and vendor totals statements: The Customer or Vendor Accounting Sum. Rate Tables (KNC1/KNC3 or LFC1/LFC3) do not include the Profit Centre field. Therefore, authorisation control with regard to the profit centre is not possible for evaluations such as the customer and vendor balance lists (transactions FD10N or FK10N).
For the entries in the SPTH table, note that the application defines whether a file is accessed with or without the path. For example, the related transactions ST11 (error log files) and AL11 (SAP directories) behave differently. While ST11 opens almost all files without a path (they are in the DIR_HOME directory anyway), AL11 basically uses fully specified file names with a path. An entry in the SPTH table with PATH = / is therefore misleading. It specifies that the defined access restrictions apply to all files specified by path. However, this only applies to applications that access files using a specified path. However, applications that access files without a path are not restricted; Files in the DIR_HOME directory may be excluded.
Criticality
Reasons for incorrect organisational levels are values that have been manually maintained in the authorization object itself, instead of using the Origen button, as well as incorrect transports or incorrectly created or deleted organisational levels. Since correct inheritance can no longer occur in such cases, you need a way to reset incorrect values of the organisation levels in the PFCG roles.
Careful preparation is a prerequisite for a successful authorisation check. A functional specification must be created for all customer-specific functionalities. This forces us to think about what the actual requirements of the application are and then describe the possible implementation. In doing so, security-related aspects, such as eligibility testing and allocation, must be taken into account. Define what you can do with this programme and also what you cannot do explicitly! In the case of a permission check, not only the activity to be performed, such as reading, changing, creating, etc. , can be checked. You can also restrict access to records by using specific criteria, such as field content or organisational separators.
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".
Standard permissions required for a functionally fully descriptive role should be maintained accordingly.
