Full verification of user group permissions when creating the user
In SAP systems, authorization structures grow over the years. If, for example, there is a restructuring in the company or there are new organizations, there is a risk that the authorization concept no longer fits or is implemented correctly.
Create a message to be displayed to the user when permissions checks fail. The tests in this User-Exit are relatively free. This allows you to read table entries, store data from the ABAP application's memory, or read data that is already there. However, you are limited by the interface parameters of the application. In our example, these are the BKPF and BSEG structures and the system variables. If the information from the interface parameters is not sufficient for the test, you can use your programming skills and knowledge about the interdependencies of substitution and validation in finance to find additional data. The following coding allows you to identify the selected offset document entries that you can find in the POSTAB table (with the RFOPS structure) in the SAPMF05A programme. This way you can find many additional data. It is important that the supporting programme processes the User-Exits.
Controlling file access permissions
For performance reasons, the SAP kernel checks whether a user is authorised in the permission buffer. However, only profiles and no roles are loaded into the permission buffer. Calling the SU56 transaction will cause you to parse the permission buffer, first displaying your own user's permission buffer. A pop-up window to change the user or authorization object will appear from the Other User/Permissions Object (F5) menu path. Here you can select the user you want to analyse in the corresponding field. The Permissions > Reset User Buffer path allows you to reload the permission buffer for the displayed user.
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.
