Authorization roles (transaction PFCG)
In addition to SAP book recommendations on SAP authorizations, I can also recommend the books from Espresso Tutorials such as "SAP Authorizations for Users and Beginners" by Andreas Prieß * or also the video tutorial "SAP Authorizations Basics - Techniques and Best Practices for More Security in SAP" by Tobias Harmes. Both are, among other media, also included in the Espresso Tutorials Flatrate, which I have also presented in more detail under SAP Know How.
Create a function block in the Customer Name Room. You can choose the supplied SAMPLE_INTERFACE_00001650 as the template. For us, it has proven itself, in the name of the new function block, the name BTE and the number of the template (here: 1650).

You can use authorization objects to restrict access to tables or their content through transactions, such as SE16 or SM30. The S_TABU_DIS authorization object allows you to grant access to tables associated with specific table permission groups. You can view, maintain, and assign table permission groups in transaction SE54 (see Tip 55, "Maintain table permission groups"). For example, if an administrator should have access to user management tables, check the permission status using the SE54 transaction. You will notice that all the user management tables are assigned to the SC table permission group.
The case that the user buffer is not up to date is very rare. The auth/new_buffering profile parameter sets the value 4 to immediately update the permissions, i.e. changes to the user root or roles or profiles, and write them to the USRBF2 database table without requiring a new login. This value is set by default. The fact that the buffer is not up-to-date is recognised by the fact that existing permissions that are not in the buffer are marked in the transaction SU56 with the note "In the root data but not in the user buffer".
"Shortcut for SAP systems" is a tool that enables the assignment of authorizations even if the IdM system fails.
This fix extends the naming conventions so that namespaces in the /XYZ/ format can be used up to a maximum of eight characters.
In addition, the SAP Cryptographic Library must be installed; but this is ensured by the required kernel patch.
