The role concept provides that each user can only process the tasks to which he is authorized. It is developed across departments and must protect sensitive data from unauthorized access. A clear role concept enables a modular structure of authorizations without having to create separate roles for each user.
The ABAP authorization concept protects transactions, programs and services in SAP systems against unauthorized access. Based on the authorization concept, the administrator assigns authorizations to users that determine which actions a user is allowed to perform in the SAP system after logging on to the system and being authenticated.
You should archive all document types at the same time intervals; This is especially true for the US_USER and US_PASS archive objects. It is customary to keep the supporting documents between 12 and 18 months, as this corresponds to the retention periods for the revision. For performance reasons, if you want to archive in shorter intervals, you should always archive all archive objects at the same time and store the PFCG and IDENTITY archive object classes in separate archives. In this case, it may be useful to download the archived revision documents back to a shadow database to make them available for faster review. You can use the following reports: RSUSR_LOAD_FROM_ARCH_PROF_AUTH / RSUSR_LOAD_FROM_ARCHIVE. You can also archive the table change logs with the BC_DBLOGS archive object.
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.
With "Shortcut for SAP systems" you can automate the assignment of roles after a go-live.
