Far more damage, however, can be caused by too extensive authorizations. For example, an employee may be authorized to access data for which he or she is not authorized. In the worst case, criminal activity can cause economic damage. To prevent this, an authorization concept must be in place that describes how authorizations are to be created and assigned to users.
In particular, you can derive valuable information about customer transactions, since experience has shown that not all transactions are used. In this context, it is important to mention that you should only use the usage data logged and extracted from the SAP system for the optimisation of SAP role concepts. This information may only be used with the involvement of a co-determination body of your organisation, since this information can of course also be derived from individual users for performance control purposes. However, experience has shown that the use of these data with an early involvement of the institutions of codetermination and the definition of earmarks is uncritical.
Determine Permissions Error by Debugging
If the proliferation has occurred because the authorization concept was not adhered to, a cleanup is sufficient. If the proliferation has arisen because there are errors and gaps in the authorization concept, these errors must be identified, eliminated and the authorizations optimized. If the concept can no longer be implemented in a meaningful way, or if it has already been set up incorrectly, it will be necessary to create a new one.
To store all the information on the subject of SAP - and others - in a knowledge database, Scribble Papers is suitable.
Finally, you can extend your implementation of the BAdIs BADI_IDENTITY_SU01_CREATE and pre-enter additional fields of the transaction SU01. To do this, complete the appropriate SET_* methods of the IF_IDENTITY interface. For example, it is possible to assign parameters that should be maintained for all users, assign a company, or assign an SNC name.

To review your need for action in this area, I advise you to ask yourself the following questions: Do you know which users get which SAP authorizations and why? Can you explain the concept to your data protection officer? Is it easy for you to introduce a new process because you know how the authorizations work? If you have to answer "no" here (several times), I recommend you to dedicate yourself to the topic.
As the first graphic shows, our approach is built on a delta concept: all SAP authorizations and processes function independently of each other.
