Introduction & Best Practices
When creating the PFCG individual roles in the respective SAP system, you should create the menu structure so that they can be combined with other individual roles in a single role. Once you have created the individual roles with the correct role menu, you can assign them to a collection role. Add the Role Menu to the Collect Roll using the Read Menu button. The menu can now be finally sorted. If changes to the roll menu are necessary, however, you must first make them in the individual rolls and then remix them in the roll roll (using the Mix button, see figure next page above). Transactions from other SAP systems such as SAP CRM, SAP SCM etc. can also be integrated into the NWBC. To do this, you first create the PFCG role for the relevant transactions in the target system. From the individual roles you can create collection roles with a defined menu structure.
If you do not have authorization e.g. for a transaction and you get a message that you are missing authorization, you can use transaction SU53 to analyze the missing authorization. This transaction shows the last failed authorization check, including the authorization objects and authorization fields.

The chapter on authorization recertification should also be defined in the authorization concept, which is documented in writing. This refers to a regular review of the assigned authorizations in the SAP® system, to be performed at least once a year. In the course of this process, the responsible departments should review the assignment of the respective roles to users in their area and critically scrutinize it once again. This process ultimately ensures that users only have the authorizations in the SAP® system that they actually need. It must therefore be defined in which time period and in which form the departments must receive the information about the assigned authorizations and report back regarding the correctness of the assignment. During preparation, it is therefore necessary to check whether the process has been carried out in accordance with the internal specifications, but also in accordance with possible suggestions for optimization made by the auditor, and whether all the evidence is stored ready to hand for the auditor.
It is essential to implement adequate authorization checks in every ABAP development. For this purpose, the so-called AUTHORITY-CHECK is used, which queries the required authorization object characteristics and thus only allows authorized users to execute the code.
"Shortcut for SAP systems" is a tool that enables the assignment of authorizations even if the IdM system fails.
So it is better to let the user himself display the authorization error via the menu.

Another option is to not assign the SAP_NEW permission to a user.
