SAP authorizations: Recommendations for setting up, monitoring and controlling
Authorization concept - user administration process
All external services for cross-navigation are stored in the role menu in the GENERIC_OP_LINKS folder. In addition to this information, this folder also contains external services that represent the already mentioned area start pages and logical links. You can delete the latter, as these are duplicates from the other folders or non-relevant external services. Now, to set up correct permissions for the non-manageable external services in the GENERIC_OP_LINKS folder, you can identify the external services you need for your CRM business role and delete all other external services. However, as I said, there is a risk that too many external services will be deleted and cross-navigation or calling the saved searches will no longer work. It is better to move the GENERIC_OP_LINKS folder to a separate role.
The specific SAP_NEW authorization object imprints are provided via the SAP_BASIS component. Therefore, an SAP_NEW profile is always bound to a specific base release. Proceed as follows: With the transaction SU02, you remove all old, individual profiles from the SAP_NEW composite profile, including the profile that belongs to the start release of your upgrade. Now assign the reduced SAP_NEW permission profile to all users in the upgrade preparation system, ensuring that all users can work as usual. This step can be omitted if you are following another method to identify missing permissions. Now check all permissions in all remaining profiles within the SAP_NEW summary profile that have a higher release level than the SAP_BASIS upgrade start release. Map all required permissions to all productive roles in your permission concept. You can do this for each intermediate release individually. The next step is to adjust the permissions in your productively used roles in the PFCG transaction, and then remove the corresponding permissions from the SAP_NEW profile using the SU02 transaction. Repeat steps 3 through 4 until the SAP_NEW permission profile is empty. Work in a development system during the role adjustment phase and transport the adjustments made to your eligibility roles to your quality assurance system. After successful acceptance test, you transport them to the production system. Now you can remove the SAP_NEW profile from all users. You can then proceed with role follow-up as part of the release change in the SU25 transaction (see also Tip 43, "Customise Permissions After an Upgrade").
Existing permissions
When assigning a new user group to a user, only the creation permission in the new user group is required. Alternatively, you can enable the check for activity 50 (Move) of the S_USER_GRP authorization object. In the USR_CUST table, set CHECK_MOVE_4_CNG_GRP to YES.

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.
