Detect critical base permissions that should not be in application roles
Excursus Special feature for authorizations for FIORI Apps under S/4HANA
In the only method of the BAdIs, CHANGE_ITEMS, programme the necessary checks, such as on specific data constellations or permissions. These can refer to all fields in the FAGLPOSX structure. You do this by specifying that all lines for which the test was not successful will be deleted during the execution of the method. This implementation of the BAdIs complements the Business Transaction Event 1650 described in the second example. You can also use the FB03 transaction to display receipts in the same way that you implement the FB03 filter. In this case, implement the required checks in the BAdI FI_AUTHORITY_ITEM.
Now check the SY-SUBRC system variable. If the value is 0, the Permissions Check succeeded. If the value is 4, the test did not pass. At a value of 8, there is an inconsistency in the definition of the authorization object and the verification in the code - this should not happen! If the value is 12, the permission is not part of your permission buffer.
Optimization of SAP licenses by analyzing the activities of your SAP users
The panel menus also simplify the maintenance of permissions to the audit structures. You can select the audit structures or area menus you use in role editing and import them into the roles as menus. If you want to set up a constraint on AIS users to specific audit structures or protect individual audits from access, you can use the S_SAIS authorization object. This object controls access to the audit structures or the audit numbers of individual audits.
If business partners are deposited to the user IDs, the standard evaluation paths lead to a dead end. Adjust it so that the indirect role mapping works anyway. In SAP CRM, you can set up an organisation management, as in SAP HCM. You can maintain organisational units and posts and assign business partners with their user IDs. In SAP CRM, however, there is the specificity that user IDs are not directly assigned to a job, but are usually indirectly assigned by the associated business partner. All persons and organisations involved in business processes are represented as business partners in SAP CRM.
For the assignment of existing roles, regular authorization workflows require a certain minimum of turnaround time, and not every approver is available at every go-live. With "Shortcut for SAP systems" you have options to assign urgently needed authorizations anyway and to additionally secure your go-live.
In addition to these requirements, other settings can ensure that the transaction can be performed without verification: Verification of eligibility objects is disabled by check marks (in transaction SU24).

Therefore, not only the one-time setup of authorizations is relevant, but also the continuous monitoring and control of the authorization assignment.
