Solution approaches for efficient authorizations
WHY ACCESS CONTROL
A user reports that he or she is receiving a permission error even though you have granted him or her the required permissions. This could be due to a faulty buffering of the permission data. Although a user has been assigned a role with the correct permission data, this user is presented with a permission error due to missing permissions. This may be surprising at first glance, but it can almost always be fixed by a short analysis.
Further changes can be found when using the proof of use. When you click on the button (proof of use), you will receive a new selection. You can check which permissions, SU24 suggestion values, or SU22 suggestion values the authorization object uses. The ABAP-Workbench selection, as in previous releases, provides you with the proof of use for implementing the authorization object in programmes, classes, and so on. You can use the SAP NEW Data button to mark whether this authorization object is relevant to an SAP New role of a particular release.
Organisational allocation
Structural authorizations work with SAP HCM Organizational Management. They primarily define who can be seen, but not what can be seen, based on evaluation paths in the org tree. Therefore, structural authorizations should only be used together with general authorizations. The determination works via a so-called authorization profile. In this profile, the evaluation paths are used to define how to search on the org tree. Function modules can also be stored, which can be used to determine objects from Organizational Management using any criteria. This makes the structural authorizations very flexible.
In order to get an overview of the organisations and their structure, we recommend that you call the Org-Copier (in read mode!) for the various organisational fields via the transactions EC01 to EC15. The customising in the SPRO transaction allows you to define the organisation fields and their respective assignment in the corporate structure area.
With "Shortcut for SAP systems" you can automate the assignment of roles after a go-live.
The focus should be on saving the current authorization concept, since rebuilding it takes more time than cleaning it up.
There are also different requirements within the system landscape, e.g. on production or development systems.
