Assignment of critical authorizations and handling of critical users
Dialogue user
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.
In the SU53 you get the entry of the user that is stored there, and this may be old. So it is better to let the user himself display the authorization error via the menu. Maybe you create a small docu for all your users how to display the error and where to send it, so a "Cooking Recipe: How To...". In the SU53 error excerpt, the first thing that is displayed is the authorization that the user is missing. So this object has to be analyzed. In the further part of the error message, the permissions assigned to the user are displayed. This information can be used to classify the user with his role set, where he belongs etc. Finally, in our case 1, we now have the missing authorization and must now clarify whether the user should receive this authorization or not. In addition the specialist department must be contacted, which has to decide whether the user receives the permission! It can happen that the problem reported by the user is not an authorization problem at all. Then the last authorization error is displayed in the SU53 area, which is not the cause of the error at all. Therefore, it is always good to have a screen image of the actual error message sent to you as well. It is not uncommon for developers to issue an authorization error of the type "No authorization for..." from their programs, but they have not checked this with a standard authorization check at all, so that the error is not an actual authorization error.

To establish an efficient and consistent structure in the area of SAP authorization management, function-related role and authorization assignments are the be-all and end-all. In addition, the existing authorization concept must be constantly analyzed for changes and security-relevant errors through proactive monitoring. This prevents negative and highly security-critical effects on your entire system landscape. To make this task easier for you, Xiting provides you with a comprehensive analysis tool, the Xiting Role Profiler. In addition, you can perform a basic analysis in advance, which will also be the main focus of this blog. The goal is to show you SAP standard methods with which you can already independently optimize your authorization and role administration.
Make sure that reference users are assigned minimal permissions to avoid overreaching dialogue user permissions. There should be no reference users with permissions that are similar to the SAP_ALL profile.
The possibility of assigning authorizations during the go-live can be additionally secured by using "Shortcut for SAP systems".
There will always be inactive users in your SAP system.
It can be used to assess and classify the risks arising from SAP authorizations.
