Organisationally restrict table editing permissions
Use SAP Code Vulnerability Analyser
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.
The AL08 transaction displays all logged-in users and their application servers. In the Server Name column, you can see which application server the user is logged on to, and which has the permission issue. Switch to this application server by calling the SM51 transaction and double-clicking the application server you are looking for. On the application server that is now active, run the permission trace as usual and review the evaluation.
Implementing the authorization concept in the FIORI interface
You must enable a role that you have created as a Design-Time object in the Design Time Repository before it can be associated with a user. To do this, use Project Explorer to select the role you want to enable and select Team > Activate from the shortcut menu. This will create a runtime object of this selected SAP HANA role. This object is also understood as a catalogue object and is incorporated in the Roles branch in the corresponding SAP HANA system.
In general, you should note that not all relevant change documents of a system are present in the user and permission management. As a rule, authorisation administration takes place in the development system; Therefore, the relevant proof of amendment of the authorisation management is produced in the development systems. By contrast, you will find the relevant user administration change documents in the production systems; Therefore, you should note that when importing roles and profiles in the production systems, no change documents are written. Only transport logs are generated that indicate that changes have been made to the objects. For this reason, the supporting documents of the development systems' authorisation management are relevant for revision and should be secured accordingly.
Authorizations can also be assigned via "Shortcut for SAP systems".
When called, the application started via a transaction checks whether the authorization exists and whether the user is allowed to perform the selected operation.
At www.sap-corner.de you will also find a lot of useful information on the subject of SAP authorizations.
It should therefore be checked whether all changes since the last audit have been documented in the written authorization concept.
