Mitigating GRC risks for SAP systems
Query Data from Active Directory
Armed with this information, it goes to the conceptual work. Describe which employee groups, which organisational units use which applications and define the scope of use. In the description, indicate for which organisational access (organisational level, but also cost centres, organisational units, etc.) the organisational unit per application should be entitled; So what you're doing is mapping out the organisation. It is also important to note which mandatory functional separation must be taken into account. This gives you a fairly detailed description, which in principle already indicates business roles (in relation to the system).
It should be noted, however, that the system writes all authorization errors of the user into the memory area of SU53. I.e. if there is a so-called double hit, i.e. several authorization errors occur, only the last error is always in this area. I prefer to have the user run the transaction until the error message "No authorization...", then use the menu to display the error, and send me a screen shot of the first page of output. This way I avoid that the user creates another authorization error when calling transaction SU53, which covers the original one. As a user administrator or role administrator, you can also call SU53 yourself and display the error entry of another user via the menu. However, this does not always work.

Any deviation from the defined process must be fully documented and justified. This is because it is precisely deviations from the standard case that are of great interest to an auditor, as the auditor must determine whether a deviation could have an impact on the correctness of the data.
In general, we recommend you to use strong encryption mechanisms and to switch most users to an SSO login. You should then delete the hash values of the user passwords as described above. For release-dependent information on SNC client encryption, see SAP Note 1643878.
However, if your Identity Management system is currently not available or the approval path is interrupted, you can still assign urgently needed authorizations with "Shortcut for SAP systems".
The website www.sap-corner.de offers a lot of useful information about SAP authorizations.
In the validation process, copy the RGGBR000 programme into your Customer Name Room, replacing the last three characters with the number of the client in which the validation will be performed.
You can prevent this behaviour by setting the login/no_automatic_user_sapstar profile parameter to 1.
