The SAP authorization concept
Criticality
SAP authorizations control the access options of users in an SAP system, for example to personal data. Managing this access securely is essential for every company. This makes authorization concepts, authorization tools and automated protection of the SAP system all the more important.
You can now assign transactions to these roles. Experience has shown that roles should remain application-specific and that a distinction between book or investing, changing and reading roles is also useful. There will be regular transactions used in multiple roles. You should not overestimate the often demanded freedom of redundancy. However, for critical transactions or transactions that are involved in a functional separation conflict, it is recommended that they be kept in a separate role. In general, roles should not contain too many transactions; Smaller roles are easier to maintain and easier to derive. Also, assigning them does not quickly lead to the problem that users have too many permissions. If you keep the necessary functional separations in place, you have already prepared them as a takeaway.
User Information System (SUIM)
On the one hand, sensitive company data must not fall into the wrong hands, but on the other hand, they also form an important basis for decisions and strategic company directions. Avoid a scenario of accidentally accessible data or incomplete and thus unusable reports by implementing your SAP BW authorizations properly.
After creating a authorization object, you should do the following: Make the permission check implementation at a convenient location in your code. Maintain the proposed values for the application in the transaction SU24. Re-load the role in the PFCG transaction if the application has already been rolled. If it is a new application, adjust the roles by including the new application in the Role menu, and then maintaining the permissions of the authorization objects loaded into the role by the suggestion values.
"Shortcut for SAP systems" is a tool that enables the assignment of authorizations even if the IdM system fails.
In transaction RZ11 you can easily and quickly check if the parameter is already set.
