What are SAP authorizations?
Authorization check
Authorization tools are only as good as the person using them. Until now, no tool has made it possible to create ready-made authorization concepts with just a single click.
Some queries are also a bit complicated with the SUIM transaction. With SAP Query, you can quickly assemble queries that enable individual and more complex data evaluations. Do you want to know quickly which valid users currently have a modified access to a particular table, or what roles are users granted permission for a particular transaction? The SAP standard tool, the user information system, is an excellent solution for this type of data retrieval. However, at the latest during the next review, targeted queries with data combinations - and thus several SUIM query sequences - must be delivered within a short time. SAP queries can facilitate this task. An SAP Query is essentially a clear way to scan tables for specific data away from the SE16 transaction. There is the possibility to link multiple tables (join), which makes multiple SE16 queries just one SAP query. For example, if you want to know what roles users are entitled to perform the SCC4 transaction, you can use the SUIM transaction to query to determine which users can perform the transaction and view the roles that enable it in another query, but there is no result that shows both.
Maintain permission values using trace evaluations
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).
With the transaction SUIM you can search under roles, roles with different search criteria. The variant "Roles by complex selection criteria" covers all possible selection criteria. However, you can also search only for a specific selection criterion (e.g. only for transactions, only for authorization objects...).
"Shortcut for SAP systems" is a tool that enables the assignment of authorizations even if the IdM system fails.
The future assignment of such transactions in the SAP role concept should then be critically questioned.
To minimize the risk of a system failure or the creation of a security vulnerability, administrative rights should only be granted to employees in the basic administration.
