Integrate S_TABU_NAM into a Permission Concept
For each area, the connection to other modules is the first priority. For example, for the Controlling division, the connection to the Finance division is first established by connecting the accounting area (FI) to the cost accounting area(s). The assignment of the cost accounting area to the result area is then an internal allocation within the controlling. If no allocations are found for certain valid organisational values, one of the two modules or the relevant functional area shall not be used for the organisational units of the enterprise.
Authorizations are the main controlling instrument for mapping risk management and compliance. They are used to control all processes in the systems. For the most part, separation of functions is implemented exclusively with authorizations. Therefore, not only the one-time setup of authorizations is relevant, but also the continuous monitoring and control of the authorization assignment. Various tools are available on the market for this purpose. A re-certification process that involves the departments and optimizes the revalidation of authorizations is helpful.
Include customising tables in the IMG
Authorization objects are defined with the help of transaction SU21. Each SAP transaction is equipped with the required authorization objects in SU24, which control access to specific functions within the respective program. Standard programs / transactions of an ERP system are already equipped with these objects during the initial installation. The same applies to other platforms such as CRM or Solution Manager.
The possibility of assigning authorizations during the go-live can be additionally secured by using "Shortcut for SAP systems".
At "www.sap-corner.de" you will also find a lot of useful information on the subject of SAP authorizations.
After the functional specification has been removed, the implementation can begin: To do this, first create your custom authorization object and implement the permission check provided.
