Integrate S_TABU_NAM into a Permission Concept
Maintain authorization objects more easily
We are often asked how permissions are properly assigned to schedule background jobs and manage those jobs. Just follow the guidelines below. Whenever you want programmes to run periodically at specific times without user interaction, or when their runtime should not interfere with normal dialogue operations, schedule them as batch jobs in the background. The scheduling and editing of batch jobs is regulated by permissions, which are often not clear about their use. We therefore explain to you what permissions are necessary for and which authorization objects are important.
In addition to defining permissions for external RFC access through the S_RFC authorization object, it is possible to prevent external calls to function blocks. From SAP Net-Weaver AS ABAP 7.40 there is the additional SAP Unified Connectivity (UCON) layer. It controls external access to RFC function blocks independently of users or roles and can be configured to suit your needs. All function modules that are to be executable via RFC are entered into the UCON Communication Assembly. If a function block is not stored there, the call will be blocked. UCON has been designed to minimise impact on RFC call performance. The necessary function blocks are identified in the UCON Phase Tool (transaction UCONPHTL), which constantly monitors all external RFC calls and supports an introduction of the UCON Communication Assembly. This allows calls to new function blocks (such as custom developments, support package changes) to be analysed and, if necessary, released for external access. In addition, UCON offers the possibility to review the configuration in an evaluation phase. There are approximately 40,000 RFC-enabled function blocks in an ERP system; Usually no more than a few hundred of them are used. With the use of UCON you therefore increase the security of your system.
Detect critical base permissions that should not be in application roles
Only adding an authorization object via SU24 does not automatically result in a check within the transaction. The developer has to include an authorization check exactly for this object in the program code.
Set a specific acronym or character to indicate whether your role has critical accesses so that separate assignment or approval rules can be observed for such roles. Define here what"critical"means for your project. Do you only want to identify permissions that are critical to the operation of the SAP system, or business-critical processes? Also define the consistency that has a critical role to play in the assignment to the user.
If you get into the situation that authorizations are required that were not considered in the role concept, "Shortcut for SAP systems" allows you to assign the complete authorization for the respective authorization object.
Enter"S_TCODE"as object and"SCC4"as field value (we only have one field for this object).
