Create permissions for customising
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.
As a role developer, you can now select the specific application in the PFCG transaction from the list of web dynpro applications published by the software developers on the Menu tab and enter it in the Role menu. To generate the role profile, switch to the Permissions tab. There you can check the concrete value expressions of the S_START permission fields and, if necessary, the additional relevant authorization objects for this Web application and supplement them if necessary. Finally, you must generate the role profile as usual.
Every large company has to face and implement the growing legal requirements. If the use of an authorization concept is to be fully successful on this scale, the use of an authorization tool is unavoidable. For medium-sized companies, the use of an authorization tool is usually also worthwhile. However, decisions should be made on a case-by-case basis.
SAP Note 1707841 ships an extension to the system trace in the STAUTHTRACE transaction, which enables the permission trace to be used on all or on specific application servers. To select the application servers on which to start the trace, click the System Trace button. Now select the application servers in the list on which you want to run the system trace and start the trace with a click on Trace. In the evaluation of the Permission trace, an additional column named Server Name appears, showing you the name of the application server on which the respective permission checks were logged.
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".
When you click Run, all users and the triggers are output to you.
