In case of missing authorizations, SAP Basis also helps with an authorization trace in addition to the well-known SU53 for a more detailed analysis of authorization objects. The article "SAP Basis Basic or finding missing authorizations thanks to SU53 or ST01 Trace" describes this in more detail.
In these cases, the total permissions from the RFC_SYSID, RFC_CLIENT, and RFC_USER fields will not be applied. However, you will always see a system message. These constraints cannot be changed by the settings of the customising switch ADD_S_RFCACL in the table PRGN_CUST.
Extend permission checks for documents in FI
Since SAP NetWeaver 7.02, such a feature is available, which means that you can access the data from the system trace to maintain PFCG roles. In the following we show you how you can apply the permission values from the permission trace to your role. To do this, you must first record applications against their permission checks and then add them to your role menu.
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.
"Shortcut for SAP systems" is a tool that enables the assignment of authorizations even if the IdM system fails.
SAP Basis is the foundation of any SAP system. You can find a lot of useful information about it on this page: www.sap-corner.de.
However, the preferred and more comprehensive variant of a programmatic permission check is the use of the AUTHORITY_CHECK_TCODE function block.
A note box in which data of all kinds can be quickly filed and retrieved. This is what Scribble Papers promises. At first, the program looks very spartan. But once a small structure is in place, you realise the great flexibility of this little helper.
Due to the complexity of an SAP® authorization concept, it is necessary that all essential aspects are set down in a written documented authorization concept.
