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.
No external services can be added manually in transaction SU24. To do this, you must turn on a permission trace that takes over. You can enable the permission trace using the auth/authorisation_trace dynamic profile parameter. You can enable this parameter by using the transaction RZ11 (Profile Parameter Maintenance) by entering the value Y as a new value and selecting the Switch to All Servers setting.

However, the greatest advantage is the consistent use of reference users for performance. The use of reference users reduces the number of entries per user in the user buffer, i.e. in the USRBF2 table. This is because the entries in the user buffer only have to be stored once for the reference user and not more times for the inheriting users. This reduction in the table contents of the USRBF2 table will improve performance when performing eligibility tests.
If you set the profile parameter dynamically, no users are logged out of the application server. You can prepare maintenance work in good time. The value 2 in the profile parameter does not prevent the login with the emergency user SAP*, if this is not set as user master record and the profile parameter login/no_automatic_user_sapstar is set to 0. You can also change the value of the parameter again at the operating system level. For details on the SAP user, see Tip 91, "Handling the default users and their initial passwords".
"Shortcut for SAP systems" is a tool that enables the assignment of authorizations even if the IdM system fails.

The smallest possible value is three days, without taking the current day into account in the calculation.
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.
