Switchable authorization checks for RFC in SEM-BCS, SAP security note 2100926

SAP Note 2100926

SAP security note 2100926, "Switchable Authorization Checks for RFC in SEM-BCS". Below are the symptom and SAP recommended solution.

Description

Symptom

Remote calls to RFC function modules are currently protected by the S_RFC authorization object. However, S_RFC alone may not suffice to ensure secure execution for certain RFC function modules within SEM-BCS. This gap necessitates the activation of additional authorization checks.

Solution

The SAP Note implements new switchable authorization checks that are initially inactive to maintain compatibility with existing processes. These checks can be activated using transaction SACF. Detailed steps for activation are provided in the manual correction instructions included with the note.
