PFCG Authorization maintenance for object S_RFCACL, SAP security note 1416085

Description

Every RFC function call requires a logon to the called system. As long as the RFC connection was defined as trust (transaction SM59, “Logon & Security” tab page), the target system checks in addition to the S_RFC for the requested function an authorization for the object S_RCFACL. For which user these checks are carried out depends on the definition in the RFC connection.
Entries in the fields RFC_SYSID, RFC_CLIENT or RFC_USER to S_RFCACL define from which systems, clients, or for which user IDs logons to the target system are accepted. If you enter the full authorization (*) in one or more of these three fields, you allow the logon from any system, client, or any user, and as a result, you may produce significant security risks.
