When making a remote function call (RFC) using a destination type 3 (ABAP Connection) with Trusted Relationship issues may occur. The following messages are raised on the client end: 

  • "No authorization to log on as a trusted system (Trusted RC = #)." 
  • "No authorization to log on as a trusted system (L-RC=# T-RC=#)"

This article aims to explain the meaning of these return codes and what should be done to have a successful RFC with Trusted Relationship.
