RFC_NO_AUTHORITY

RFC call fails with RFC_NO_AUTHORITY

RFC-enabled function call fails because the technical/user account lacks authorization for the called RFC function group/function.

Likely root causes

  1. S_RFC authorization is missing for the called function group/function.
  2. Destination uses a user different from the one tested interactively.
  3. Recent role changes are not active in the remote session.

What to inspect

  1. SM59 destination user and connection test.
  2. SU53/STAUTHTRACE in the target system under the RFC user.
  3. S_RFC object values and function group/function being called.
  4. SM20/security log when relevant.

Resolution path

  1. Grant the minimum S_RFC authorization required by the interface.
  2. Confirm the destination uses the intended technical user.
  3. Refresh/retest the remote session after role changes.
  4. Avoid broad wildcard RFC authorization unless explicitly justified and governed.
