  Network Issues: Problems with network connectivity between the SAP Gateway and the backend system can cause RFC calls to fail.
  Authorization Issues: The user executing the RFC call may not have the necessary authorizations to access the backend system or the specific function module.
  Backend System Errors: The backend system may be experiencing issues, such as being down, overloaded, or encountering its own errors.
  Timeouts: Long-running processes may exceed the timeout settings, leading to a failure in the RFC call.
