  Authorization Issues: The user credentials used for the RFC connection may not have the necessary authorizations.
  System Configuration: The target system may not be properly configured to accept RFC connections.
  Transport Directory Issues: Problems with the transport directory or transport routes can also lead to this error.
  
  Solutions:
  
  
  Check RFC Destination:
  
  Go to transaction SM59 and check the configuration of the RFC destination that is causing the issue.
  Test the connection using the "Test Connection" button to ensure it is working correctly.
  
  
  
  Verify Network Connectivity:
  
  Ensure that there are no network issues preventing communication between the systems.
