  The SAP error message DMCLG309, which states "RFC settings have been saved," typically indicates that there has been a change or update to the Remote Function Call (RFC) settings in the SAP system. This message is not necessarily an error but rather an informational message indicating that the settings have been successfully saved.
  Cause:
  
  Configuration Changes: The message usually appears after making changes to the RFC destination settings in transaction codes like SM59 (RFC Destinations).

  User Actions: Users may have modified settings related to communication between different SAP systems or between SAP and non-SAP systems.

  Verify Settings: After receiving this message, it is essential to verify that the RFC settings are correct. Check the destination settings in SM59 to ensure that the connection parameters (like target host, system number, client, user, password, etc.) are accurate.
  Test Connection: Use the "Test Connection" feature in SM59 to ensure that the RFC destination is working correctly. This will help confirm that the settings are valid and that the connection can be established.
  Check Logs: If you encounter issues after saving the settings, check the system logs (transaction SM21) and the RFC trace (transaction SM59 -> select the destination -> "Display" -> "Trace") for any errors or warnings that may provide more context.
  Consult Documentation: If you are unsure about the settings, refer to SAP documentation or consult with your SAP Basis team for guidance on the correct configuration.
