  Set Default Language: If applicable, set a default language in the user profile settings. This can often be done in the user settings in the SAP GUI.
  Review Configuration: Check the configuration of the RFC destination in transaction SM59 to ensure that all required parameters, including language, are correctly set.
  Debugging: If you have access to the code making the RFC call, add debugging or logging to verify that the language parameter is being populated correctly before the call is made.
  SAP Notes: Check for any relevant SAP Notes or updates that might address this issue, as there may be patches or updates that resolve underlying bugs.
