  The SAP error message SCPRFC031, which states "Set LANG; & &. Before RADNTLANG," typically occurs in the context of Remote Function Calls (RFC) when there is an issue with the language settings in the SAP system. This error indicates that the language parameter is not set correctly before executing a function module or a remote call.
  Cause:
  
  Language Parameter Not Set: The error usually arises when the language parameter (LANG) is not specified or is set incorrectly in the RFC call.
  Configuration Issues: There may be issues with the configuration of the RFC destination or the settings in the SAP system that prevent the language from being recognized.
  User Profile Settings: The user profile may not have a default language set, leading to this error when trying to execute functions that require a language specification.
  
  Solution:
  
  
  Set the Language Parameter: Ensure that the language parameter is explicitly set in the RFC call. This can typically be done by modifying the code that makes the RFC call to include the language parameter.
  
  Example: If you are using ABAP, you can set the language like this:
  CALL FUNCTION 'RFC_FUNCTION_NAME'
    DESTINATION 'RFC_DESTINATION'
    EXPORTING
      LANGU = 'EN'  " Set the desired language code
      ...
  
  
  
  
  Check RFC Destination Configuration: Verify the configuration of the RFC destination in transaction SM59. Ensure that the language settings are correctly configured.
  
  
  User Profile Language Setting: Check the user profile settings in transaction SU01 for the user executing the RFC call. Make sure that a default language is set.
  
  
  Review Function Module Documentation: If you are calling a specific function module, review its documentation to see if there are any specific requirements regarding language settings.
  
  
  Debugging: If the issue persists, consider debugging the RFC call to see where the language parameter is being set or if it is being overridden somewhere in the code.
