  Causes:
  
  Function Module Not Created: The function module specified in the error message has not been created in the SAP system.
  Incorrect Function Module Name: There may be a typo or incorrect name in the function module being called.
  Transport Issues: The function module may exist in the development environment but has not been transported to the production environment.
  Authorization Issues: The user may not have the necessary authorizations to access the function module.
  Namespace Issues: The function module might be in a different namespace that is not accessible from the calling program.

  Check Function Module Existence:
  
  Use transaction SE37 to check if the function module exists. Enter the name of the function module and see if it is available.
  
  
  
  Verify Function Module Name:
  
  Double-check the spelling and case of the function module name in the code that is calling it.
