  Cause:
  
  Missing Function Module: The function module that is referenced in the error message is not defined or does not exist in the system.
  Incorrect Service Configuration: The OData service may not be properly configured to point to the correct function module.
  Transport Issues: If the function module was recently transported from another system, it may not have been transported correctly or may be missing dependencies.
  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 or not included in the service definition.
  
  Solution:
  
  Check Function Module: Verify that the function module referenced in the error message exists in the system. You can do this by using transaction SE37 (Function Builder) to search for the function module.

  Debugging: If the function module exists and is correctly configured, you may need to debug the OData service to see where the call is failing. Use transaction /IWFND/DEBUG to enable debugging for OData services.
