  Review Characteristic Settings: Check the settings of the reference characteristic in the InfoObject maintenance. Ensure that it is correctly defined and that there are no conflicting settings that might lead to this error.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for more detailed information on how to work with reference characteristics and the implications of excluding values.
  
  
  Testing: After making changes, test the query or data model again to ensure that the error is resolved.
