  Review Characteristics: Go through the characteristics defined for the material and ensure that each one is unique and serves a distinct purpose. Remove or modify any duplicates.
  Check Class Assignment: Ensure that the class assigned to the material does not have conflicting characteristics. You may need to adjust the class definition.
  Modify Configuration Profile: If you are using a configuration profile, check the settings to ensure that they are correctly set up and do not lead to conflicts.
  Test Configuration: After making changes, test the configuration again to see if the error persists. You can do this by trying to create or change the configuration of the material.
  Consult Documentation: Refer to SAP documentation or help resources for more detailed guidance on setting up characteristics and classes in Variant Configuration.
