AFWCH_FL039 - Details

• The SAP error message AFWCH_FL039 indicates a compatibility issue between two characteristic values in the context of variant configuration or classification. This error typically arises when there is an attempt to assign a value to a characteristic that is not compatible with the value of another characteristic.
  
  Cause:
  
  Incompatible Characteristics: The error occurs when the value of characteristic &3 (which is being assigned) is not compatible with the value of characteristic &1 (which is already assigned). This can happen due to predefined dependencies or constraints in the configuration model.
  Dependency Rules: There may be dependency rules defined in the configuration that restrict certain combinations of characteristic values. If the combination of values does not meet these rules, the error will be triggered.
  Incorrect Configuration: The configuration of the product may not be set up correctly, leading to incompatible values being selected.
  
  
  Solution:
  
  Check Compatibility: Review the compatibility of the characteristic values. Ensure that the value of
