  SAP Error Message:
  WGDS_ENH129: Material category can be changed only after saving the converted variants
  
  
  Cause:
  This error occurs in the Variant Configuration process, specifically when working with configurable materials in SAP. The message indicates that you are trying to change the Material Category of a configurable material before saving the converted characteristic variants.
  
  In SAP Variant Configuration, when you convert characteristics or variants, the system requires that these converted variants be saved first.
  The material category (e.g., configurable material category like KMAT) is linked to the variant characteristics.
  Changing the material category before saving the converted variants can lead to inconsistencies or data loss, so SAP prevents this action.
  
  
  When does it typically occur?
  
  During the creation or modification of configurable materials (material category KMAT).
  When you convert characteristics or variants in the material master or classification.
  When you try to change the material category before completing the variant conversion
