W+223 - Details

• The SAP error message W+223 indicates that you are trying to change the unit of measure for a specific material that is not allowed at that level. This error typically occurs when you attempt to modify the unit of measure for a specific material (or variant) instead of the generic material.
  
  Cause:
  
  Generic vs. Specific Material: In SAP, materials can be defined as generic materials (which can have multiple variants) and specific materials (which are individual instances of a generic material).
