  Cause:
  
  Invalid Unit of Measure: The unit of measure specified for the GTIN does not exist in the system or is not correctly defined.
  Configuration Issues: There may be configuration issues in the material master or the GTIN settings that lead to the system not recognizing the UoM.

  Maintain Master Data:
  
  If the UoM or GTIN is missing, you may need to create or update the relevant master data using transaction codes like MM01 (Create Material) or MM02 (Change Material).
