  Missing Conversion Factor: The primary cause of this error is that the conversion factor between the base unit of measure and the shadow item’s unit of measure is not defined in the material master data.
  Incorrect Configuration: There may be an issue with the configuration of the material master or the related settings in the SAP system.
  Data Inconsistency: There could be inconsistencies in the data, such as missing entries or incorrect settings in the unit of measure tables.
  
  Solution:
  
  
  Check Material Master Data:
  
  Go to the material master record (transaction code MM03).
  Check the "Units of Measure" view to ensure that all necessary units of measure are defined and that conversion factors are correctly set up.
