  Check Material Master Data:
  
  Go to the material master record for the item in question and verify the base unit of measure and the alternative units of measure.
  Ensure that the UoM assigned to the transaction matches the base UoM or is correctly defined in the material master.
  
  
  
  Adjust Transaction Data:
  
  If the error occurs during a transaction (like sales order or purchase order), check the UoM used in that transaction and change it to match the base UoM or a valid alternative UoM.
  
  
  
  Review Configuration:
  
  If the issue persists, review the configuration settings in the SAP system related to units of measure. This may involve checking the settings in the customizing transaction (SPRO) for material management and ensuring that the UoM conversion factors are correctly defined.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for specific guidance on handling UoM issues, as there may be additional steps or considerations based on your specific SAP version or configuration.
