This error typically occurs when you are trying to create or process a service entry sheet for a service that has been ordered with a different unit of measure than what is being used in the SES.

  Unit of Measure Mismatch: The unit of measure used in the SES does not match the unit of measure defined in the PO for the same service item.
  Incorrect Data Entry: The user may have mistakenly entered the wrong unit of measure while creating the SES.
  Configuration Issues: There may be issues with how the units of measure are configured in the system, leading to discrepancies.
  
  Solution:
  
  
  Check the Purchase Order: Review the Purchase Order (PO) to confirm the unit of measure defined for the service item. You can do this by navigating to the PO in the SAP system and checking the item details.
  
  
  Verify the Service Entry Sheet: Check the Service Entry Sheet (SES) to see what unit of measure has been entered. Ensure that it matches the unit of measure in the PO.

  Recreate the SES: If the SES has already been saved and cannot be edited, you may need to delete the SES and create a new one with the correct unit of measure.
  
  
  Consult with Configuration Team: If the issue persists or if you suspect a configuration problem, consult with your SAP configuration team to ensure that the units of measure are set up correctly in the system.
  
  
  Related Information:
