  Solution:
  
  Verify Serial Numbers: Check the serial numbers assigned to the Handling Unit. Ensure that the number of serial numbers matches the quantity of items in the HU.
  Adjust Serial Number Assignment: If there are missing serial numbers, you may need to assign the correct number of serial numbers to the Handling Unit. This can typically be done through the EWM interface.

  Check Configuration: Review the configuration settings in SAP EWM related to Handling Units and serial number management to ensure they align with your business processes.
  Consult Documentation: Refer to SAP documentation or help resources for specific steps on handling serial numbers and HUs in your version of SAP EWM.
