  Saving the changes.
  
  
  
  Check Configuration: Ensure that the system configuration allows for the handling of serial numbers and handling units as intended. This may involve checking settings in the EWM configuration.
  
  
  User Authorization: Ensure that the user has the necessary authorizations to perform changes on handling units and serial numbers.
