  Release or Complete the Current Wave: If the item is assigned to a wave that is still in process, you may need to either complete or release that wave before assigning the item to a new wave.
  Modify Wave Assignment: If you need to change the assignment, consider removing the item from the current wave first, then reassign it to the desired wave.
  Consult with Warehouse Management: If you are unsure about the implications of changing wave assignments, consult with your warehouse management team to ensure that the changes align with operational procedures.
  Review Configuration: If this issue occurs frequently, review the configuration settings in EWM to ensure that they align with your business processes regarding wave management.
