  Check Current Assignments: Verify the current assignments of the vehicle in question. You can do this by checking the Transportation Unit details in the EWM system to see which vehicle is currently assigned.
  Reassign Vehicle: If you need to assign a different vehicle, first unassign the existing vehicle from the TU. This can usually be done through the EWM interface by selecting the TU and choosing the option to change or remove the vehicle assignment.
  Use a Different Vehicle: If the vehicle is indeed in use, consider using a different vehicle that is not currently assigned to any TU.
  Review Configuration: If this issue persists, review the configuration settings in the EWM system to ensure that there are no restrictions or settings that could be causing this error.
  Consult Documentation: Refer to SAP documentation or help resources for more detailed steps on managing vehicle assignments in EWM.
