  The SAP error message /SCWM/SHP_RCV381 TU &1 is already assigned to vehicle &2 typically occurs in the SAP Extended Warehouse Management (EWM) module when there is an attempt to assign a Transportation Unit (TU) to a vehicle that is already assigned to another vehicle. This can happen during the process of transportation planning or execution.
  Cause:
  
  Duplicate Assignment: The Transportation Unit (TU) is already linked to a different vehicle, and the system does not allow multiple assignments for the same TU.
  System Configuration: There may be specific configurations or settings in the system that restrict the assignment of TUs to vehicles.
  User Error: A user may be trying to assign the same TU to multiple vehicles without realizing it.
  
  Solution:
  
  Check Current Assignments: Verify the current assignments of the Transportation Unit. You can do this by checking the TU in the system to see which vehicle it is currently assigned to.
  Reassign the TU: If you need to assign the TU to a different vehicle, you may need to first unassign it from the current vehicle. This can typically be done through the EWM interface.
  Review Processes: Ensure that the processes for assigning TUs to vehicles are being followed correctly. This may involve reviewing user training or system documentation.
  Consult Logs: Check system logs for any additional error messages or warnings that may provide more context about the issue.
  System Configuration: If the issue persists, consult with your SAP Basis or EWM configuration team to review the settings related to Transportation Unit assignments.
