  The TU is associated with a delivery that has issues (e.g., not fully delivered, delivery blocked).
  
  
  
  Warehouse Management Settings: There may be specific settings or configurations in the warehouse management that prevent unloading, such as:
  
  Unloading zones not being properly configured.
