Transfer vehicles which will be used to conduct shipment operations, vehicle capacities, routes they will follow are recorded and monitored in Shipment System. 
Transfer vehicles, their capacity and routes are saved in definition cards. The relevant vehicles and routes they will take are specified in shipment slips. Both planned and unplanned return transactions are also tracked and reported with shipment slips at the same time. You can ensure automation by establishing shipment connection with slips and invoices which are recorded in Sales Management module.
