Use the Route, References and Containers task to record important information about truckload (TL) or less than truckload (LTL) shipments; this task is not typically used for small parcel shipments, particularly if they are domestic shipments. You may want to record information for inclusion in shipment documentation; for example, customs and freight payment information. Typically, you enter this data before manifesting the shipment, so that the documentation accompanies the shipment. Also, if you use a separate ERP system to track your shipments, the information you add in this task can be sent to the ERP system.
