When a delivery trip is released, a check is made whether cost lines have been created for the trip. Based on the setting in Transport and Deliveries Setup, a warning or error appears when no cost lines are found.
Add transport costs to a delivery trip the same way as to a transport order: Add transport order cost lines.
When costs must be specified per delivery trip stop, create the cost lines from the transport order. When costs are added to the delivery trip, the assumption is that these costs apply to the entire trip.
