Negative freight costs

You can specify negative freight costs for loads, shipments, and shipment lines. For example, if a customer is overcharged for a shipment, you can compensate the customer by charging a negative freight cost amount for the next shipment.

Redistribute manually changed freight costs

If the freight costs are changed for a load, the changed freight costs, including any negative freight costs, are proportionally distributed among the shipments and shipment lines of the load. If the freight costs are changed for a shipment line, the costs are added up for the shipment and the load.

The formula to redistribute manually changed freight costs:

Current value of object / total value of same level objects * cost increase of 
higher level object

In the formula, only absolute numbers are used. Object refers to load, shipment, or shipment line.

If the freight costs of a load are changed to zero, the freight costs of the shipments and shipment lines of the load also become zero.
