Freight discounts/uplifts only apply to costs specified in the system value, or to the default cost types—freight and fuel—when no cost types are specified. The type of a cost is determined by a setting in option CH, as displayed in CH Option and Charge/revenues Update.

The Charge/revenues section enables you to specify that the cost is of type Freight or Fuel Surcharge. If the service type is set to None, a cost is of type Freight. Minimum charges only apply to Freight cost types. On the Shipment Charges record in PRECISION—the XMSOVR0 table— the customer charge field is SOEVAL and the carrier charge field is SOSEVAL.
