StarShip writes back to the Sage 300 Shipment when you process it in StarShip. The freight charge writes back to a separate line item under the Miscellaneous Charge Code you set up. The forward-slashes in the Description field indicate that this information has been written by StarShip. The actual freight charge is shown in the Ext. Price field.
