After a BOL is created, there may be some details, such as the date,
items and accesorials that need to be changed. These could affect the rate, so to change them, use the Recalculate link. You'll be taken back to the rating screen where you can add edit the accessorials, items and ship date. After saving your changes you'll be returned to the Shipment details screen and the new rate will be reflected in the Rate Details section.
