Applying addon charges to a purchase order
You can apply purchase order addons, such as freight, to a new or existing purchase order.
Note:  Purchase order addons must be
            set up in SA Table Code Value Setup, and then can
            be designated for a specific vendor in Vendor
            Setup. Any addons designated for a vendor are automatically applied to the
            purchase order. The exception would be if the addon is a capitalized addon, and you have
            not selected Include Addons in SA-Administrator Options-Products-Costs. You can apply up
            to four addons. Capitalized addons are applied first, and expensed addons second.
