This field contains the direct unit cost of the item on the line.
The program automatically retrieves the cost from the Last Direct Cost field in the Item table. If the Item Vendor table contains a cost for this vendor, the program will enter that price instead.
If you change the direct unit cost, the program updates the contents of the Line Amount and Line Discount Amount fields. The contents of the Inv. Discount Amount field will be deleted if the direct unit cost is changed. This means that the invoice discount amount will have to be recalculated.
