This field indicates how much of the line should be invoiced.
This field is used only when you post orders.
Each time the Quantity field is updated and you post an order, the program will automatically suggest invoicing the quantity that has not yet been invoiced. It calculates this quantity as the difference between the Quantity and Quantity Invoiced fields.
Note that it is never possible to invoice more than you have received.
When you post, you will not create an invoice unless the order contains at least one line for which the Qty. to Invoice is not zero.
The program automatically updates this field when you invoice or change the Quantity field.
