Early-payment discounts in payment proposals

A payment proposal takes a discount only from the supplier's own payment term, and only when the payment date is inside that term's discount window.

• Set the supplier's payment term on the supplier's business-unit terms or financial terms. A supplier with no term set gets no discount.
• When the payment batch is transmitted, the discount is posted to the purchase discounts account (or the default expense account if your chart has none) and the invoice is closed as paid.
• The payment register shows the discount as its own settlement line, with the method 'discount'.
