Discount

The total cash discount amount available for early payment on the document.  If entered, this amount will be validated against the sum of discount amounts on the detail lines.  If not entered, and the credit terms specify a discount percentage, then this amount will be calculated as the total from the detail line discount amounts.  The discount amount must be less than the gross amount. 

Cash discount amount that will be subtracted from the gross amount to get the net amount due.  The discount is only available if the open item is paid before the discount date.  The discount amount is calculated if this field is left blank and the payment terms allow a discount.  In a VAT environment where the VAT processing option is to recalculate, the VAT subject to discount should be included in this total. 

The system calculates the total discount entered or calculated on the detail screen.  This total is displayed on the Detail line.  The difference between the header and detail totals is shown on the Difference line.  The difference represents missing distribution lines or incorrect open item totals.  You cannot end this transaction until the difference is zero.
