When all the items have been entered on the sales order lines, you can calculate the invoice discount for the entire sales document by choosing Actions and then choosing Calculate Invoice Discount.
If the Calc. Inv. Discount field is selected in the Sales and Receivables Setup window, then the invoice discount is calculated automatically. For more information about when the automatic calculation occurs, see Calc. Inv. Discount.
The discount is apportioned over all the lines in the sales document for items where the Allow Invoice Disc. field on the sales order line contains Yes. This is the default setting for items.
The invoice discount terms are defined in the Cust. Invoice Disc. table to calculate the invoice discount. The currency code on the sales document is used to find the invoice discount terms in the corresponding currency.
If invoice discounts have not been defined for foreign currencies, then the invoice discount terms in LCY defined in the Cust. Invoice Disc. table and the exchange rate on the posting date on the sales document are used to calculate the invoice discount in foreign currency.
To see existing customer invoice discounts on a customer card, choose Navigate, and then choose Invoice Discounts.
