When all the items have been entered on the purchase lines, you can calculate the invoice discount for the entire purchase document by clicking Functions, Calculate Invoice Discount.
If there is a check mark in the Calc. Inv. Discount field in the Purchases & Payables Setup window, the amount will be calculated automatically. Click here to learn when the automatic calculation will occur.
The discount will be apportioned over all the lines in the purchase document for items where the Allow Invoice Disc. field on the purchase line contains YES. (This is the default setting for items.)
The program uses the invoice discount terms defined in the Vendor Invoice Disc. table to calculate the invoice discount. The program uses the currency code on the purchase document to find the invoice discount terms in the corresponding currency.
If invoice discounts have not been defined for foreign currencies, the program uses the invoice discount terms in LCY defined in the Vendor Invoice Disc. table and the exchange rate as of the posting date on the purchase document to calculate the invoice discount in foreign currency.
Click Purchases, Invoice Discounts on the vendor's card to see the vendor invoice discounts that have been set up.
