in jde there has been some vouchers were discounts were taken even though the voucher was paid after discount window (later then 20 days, DD0 pay terms). Please see two snips of vouchers. Invoice dates were 20 and 25.08 but both were paid on October 1st and discounts were taken (paid after 20 days of invoice date). Suppliers have complained about short paid invoices. Why discounts were taken? Thanks!
