Due Date not calculated for Sales Credit Memos where Payment Terms does not have a Payment Disc. Calculation (Discount Date Calculation field is blank) and therefore the field Calc. Pmt. Disc. on Cr. Memos is not ticked.
This is an annoyance to the client as because of this issue the Customer Ledger Entries for Sales Credit Memos always show in RED and BOLD, i.e. look as if they are Overdue.
