Creating a Debit Memo for an A/P Transaction
Debit memos for A/P transactions that originated in purchasing must be made in purchasing. So, if you currently have a voucher in A/P Posted Transactions, follow these steps:
Note: Never enter a negative voucher on the A/P Vouchers and
Adjustments form to create a debit memo for Accounts Payable. A debit memo
can be tied back to a voucher, but a voucher cannot be tied back to another voucher
(regardless if one is negative).
