I face the same problem. Maybe you can use Vendor code to match the invoice and credit memo.
We use Vendor code to match items.
My problem is the invoice and credit memo is in different period.
example:
credit memo - PO GR date is in 2014.10.10.
invoice-PO GR date is in 2014.11.09.
our accountants using the GR date to select the items, maybe in NOV,they set the date between NOV. 01 to 30 . The credit memo cannot be select. They insist on the period they set.
How can i select all credit memo ,and set limit to invoice?
