This modification provides for additional tracking of credit memos. Standard Traverse allows you to apply credit memos to invoices and correctly tracks balances both on the credit memo and the invoice it was applied too, but it does not provide a good trail of where the credit memo was applied. This is especially true if one credit memo is applied to several different invoices or if multiple credits are applied to one invoice.
We modify both the Post Transactions and the Split/Reapply function to put the credit memo number into the Payment No field in the Open Invoice table.
The last part of this modification is to change the AR Statement to show this same information. We now print the Payment No field (which holds the credit memo number) instead of the PO number for credit memo records.
