Rhoice:

Attached is a screenshot of the detail of one such customer.  All transactions for this customer are General Journal entries.  If I choose to receive payment for this customer, the "invoices" (in this case, just journal entries that debited the A/R account) do NOT appear on the Customer Payment screen, and therefore I cannot apply the credits.

As the title of this thread implies, I am trying to apply General Journal entries that debit the A/R account ("Invoices") to other General Journal entries that credit the same  A/R account ("receipts" or "credits").  I cannot simply delete the entries and recreate the activity as invoices and receipts; the activity is very old and the corresponding cash receipts have been reconciled in the cash account.

How can I apply the General Journal entries against each other to clear them from the A/R aging?
