When a Journal Entry is made and associated to a Customer Account it shows up on their AR Aging. You can then make payments to it as if it were an Invoice and/or use it to make payments to an Invoice as if it were a Payment. If you do not clear the entire amount, it will show up with a "Balance" on the AR Aging, and on the individual form when Viewing the Transaction. I am able to pull these transactions via a TransactionSearchBasic, but the result list does not contain a column with the amountRemaining,or the unapplied amount
