Often (though not always) we get an out of balance error when we attempt to process a customer refund. When we go to AR-M and create an AP Voucher for the refund amount, we find that the A/P Credit side shows up on the out of balance report, but the A/R Debit side of the entry is missing. I don't want to post a one-sided A/R entry because then it doesn't feed through to the subsidiary ledger (and the balance still shows as a credit balance on the customer's statement).
 
If I delete the A/P Credit entry from the out of balance report, it only removes it from the batch upload - it still shows up as a payable. And the customer's credit balance still exists on their statement. If we re-do the customer refund, it will move the customer's credit balance to A/P, but then the A/P balance owed to the customer is double what it should be.  
 
1). What can we do to prevent this from happening? 2). What is the best way to undo one-sided entries and attempt to reprocess? 3). What should I do to remove the extra payable showing up in A/P?
 
(We have a similar issue with posting transactions when we receive vendor invoices for items in PO RNI. Only the A/P Credit side shows up, the Debit to PO RNI is missing. We correct this by doing a one sided Dr entry to PO RNI, but I worry this sort of entry will not feed through to the proper Vendor subsidiary ledger. We have considerable difficulty getting the PO RNI report to tie to the Balance Sheet so its hard to assess the impact of these entries).
