Try just printing the RP Batch and see if you can identify the problem.

This out of balance condition was caused by an invoice which should have had six debits and one credit.  Only one debit showed up in the batch.  In trying to correct the batch, I somehow created two additional batches, so I ended up with three out of balance batches.  Using F4 in GL-P, I deleted ALL the debits, leaving only the credit.
Here's the out of balance report as it looks right now:
08/09/10  11:22 AM                                   GL OUT OF BALANCE REPORT            
 
                                           From Date:  00/00/00  Thru Date:  00/00/00

06/30/10  HEATON       #26229                                     RP 2110                                                                              3793.49          
                                                                                                                     Net Transaction:                   0.00       3793.49    
 
The odd thing is that after this invoice was entered into AP-C, it was selected for payment and paid.
 
I think I can blow away the remaining credit in GL-P and just enter the invoice again from scratch in AP-C.  I may end up with another open payable invoice, but I'll print a check to get it out of payables and then write a GL entry to fix Cash and Accounts Payable.
 
Any other suggestions?
