While reviewing closed SO's for the year, I discovered an SO that was invoiced last month that did not get posted to Sales when it was closed.  GL transactions showed the deposits against this SO were applied and the costs were posted to COGS but no posting to Sales.
 
The SO was for a system that was never completed but the customer paid in full for the work done.  The amount of the invoice was on Line 1 under the part number Deposits.  Thinking maybe the invoice (2470) had just not been posted, I re-opened the SO, released the lines and tried to print a new invoice.  DBA told me there was no invoice to print and none to post.  Next I tried to void the original invoice (2470) but DBA tells me there is an unposted invoice (2488) pending against the SO and it will have to be posted before trying to void any invoices that originated from the SO.  I cannot find any invoice 2488.
 
I am in a loop here.  Does anyone know how to fix this?

The GL-D journal is not out of balance.  Something did go to A/R but nothing went to Sales.  Following is a summary of the journal (there were actually two deposits and I have left out the Inv/COGS entries which aren't relevant to this issue):
 
Sales Tax Payable............................................................9,836
A/R..........................145,498
A/R - Deposits Applied..................................................145,498
Deposits...................145,498
Customer Deposits.......................................................135,662
 
The deposits are not in the Customer Deposits file any longer and there is no entry to Sales.
 
The extended price on the invoice was $145,498, but the total was $0 after the deposits were applied.   Does this DBA consider this to be "giving it away"?
