AR clerk informed me that when she ran Check Register on yesterday's deposit, it was missing one of the checks.  Upon investigation, I found that the SO invoice in question is no longer showing in AR Aging, but it is also not showing up on Customer Payment History Report.  It has just vanished.  In addition, when I printed unposted GL transactions, DBA had posted the transactions for Sales Commissions and backing out invoice from AR, but there was no posting to Cash account so GL was out of balance.
 
I posted a JE to Cash to put GL back into balance, but I have no idea how to get the invoice to show up on the Cust Pmt History Report.  Clerk states that no error messages were displayed nor any indication that transaction was incomplete.
 
Has anyone else had this happen?  An suggestions on how to get the SO Invoice to appear on the Pmt History Report?
 
Thanks!
