We have had several seemingly related issues over the last couple months.
 
First one:
Vendor had two invoices due. Picked both to pay. Printed check - stub shows both invoices and proper total.
Went to do another check run and a check was printed for one of the invoices. A/P check history only shows the other invoice being paid.
Most strange about this one was that at one point an A/P history showed the one recorded as being paid as if it were a credit, i.e. "Check total is negative"...
 
Then we had another one:
Single invoice, marked printed, keeps showing up in future check runs.
 
Then we had a batch of three of them
Three different vendors
This time I noticed that the check register showed the three checks, but all with $0.00 amounts.
 
Yesterday I discovered one more. This because I was surprised that the bank balance was showing as high as it was, so I ran a check register and found that a $25k check was not showing up...
As in the first instances, I tried doing a new selection in AP-F and re-printing. I also, per Lynn's recommendation, reinitialized BKAPCHKF, then re-picking and re-printing.
The only was I was able to register the fact that I had written the check was to use the E-Pay function in AP-F
 
Anyone else seeing similar problems?
 
I'm using T7 version of AP-F with banner date of 7/9/13. All updates and patches had been run as of last week some time (I re-ran patches yesterday but there was no mention of anything related to AP).
