I wrote two manual checks on the same day to the same vendor. Unfortunately I used the same cash invoice number for both and so it wouldn't post the second check and put it in an error folder. But, it posted the check # and the amount but did not post it to the correct vendor. When I go to change the cash invoice number and enter the check number again, it says that check has already been posted. When I go into Check reconciliation it shows the check # and who it was written to and the right amount with a status of "P". How do I fix this?
