On the 18th of this month, our assistant treasurer entered 8 invoices into the Accounts Payable module, then printed the checks and mailed them out. This week, she entered the new batch of bills due, but when she went to print them, all the open invoices from the 18th still showed as not having been printed. I had her de-select those that had already been paid so she could just print the checks actually needed and giving me time in an incredibly busy week to try and figure out what the problem was.
This morning, when I printed the Open Items report, those invoices from the 18th showed up on the report with "Pay Now" set to "no", and no sign of the computer generated checks that had been printed. I went into Maintain Computer Generated Checks and searched for the first missing check number with no luck.

So, how could this have happened
