Every once in a while, since we upgraded to GP2010, an ACH batch will go directly to posting when our AP person processes the batch after it's been approved. She never gets the chance to print remittances or anything. The main issue with this, is that the payments go through with a blank check number. Normally when it happens (maybe once a month?) we void the blank payments, and process the batch again, and it goes through fine with normal "check" numbers. Today, unfortunately, it happened twice in a row, and we're at a bit of a loss.
We use MICR, and it's been suggested that may be the problem, but i'm not sure of any setup issue that could cause this.
