On the pre-check report, the amounts for each vendor is a positive amount and none of the forced invoices have been partially paid. However, the manual cheque I printed the other day was a partial payment and I had to enter the amount I wanted to pay on that particular invoice but that's all I changed. This is the first time since the manual cheque that I've tried to print another one.

I am looking under our Company Profile, under the System Options tab and I do not see anything that says "Set Amt Payable to Inv Balance" or anything similar there. I did check a couple of the vendors profiles under Pay Control when I click on one of their invoices and there is a maximum payment box there and the amount there is at 0.00.
