Let's say that we have a vendor that has 2 different codes assigned when entering invoices, 80% for one line and 20% for the second line. In the older version FE, when entering an invoice let's say that the 80% line is not exactly 80% and you have to write the amount manually from the invoice line and for the second line if you write 0, it gives you the remaining balance down below in the little window to fill out the second line. In the NXT version it does not calculate the difference for you.
