dmaguire: in my experience you should always assign a customer/vendor to AR/AP lines on journals. If you don't, depending on the volume of the data migration journals, other reports might slow down. I'm assuming those journals are just ins and outs. What you can do is create sunny customer and vendor that can be assigned to those lines. Then mark those periods as 'Allow Non GL Changes". Then either assign the customer/vendor manually or create a small script to do that for you. Then you'll be able to go into the customer/vendor payment screen to close them off against each other. Keep currency revaluation in mind in case of exchange rate differences.
