AR Invoice

I have Epicor 10 and have run into an issue where I have two AR Invoices for the same customer One is 8.00 and the other is -8.00 so netting together they are 0. The issue is I havent been able to apply one to the other to clear off the aging. Has anyone else had this issue and how do you handle it. We have a number of instances like this that arise.

I assume that Apply Credit Memo is not functioning for you?

that did not work for this. But we used write off and adjustment and that worked

Did the customer show up on the aging report, but with $0 owed?

And was the one for -$8 actually a CM for a positive $8?
