Hi Andrew
I run Datacare every night (I have the recent version) and I have no integrity errors. However I haven't run Data integrity check on OE, I will try later. What has happened is OE created one invoice Number after another, Ie: inv# 12345, 12346. Yes, both went to AR, double the amount gets billed to the customer. However, like I said the when you query the order itself the item does not show double the amount was put through and states only 1 invoice (header page) on the order was created. When you search the invoices for that order two invoices will show up as billed against that order. This is the 2nd times I have noticed this senario and I don't know why it has happened either time. I can't see a pattern as of yet. No, I have only noticed this one other time on another order and it was about 10 days ago.
