When doing a day end in PurchaseOrders, it asks if you would like to do a back-up. I know you recommend doing a day end in the morning after a complete back-up has been done the night before, but if you select yes, the following files are shown to be getting backed-up:

IR*.DAT; SD*.DAT; AP*.DAT; IC*.DAT; GL*.DAT

I was wondering what happens when there are other users in any of those modules? Are the data files they are using being skipped? The back-up gives no warning.

Basically, if someone had been doing something in payables, inventory, or general ledger and a purchase order back-up has to be restored, has the other user lost what they have done?

Thanks
