Is there an easier way to delete all stock qtys/values for all inventory LOT numbered items?

I'm guessing deleting all their transaction history isn't an option

thanks Kevin, I was thinking the same initially to decided whether delete all the inventory adjustment records or do an import, good thing is the inventory has not been used in any transactions so just deleting the IA would work.

Can always use the Inventory Worksheet for lot and serial items for setting the qty's to zero. Via a csv import still, but you don't have to stuff around with specifying lot numbers (and bins) if you're setting to zero
