I tried the filter, but it does not seem possible to filter in such a way to report the inventory summary on a specific day in the past. There are only three dates fields that can be adjusted in the filters. "last recieved" and "last sold" and "creation date." All three of those dates fields will define inventory of interest, but none of them stop the clock. The report still covers everything that happened to the date filtered inventory all the way up to today. This would not be a problem, I would not need the inventory summary, if the inventory valuation report actually reported on all of the inventory, which it doesn't.
