I, too, am noticing that the inventory value of some Products, even though 0 Qty in inventory, has a value.  These products were even 'deleted' made inactive without issue.  The suggestion was made to go to tine Inventory Starting Value > Edit and Save; however, we cannot do this when the inventory starting value was in a previously closed period ... or even in a different year.  Are there any other options to adjusting the value?
