With lot tracking set up properly, your inventory valuation report should reflect the sum of actual qty at each specific unit cost receipt.
The inventory valuation is the sum of the value entries. Even with FIFO costing, if your lot tracking is correctly setup, the fifo cost is not actually used, the specific cost of the the specific lot is taken as COGS which leaves the inventory valuation correct.
Open up the item tracking code page that you have assigned to the item. If you are tracking inbound, outbound and internal transactions, your costing should be correct.
If it isn’t, what is your inventory setup? If cost posting isn’t automatic, you may have a slight delay in costs being updated but they will be correct when adjust cost item entries and post costs to g/l are run.
