Issue Difference between costs we see and NAV displays

If i buy something at $10 and sell it next month day and apply charges for $2 after two months and my automatic cost adjustment is set to week. Then cost anticipated by client or accountant will be different from what NAV displays reason this charge has been accounted in COGS by the time u do not run Adjust cost.

So what will be impact on Inventory Valuation

Qty 1 Value 10 Month I
Qty 0 Value 0 Month II
Qty 0 Value 2 Month III

Unfortunately everything is picked up from ILE so this diff makes sense. But it is always calculated correctly.
