Is it possible to have specific identification costing method for Lot Numbered Inventory? I have set the costing method to Lot Numbered in the item record but when I fulfill it, the COGS is still the average cost. Ex. 1st Purchase of 1 unit = $300, 2nd purchase of 1 unit = $400. Sold the 1st unit which should have COGS of $300 but the result was $350 which was the avg of the two purchases.

If you have the method set to lot based costing it's specific average of that lot
