RE: How to update the Unit Cost according to the Last Unit Cost
Hi Pollux,
As a rule, the value in the Unit Cost field on the item card is based on the standard cost for items with costing method standard. For items with all other costing methods, it is based on the calculation of the inventory available (invoiced costs and expected costs) divided by the quantity on hand.
When you sell items, the unit cost is copied from the Unit Cost field on the item card to the sales line or the item journal line.
When you purchase items, the value in the Last Direct Cost field on the item card is copied to the Direct Unit Cost field on a purchase line or to the Unit Amount line on an item journal line.

You just need to define the Costing Method as FIFO, LIFO, SPECIFIC, OR AVERAGE (which you have already defined).
If you goto the Item Card then you can check the related Ledger Entries and when you drill down the entries you can see all the transaction made on that item and according to costing method selected you will get the Calculated Cost.
