Forum Post: unit cost to finish good item(standard cost) is 0

I have one item as finish good.When i make production order to this item i see item cost in this production order in output is 0 from value entry table .

I go to item card i see unit cost is 0 to all transactions that made before. Now i want to change cost from 0 to 210

Are using revaluation journal will do that OR using standard cost work sheet

thanks
