Actual cost calculation
i have Oracle financials ver 11.5.10 in my company. i need to know how actual cost is calculated in mtl_material_transactions table.
here are some transactions against an item sorted by last_updated_date..
transaction_type_id transaction_qty transaction_uom primary_qty trans_date actual_cost transaction_cost prior_cost
