Def - Cost - Actual
The Actual Cost reflects the cost that will post to the General Ledger for Items with a 'Costing Method' of "Active". For some items this may be set from a default or "standard" cost rate and for other items this may reflect that actual amount paid to purchase or incurred to produce the product. For each individual LotSK, this is calculated as the [Actual Base Cost Rate] + sum of all the [Actual Cost Layer Rates].
