Unit cost default values

The default values of unit costs are determined in this order:
  1. Direct entry on document
  2. Item Location if the company is a standard costing company
  3. Last received or invoiced cost

When you manually create a unit cost on the document, you can override any other costs for that item. If your company is a standard costing company, then the unit cost default value is from the Item Location. If neither of these is true, then the cost default is from the last received or invoiced cost. If the item has not been received or invoiced, then you must manually create a cost for that item.
