Good to know @PhilMcIntosh I was thinking about the Generate PO button on SO Entry, where you don't get these options to set the Unit Cost. On a Drop Ship, the Unit Cost is ""what every you have typed"" into the SO Line as the unit cost. Even if you set the Drop Ship Line Item Unit Cost to $ 0.00; that is how it posts when you invoice that line of the order; it does not use the PO Unit Cost, it does not use the item ""last cost"".
