The Epicor example **InvcDtl.OurShipQty * InvcDtl.MtlUnitCost** should give you the right **cost**. Also the Epicor Fields already account for the InvcDtl.PricePerCode logic:

**InvcDtl.PricePerCode**

Indicates the pricing per quantity. It can be “E” = per each, “C” = per hundred, “M” = per thousand. Used to calculate the extended unit price for the line item. The logic is to divide the InvcDtl.ShipQty by the appropriate “per” value and then multiply by unit price. Use the OrderDtl.PricePerCode as default if referenced to an order else use Part.PricePerCode as a default. If Part record does not exist then default as “E”.

That formula would be your “Cost”. The Total Cost is Calculated using the **INVENTORY QTY and IUM NOT SALES** InvcDtl.MtlUnitCost would be based of your “Inventory UOM”

Now to get your NetUnitPrice you would do something like:

```
-------------------------------------------------
-- NetUnitPrice
-- ->,>>>,>>>,>>9.999
-------------------------------------------------
IIF(InvcDtl.SellingShipQty <> 0, (NetTotalPrice - TotalCost) / InvcDtl.SellingShipQty, 0)
```

@utaylor here are some more Notes I had of formulas:
