Lot Specific UOM Conversions

I am new to Oracle.  We are using dual units-of-measure on items.   (PRIMARY = Pieces,  SECONDARY = Pounds).

I have a sales order for this item using a unit-of-measure = FEET.

My ITEM uom conversion for this item is 1 PIECE = 500 FEET....BUT...for a particular lot, I have a lot specific UOM conversion of 1 PIECE = 580 FEET.

Note that FEET is neither the primary or secondary unit-of-measure.  When I generate the invoice for this particular lot, is it going to recognize my lot specific uom conversion and calculate the price based on 580 feet (instead of 500 feet)?

Thanks!
