Typically lot numbered items are costed at average cost by location by lot - so in your outbound location look at the last item fulfillment for that lot - if there's not one, the item receipt or the work order that created the lot should have it

btw - looks like checkbox on the TO ( USE ITEM COST AS TRANSFER COST) makes no difference as to whether it picks up the transfer price or not. I notice another item I used - it wasn't pulling the Transfer Price from the item, which in my case is good. However, I can't work out how NS determines the TOs line Transfer Price - ex: I don't see where it got the 40.61 from - I don't see this on any item receipts
