it should be possible to update the cost price by updating the pack price,
for example we recieve a box of 12 gels the invoice is for a box of 12 but currently we have to divide the box price to get the cost price, this makes no sence as the MPQ is already there for the purchase order to divide the pack cost to update the unit,
(This could also work for line price)
at the very least until CL have adopted this can make the fields read only that can't be saved, currently you can highlight /edit them but not save the change
