Re landed cost some comments

#1 You can enter landed costs to the receipt several days after the
receipt. If using average it can wrongly recalculate the material
burdern but would be ok for last. Except in the time from the receipt
entry to the landed cost update last material burden would be zero.

#2 Some suppliers give invoice with goods and the receiving guys
could action those that have charges on them.

#3 You cannot enter a % material burden on the part master if you
also want to use landed costs for the item.
