PO price condition based in good receive

Hi ,

I have a request from the bussiness about material pricing. I have one fee to be payed by load not by quantity or % is a fixed value by load.

Material price = 10 + 3 for which load. So if I have a PO with qte 100 and I receive in 4 good receive or for loads. The final price will be:

100 X 10 + 3 x 4 = 1000 + 12 = 1012.

Any idea how I can config this?

tks
