90 % payment of receipt of goods , 10 % at receipt of documentation R12 ebiz

Hi

we have the following scenario where goods are ordered at the supplier but the supplier is paid

- 90 % at the delivery of the goods

and 10 % when the documentation is delivered

(supplier needs to deliver the necessary certificates etc so only when he has done that he will get fully paid)

BUT eg if the price of the good is 100

as this is a buy item the cost of the item is also 100

so we cannot say the price is 90

and our documentation is 10  (in case you would say .. create a po with 2 items - 1 with the inventory item and one with a documentation item0 as then the cost of the item is not correct)
