pricing

hi pls can any body solve my problem, its urgent. its like multiple pricing for a same product

scenario is . client is automative spare parts manufacturer. item in stock carries different prices. This is because of the statutory requirement to sell old material at old price and new material at new price. it is not applicable for some customer groups. so in sales order when customer order 5 pcs out of which if 3from old material and 2 from new material pricing should be different for old and new material.during delivery. delivery split should happen because here packing and invoicing should be done separately for old and new materials.

pls any body guide me how to proceed from order to invoice (in img, if possible detailly)

pls urgent my email id is krishe53@rediffmail.com

will reward points

regards
