Pricing??

Hello Friends,

Need some help with pricing, we have 7 different materials for which pricing is defined separately for condition type PN00.Also in the sales deal we have defined SPA (Net price agreement) for these 7 different part no.for example

Part A $100

Part B $200

Part C $300

Part D $400

Part E $500

Part F $600

Part G$700

Now the requirement is if the customer buys all 7 parts then they should get SPA pricing, but if they decides to buy only Part A & B then they should get PN00 price. I am not sure how we can define in SAP for special pricing to be applied only when all 7 parts are purchased if not then regular price PN00 should be applied,

Appreciate your advice and suggestion to meet this requirement.

Thanks in advance.

Mike
