Hello, 

I would like to find a solution (by coding or using an actual module) to automatically change the purchase order price if the customer is changed.

Ex : Product A available in 2 suppliers S1 and S2 .  Price for product A in S1=4€ and in S2=3.50€
My first request was with supplier S1, so I can see price 4€.

If I change the supplier to S2, actually, the price will not be changed automatically.

When You have a PO with 300 order.line, it is a problem....You have to modify 300 lines...

Any idea please ?

thanks for Your precious help :o)
