I have a product A which is configurable and for this we need B which is also configurable. Now some times we sell the B also so i created the configuation profile for this. the characterstics of B are same as A but class is different. Now when i configure the A in sales order system asking to configure the B but i don't want like this. as the characterstics are common then system should take the vaules what ever entered in A. how can i avoid this siutation. waiting for ur suggestion.
