Hi Venu,
If you want two diff pricing procedure for two diff sales doc type.
You should use different doc. pricing procedure .
I do not understand why you are using same doc pric proc for two pricing procedures.
In standard PRicing procedure determination you have to maintain Sales are, Doc prc proc. and cust. pric. proc.
You ahve to take one of the above as diff to allow two pricing procedures for diff order type.
Hope this clarifies.
