Bex Issue Query

Hello, I have a query about Bex.  I have 2 Bex Queries with different Keyfigures on different providers.

Query 1:

Customer     Material     Plant     Quantity Sold

Query 2:

This is what i want to do.  Basically I want Query 1 to run Query 2 and look for material in query 2 and then if found in positive then return me plant and Quantity Available. I think it is possible with replacement path but i don't know how it is possible. Can some body help me please?

Thanks.
