Material Price and Cost Report

Hi Friends,

I have

EKKO ( Purchasing Document Header )

EKPO ( Purchasing Document Item )

EINA ( Purchasing Info Record - General Data )

A017 ( Material Info Record ) Tables

Now i want to fetch

STPRAS ( Standard Price )

PEINH ( Price Unit )

fields from MBEW ( Material Valuation ) Table

Can any one tell me How to Link MBEW Table from the above Tables ?

Points for Sure......
