Hi Venu,
while creating the material you can enter the valuation type as below
and in the Material master under accounting view 1, click on the organizationa level where youc an see your valuation type C1
In the same way you can maintain the prce for C2 and click on the organizational level under the Accounting 1 view
for the same material and same plant with different valuation types you can see different price
hope you find thd difference in price between two valuation types
revert if you need more details.
regards,
santosh
