Hi Malathi, If you want to derive the profitability by plant and product type, you need to have a characteristic that can give such level of details. If there is no such characteristic available in your system, I would recommend to explore the usage of product hierarchy where you can define your own Product category, Product type.. etc.
That way you can easily derive your profitability at product type level as you wish.
Please let me know in case I misunderstood your requirement.
Thank you,
Srinath
