Combining Analytic views in a Calculation view

Hello Folks,

We have created some Attribute/Analytic views and joining them in a final Calculation view. I am facing problem when combining them using join.

Here is scenario :

1. AT_MARA  : Attribute view with all the master data fields of material from MARA/MARC/MARD

2. AN_MSEG : Analytic view with Inner join of AT_MARA and MSEG table and sum of quantities based on material/plant combination.

3. AN_MBEW : Analytic view with inner join of AT_MARA and MBEW table and sum of amount based on material

4. CA_FINAL : Combine all the three view above. I have created two joins ( AT_MARA Leftouter AN_MSEG) and (AT_MARA Leftouter AN_MBEW).

I am facing problem in Union of above two joins. I have used Automap option but it is giving me multiple columns of same data.

Could you please suggest what is best way to combine the results.
