Composite Provider with Inner join and assignment to the same infoobject from 2 ADSO

Dear Experts,

I have a query regarding the Composite Provider with Inner join and assignment of the infoobject.

There are 2 ADSOs used in the composite provider with one Key combination on Company code.

There 0Calmonth in both the ADSOs and I want assign the 0calmonth from both the ADSO.

Whenever I am creating the assignment from ADSO, 0calmonth is created twice, 1 from one ADSO, the other from another ADSO.

I am getting error when checked.

How to fix this issue?

Also is it possible to map the same infoobject from both ADSO similar to Union?

Thanks,

Jagadeep.
