Thank you all for the detailed responses and help. I was trying to achieve using the one input form .
One errand in the title I have stated is actuals exists for previous period. My focus is for one period in time.
I want to create the report for one period of time but want to retain the actual data combination for plan as well. If I don't restrict with the combination I would end up in Cartesian product.
Sharing the row axis and hiding the actual column is one possible way for achieving the requirement.
The approach suggested by Shalini seems to be more closer to what I actually needed.
