Dynamically Hide columns

Hi All,

Here there is one scenario I have faced while working with Webi Report

there are total 24 columns in my report

JAN, FEB, MAR.........up to  DEC of 2014 and

JAN, FEB, MAR................up to DEC of 2013

I need to hide some columns based on user input.

Suppose User gives 5- 2014 then he should get data like JAN to MAY 2014 Columns and MAY to DEC 2013 Columns and remaining Columns need to Hide.

Can any one suggest me how to work on this issue in WEBI?

Thanks & Regards,

Siva Sravan.
