Variable Creation on user entry FISPER

Hi All,

I need help to design a BEx Query , currently I am facing a challenge. The client require the report query design as per the screen shot.

Hence I have

1. I have calculated YTD using 0P_FPER (User Entry Value).

2. But the rest figures , I need to display over the periods , for example user entered 003.2009 , the Key Figure should be displayed under three column 001 till 003 and YTD Key figure in single column cumulative of all three periods.

3. Please help as I am unable to create variable which will give me 002.2009 and another variable 003.2009 ..

The number of column should be dynamic in nature depending upon user entry.
