Dynamic parameter creation problem

[dev777]

Hi,

I want to create dynamic parameter for Time Period like,

Time Period Type
Time Period Value

Time Period Type--> Rolling12Months
--> YearToDate
--> Quarter

Time Period Value --> It should show list of date values

If "Rolling12months" is selected then the time period value should show
"2010"
"2009"
"2008"

If "YearToDate" is selected then it should show todays date to first date of this year i.e.,
"03/04/2010 - 01/01/2010"
"03/04/2009 - 01/01/2009"
"03/04/2008 - 01/01/2008"


If "Quarter" is selected then it should show
"Q1"
"Q2"
"Q3"
"Q4"

Any answer to this will be highly appreciated.
I think this should be done in business view manager. Not Sure.

Please reply ....

Thanks
