Date prompt logic

Hello All,

I have a Universe object  “ Term End Date”. I want to use this as a prompt in webi report. Right now it gets all the values the "end date" has in the database.

But, My requirement is i want to use this " Term End Date” term in the prompt where I can select from current date to plus 3 years.

So the Prompt  " Term End Date" (start)  input value should be... Current date

  and to anywhere between current date to next 3 years

"Term End Date" (end) input value can be from Current date to Next 3 Years.

How do i accomplish this Universe....using current existing object " Term end date"

Any inputs Highly appreciated.

Thanks.
