Analityc - Key Figure for calculate number of days.

Hi All,

I would like to know if there is any way to calculate on a key figure how many day pass from a specifyc date to the dayToday.

The idea is to have a report some like:

i.e:

Date KeyFigure 1

11/09 5 (11/09 - 16/09(date today) )

I could'nt find any funtionality for this.

Is this possible?

Regards
