Pass Query Filter values to an object

[sa0309]

I've created an Object, DaysDiff, within BO Universe Designer. The object consists of calling function, f_DaysDiff.

DaysDiff:
f_DaysDiff(b_date,e_date)

From within BO Infoview, I want to be able to pass my "Query filter" daterange to DaysDiff.

Query filter:
i_date between '01-Jan-2012' and '31-Jan-2013'


I want to pass '01-Jan-2012' as b_date and '31-Jan-2013' as e_date to function f_DaysDiff. Ex: f_DaysDiff('01-Jan-2012','31-Jan-2013')

Is this possible?

Any comments and or suggestions would be appreciated.
