How to get count of days for months from a date field in webi

Hi All,

I have a "Full_Date" column in database which displays all the business days.

How to get the count of business days per month wise using formula / variable ?

Ex:

Jan_Business_Days = 22

Feb_Business_Days = 21

March_Business_Days = 22

Any suggestions would be appreciated.

Thanks,

Rameez Shaikh
