SAP C4C - How to calculate Number of Working days between two dates ?

Hi Experts,

Is there a way to calculate number of working days between two dates in SDK ?

Duration = Date 2 - Date 1 gives me the duration in days while I would like to know this duration in working days.

It seems there is no way to specify WorkingDayCalendarCode.

Your inputs are highly appreciated !

Thanks & Regards
