Business days instead of Calender days in Deadline Monitoring - Reg

All,

I have a requirement for using the Business days instead of calender days in the Deadline monitoring. I was wondering if anybody came across such requirement and how to fulfill this. I searched the forum to get related threads, but not got so helpful ones. But, i remember seeing some settings (Not sure if it's in Deadline job scheduling or SWU3 or general Workflow / SAP Business workplace settings), there was an option of the check box "Calender days". But, not able to find it now.

Anybody, Please let me know if this is possible and if yes, how.

Thanks in advance
