Thanks Omid,
Now the public holiday is counted in It2001-Payroll days.
My current work schedule -> 8.5 hours a day.
When i apply leave in IT2001 from 01.05.2013 - 02.05.2013,
Cal days = 2
Payroll days = 2 days (including public holiday on 01st may)
Absence hours = 8.5 (the working hours on public holiday is not added. how to update? via config / custom logic)
Regards,
Dhiyu
