Public Holiday and work schedule generation

Hello Experts,

i have a floating public holiday on 15.02.2011, so i inserted this date in the public holiday which is already assigned to the holiday calendar, and i generate work schedules in batch till 122020. but still when i view the work schedule in IT0007 on the 15.02.2011 the day type is still "work/paid".

could anyone advice on this please???
