Holiday Calender issue

Hi ..

We have create a calender from 112007 and placed 11/12/2007 as holiday. We have generated all the Work schedules to reflect the new calender from 112007.

But when i went in PA61 and looked at the weekly schedule for a person who belongs to the calender, it shows that 11/12/2007 is not a holiday.

I looked at all the configuration and looks absolutely good. Pls let me know why it is not shown as Holiday ?

Thanks

Shyam
