Absence Types Issues.

Dears ,

             Good Day ,

              i have some cases in the absence types and time management

              if you can help me and give me advise

1. Employee WS from 8:00 to 16:30 and has absence type

        0.5 day regular leave and 0.5 day casual leave , the system calculated 2 absence day !

        Note : it is deducted correctly from the quota.

2. when apply over time compensation (IT 2007) - Double Days Off -

    this work correctly and increase quota but generate else time wage type (2 days from basic Salary )

    How can force the compensation to increase the absence quota only .

Thanks and Best Regards ,
