Absence Type Planned Leave to deduct based on Calendar day not Absence day

Hi Experts,

I have scenario, where in Absence Type Planned Leave to deduct based on Calendar day not Absence day.

Example: I'm maintaining Planned Leave from 01.02.2013 to 22.02.2013.

Quota used should be 22 days (Calendar Days) but system is showing on 14 days (Absence Days).

I want it should deduct 22 Calendar Day from Planned Absence Quota.

Any body have solution for this. Pls. guide.

Ram
