Unpaid Leave Counting Classes for any Quota Deduction

Hi,

I have Configured Absences Like Casual Leave, Sick Leave ,Earned Leave,Maternity Leave and Unpaid Leaves.I Configured Deduction Rules for CL,EL,ML, SL and assigned to Counting Classes. I configured Counting Classes only for Unpaid Leave.but when i am trying to give Unpaid Leaves for employee, it is showing error Like

NO DEDUCTION RULE IN COUNTING CLASS 003 FOR ***** Employee on that Particular Date.Here 003 is Unpaid Leave Counting Class .Why this error came.if any one knows tell me what steps i follow

Thanks
