Reduction Rules after 1 month of Unpaid Absence

Hi Friends,

I'm looking for a solution for the below issue:

The issue : Annual Leave is based on accrual method and Time Unit is "Hours". . This leave quota should not get accrued when an unpaid leave is applied for >=1 month.

My Config is as follows:

1. Accrual Period is - Daily

2. Transferred to Quota - by end of Time Evaluation period.

Reduction Rule config:

------------------------------

Reference Period : Accrual Period

To Percentage : No Reduction

From Percentage : Proportionate reduction

Reduction indicator for Unpaid Absence : Ticked.. Now, the problem is - when I specify 30 days in Min. field, still system is generating Annual Quota..

Not able to understand where I missed the config.. I tried changing Accrual period to monthly, but still it didnt work. Can any one help me please?

Thanks,

Geetika
