Quota not updating for the next year

Hi

2.5 days of Annaul leave has to be generated in the each month end. Also it has to be prorated and on LOP the quota should reduce.I have done this by standard config.

Now I have to carry forward the quota whatever is remaining to next year. I have used the following pcrs. I have created time type 8001.

assigned in the pcr.

But last year quota is not adding upto next year. It is showing separately in 2006. Can some one tell me what other steps I have to do. previous year quota should add up to current year quota.

I have checked sdn, but did't get the appropriate one.Need help.

Regards
