Quota generation- No of days reset to zero

Hi Experts,

I run the schema to generate absence quota. Accrual period is calander year.So the values are updated in table ABWKONTI on 31st of december. But if i run the same schema again in tcode pt60  before 31st dec the value of absents quota reset to zero. Values in infotype 2006 resets to zero since the cluster table have value only on 31st december.

1. Is ther any possibility to update absence quota on 1st of jan instead of 31st dec.

2. Is it possible to read the value of abwkonti table alone for each day.

3. Is there anyother way to achive the functionality.

Thanks in Advance.
