Shared leave quota

Hi Gurus,

I have a requirement where I have to configured a leave quota which is shared between 3 different types of leave (Privilege,Casual and Sick). Could you please let me know how what all configuration steps is needed to achieve this.

I am using negative time management and using TM04 schema for time evaluation. Also I would like to know how do I can configure

the carry forward behavior of leave, to develop a better understand I have an example:

An employee gets 10 leave as entitlement every year in the month of January and if he don't consume all the 10 leave then 2 leave will be carry forward to next year and next year his entitlement will be 12 leave (10 leave [current year] +2 leave [carry forward from previous

year]).

Quick responce will be appreciated.

Regards,
