Leave - Carry Forward

Hi All,

In our company we have three type of leaves.

PL, CL & SL. In addition we have Compensatory Off.

Now my requirement is :

1. I need to configure system in such a way that only PL <= 10 should be carry forwarded to next year.

2. A employee can take only 2 CLs in a stretch.

3. A employee can take only 3 SLs in a stretch. If it is more than three days he need to produce MC.

4. Probations can take only 1PL, 1/2 SL & 1/2CL per month.

5. If a employee takes 10 days continous and if it includes sat/sun or any other public holiday even that should be counted.

6. If a employee works additional day and later takes compensatory off, no leaves should be deducted.

How can i configure them in system?

Thanks in advance.

Regards,

Raj
