Hi,
Still having a doubt on your query but let me clear.
I think you are running jan payroll from 01.01.2014 to 31.01.2014. In this period only 15.01.2014 to 31.01.2014 day's annual leave will be taken by the system and full payment or partial payment would be paid accordingly.
But you want to pay him upto 14th Feb2014 and once he will come from the leave then he will be received remaining balance for the Feb2014 month. Am i correct?
Regards,
Sankarsan
