prorating IT0014

Dear Friends,

Requirement is to prorate IT0014 (payroll India), Now the rule I have written is

ZSPL (Attached with P0014)

*

M281 Birth Day Allowance

WPBPC for all WPBP

This rule is prorating IT0014 in case of employee joins in mid month but in case employee leaving in the mid of same month the same is not working....

Employee Joins 15 th May - Leaving 18 th May (Presently the rule is calculating 15th May to 31st May)

Please suggest...

Thanks in advance............
