Hi,

Please share function name or logic in order to get the leave balance of employee, prior to executing the monthly leave balance accrual.

This needs to extracted for all employees for future date.

Basically we would like to know what will be leave balance of employees, by end of future month (say after 2 / 3 months down the line). 

Regards,
Mohammed G
