In my company, we deducted salary of an employee in hourly. If a person is required to complete 180 hours a month and he completed 178 so 2 hours will be deducted from a pay, for example; if a person salary is 30,000/22(working day) so 1 day salary is 1363 so 1 hour is 151.51 so equals to 2 hour 303.03 rupees will be deducted from salary. how can I function this in payroll deduction?
