You cannot delete a payroll schedule that has employees assigned to it. Before you delete a payroll schedule,
Reassign all the employees who're assigned to this payroll schedule to another payroll schedule
if you decide not to use payroll schedules at all, delete the schedule assignment from the employee's record.
You can always make a payroll schedule inactive instead of deleting it. This way you could always make it active again if you needed to do so, without setting up a new payroll schedule.
To do this task
Open the Payroll Schedule List window.
Click the Payroll Center icon. From the Pay Employees section, click the Related Payroll Activities button and then click Add or Edit Payroll Schedules.
Click to select the payroll schedule you want to delete.
Click the Payroll Schedule button and then click Delete Payroll Schedule.
Click OK to confirm the deletion.
