How do I include an employee with a retroactive rate change calculated by the Generate HCM Rates process, in Retropay?
You can track retroactive rate changes for an employee, and include the employee in the Retropay process.
 The Generate HCM Rates process calculates rates for employees. In some instances, the
            rate change can be due to a retrospective change such as a backdated salary award for an
            employee, or a late change to a values defined by criteria. You can use events to track
            all employees who have a retrospective rate change calculated by the Generate HCM Rates
            and raise retro event notifications. To set up this feature, you need to add the
                Pay Rates Event entity to a retroactive event group.
    Note: Only a single element per employee is required to track the retroactive rate
                    changes for each payroll period. For this reason, it's recommended that you add
                    the event group that includes the Pay Rates Event entity
                    to a limited number of recurring elements, such as salary elements.
