The Age Band field does not update automatically when an employee moves into a new age range.
If an employee moves into a new age band, this field must be updated manually by following these steps
Click Employees, then click Employees.
Click Details, then click into the employee record.
Click Equality, then enter a value into the Age Band field.
If you wish for this to be an automated process, then we may be able to provide a solution via our consultancy services, which you can request via your Flexpoints.
