Hello Dagna2309, thanks for posting on the Community page, If you want to change the enrolment date you will need to delete payroll back to when the employee started and correct this then run the payroll forward again. If you are unsure how to do this you can ring the support line on 0808 234 5337 the line is open mon to fri 8am to 7pm and you will be able to set up a screenshare with the agent on the phone.
