The Releve 1 List window contains an employee table with columns displaying the amounts and other items that will (or did) appear on the employee's Releve 1 slip. The total row at the bottom contains most of the information required to complete the Releve 1 Summary form.
The table can be set to display amounts for any year by changing the T4/Releve 1 Reporting Year on the payroll settings window.
You cannot edit the values in the table as they are the totals of amounts posted to the employee's earnings and deduction accounts. You can, however, edit the employee's name and social insurance number.
