CPP2 isn’t calculating automatically

The Pensionable Earning amount in the T4 RL-1 Reporting tab of the employee record is wrong. 

1. Go to Employees & Payroll, then Employees.
2. Click the employee name to open the Employee record.
3. Click the T4 and RL-1 Reporting tab.
4. Ensure the Pensionable Earnings field for the appropriate year is accurate.

When will CPP2 start to calculate?
