CFED_CPP_METHOD (Canadian Federal Canada Pension Plan Method) is an optional field used to indicate the override for CPP calculation: period exemption or an hourly exemption.

• The period exemption method is used for employees who are paid a relatively consistent pay period amount, for example, salaried or full-time hourly employees.
• The hourly exemption method is used for employees whose pay amount fluctuates significantly from period to period, for example, part-time hourly or casual employees.
