If the benefit effective period year lies between two years, then a payroll calendar should be set for both the years or it will be considered an incomplete calendar. A payroll calendar is complete if it contains details spanning between the first benefit effective start date and last benefit effective end date.
Additionally, the payroll calendar should be set for all the payroll frequency types present in the census so that cutoff date logic can be implemented for all the employees. If the payroll calendar does not contain details for a particular pay frequency, then the payroll deduction calculations will be done on the basis of the default paycheck schedule for that frequency.
