Continuous Calculation enables you to distribute your payroll processing throughout a payroll period. You can run processes such as the payroll run, prepayments steps, and costing, which deal with predominantly static employee data, at the start of the payroll period, leaving more time for validation and correction of changed data.

Continuous Calculation works by using triggers. You define triggers and events which inform the system when data has changed. For example, if an employee receives a bonus, the corresponding event is triggered. When you subsequently run the Continuous Calculation process, the system identifies these triggers and marks the corresponding payroll processes (such as the payroll run) to be repeated. The affected processes are repeated in a batch process which can be run as often as required. You define the frequency of the batch process when you run the Continuous Calculation process.
