Why does the payslip display payments for a later payroll period?

These reports include the payslip and Payroll Register Report. The payroll period with the latest date earned is used in reports to display the combined payment results. This means you submitted a prepayments process that includes payroll calculations where the date earned of a calculation falls in a different payroll period.

For example, you process a QuickPay for a person on a weekly payroll. The date earned for the QuickPay is 7 November, which falls in the first payroll period. You decide to include the QuickPay payment in next week's payroll, which has a date earned of 14 November. The payslip that includes the QuickPay will show the combined results of the QuickPay and the regular pay as of the second payroll period.

To generate reports and payslips for the payroll period the date earned occurs, process prepayments separately for calculations where the date earned falls in an earlier payroll period.
