If you made a mistake in a processed pay, you need to reverse either the whole pay or individual lines in the pay. To do this, you enter an adjustment pay, not a timesheet pay. The option to reverse a whole pay only exists in the adjustment pay screen. Additionally, doing an adjustment pay gives you the flexibility to enter in dollar value line totals. See: Adjustment Pays.
If you need to reverse a pay from a previous financial year, do the reversal (the Adjustment Pay) in that end of year historical payroll company.
To Reverse a processed pay:
Identify the Pay Number, Pay Period Ending Date and Date Paid of the original pay. See: Find a processed pay to fully or partially reverse this pay.
Enter an adjustment pay to reverse the incorrect pay or line:
To reverse a pay in full, see: Reverse a processed pay transaction in full.
To reverse single lines in a pay, see: Reverse single lines in a processed pay transaction.
Process the new pay as usual. See: The Payroll Process Pays Workflow.
