Can i roll back i.e. delete a pay once I have submitted it and advanced to next period?.

Hello there, S-redman.

Yes, you can roll back a submitted pay run. Once you're done with the process, recreate the payroll, then resend the changes to the FPS. The next period will be advanced after recreating the payroll.

Please check this article with the steps: Roll back a payroll in PaySuite.
