If you have already run a magnetic report and must make changes to the data, you must do the following:
Roll back the report.
Make all necessary changes to employee data, and mark those employees for retry.
Retry the Year End Pre-Process, and rerun the magnetic report.
Note: If you are adding employer-specific data that was previously missing, you do not need to roll back the Year End Pre-Process before rerunning the magnetic report.
Roll back a process from the Submit Request window.
To roll back a process for a magnetic report, you can run the Rollback US SPWL process. See: Running the Rollback US SPWL Process
Note: The rollback process does not have any effect on the four files produced by the Magnetic Report process. However, when you rerun the process following a rollback, the new process produces four files that overwrite the existing files.
