Reporting period from &1 to &2 is invalid

What causes this issue?

The First Day Worked <LB>&V1&</> and the Last Day For Which Paid
<LB>&V2&</> were invalid, and therefore did not pass the ROE validation
check. For an ROE to be valid, the First Day Worked must precede or
fall on - but not follow - the Last Day For Which Paid.

System Response

ROE processing for this employee is terminated.
The ROE Workbench resumes processing with the next employee.

How to fix this error?

Review HR Master Data for the employee to verify the accuracy of the
employee's First Day Worked and Last Day For Which Paid.
If these dates are inaccurate, then correct them in HR Master Data.
After you have corrected the dates, return to your previous activity
and attempt to perform it again.
If these dates are accurate, or if you cannot resolve the error as
indicated above, then report it to your System Administrator.
