If you see the error message above while running payroll validation, it means ERR pay codes were used in the previous period, but the ERR submission has not yet been sent to Revenue. This submission is necessary before you can continue processing.
To resolve this issue, follow these steps:
Generate an ERR submission and transfer an ERR submission for the previous period.
If the pay group is currently in supplementary mode, remove it from supplementary mode. Generate and submit the ERR file, then switch the pay group back to supplementary mode once the submission is confirmed. You can then continue processing as usual.
