This issue occurs when newer batches in ATO Confirmed status exist, that were submitted after the batch with the errors. Because of this, the refresh batch option will be greyed out.
To allow the Refresh batch button to be activated follow the steps below:
From the Status drop down in the main Single Touch Payroll screen, selected ATO Confirmed status to see the newer batch(es).
Click each newer batch to open it, and select Options, Mark Batch as Not Required. This now enables the Refresh Batch button in the ATO Rejected batch.
Click Refresh Batch, Run Update. This will change the status of the batch to Ready to Submit.
Sign and Submit the batch.
Navigate back to each of newer batches marked Not Required, starting from the oldest batch.
Within each batch, go to Options, Reinstate batch. This creates a submission 2 version of the batch, and the status changes to Ready to Submit.
Sign and Submit submission 2 for the batch.
Repeat steps 5 to 7 for each newer batch until all batches have been re-submitted.
