Why is the 'Verify employee details' option disabled when attempting to submit STP ?

The 'Verify employee details' option is disabled when trying to submit STP because the pay run for the specific period has not been closed off yet. STP submission requires the completion of the pay run for that particular period.

Once the pay run is closed off, the 'Verify employee details' option will become available, allowing you to successfully submit the STP report.

Please ensure that you check the pay run status for the specific period before attempting to submit the STP, as it is necessary to wait for the pay run to be closed off for that period.
