Hi Paradigm,
Thank you for your post.
We are aware that some users are getting the ATO error code CMN.ATO.PAYEVNTEMP.000389 when processing pay runs. This error is being caused by a change to the workflow and integration with the ATO's tools (connectors). We've checked and consulted further with the relevant team. However, there's been no update regarding this issue. We apologize for any inconvenience that this issue has caused you. Your patience and understanding are greatly appreciated.
In the meantime, do not declare pay runs to the ATO during the pay run process. Once a pay run is recorded, go to the STP reporting center, click on Not Sent Payrun, and then click on Send to the ATO. This will ensure STP reports are successfully sent to the ATO. For future reference, please refer to this Help article.
Please feel free to create a new post if you need help in the future. We're happy to help you.
Cheers,
Princess
