CMN.ATO.PAYEVNT.EM14160 - Cannot process submission
We were unable to process your submission because we located multiple files to be replaced
You are seeing this error generally because there can be a delay at the ATO with recognising that they are supposed to replace a previous event.
Solution: ATO advice is to wait 24 hours between full file replacements. If this is the case just wait 24hrs then resubmit.
