The ABN was correct everywhere. I saw an older post from someone saying that they put a 1 in the branch of ABN. I did that and the next pay was accepted. A quick question though. Do I need to put the pay through for that week again or will it just be fixed by processing the other pays? It's still showing as rejected in STP Reporting. Sorry for the late reply, I've been off sick for a few weeks. STP Error CMN.ATO.GEN.20001 Hi, When finalising Payroll yesterday the error CMN.ATO.GEN.200001 (attached) appeared. When I looked at the information in Help regarding this it says it relates to an ABN error. I have followed their instructions and I have checked our details, ABN, Software Id etc in both MYOB & at the ATO and all is correct. Is anyone able to help? I was on hold with MYOB for 2.5hours yesterday before they hung up and then another 2.5hours this morning before being hung up again. Thanks for any help, it's much appreciated Bec
