Hi Leo4 and CCBell
Thank you for your posts. Welcome to the MYOB Community Forum.
Apologies for the delay in responding. This error can show if you have an employee who was terminated and then rehired, you will need to remove the termination date on your employee's profile under Employee Details and under the Employee Termination Tab in STP Reporting Centre. If you're still receiving this error, please let me know and I'll be glad to assist you further.
Please let me know if you have further enquiries and I'll be happy to help.
