Error when uploading STP file - invalid company info provided and ABN, Company name and branch number do not match those in Reckon GovConnect. Rang the helpdesk, have checked that all company info details are correct, have re run the file and uploaded, however still facing the same error.
Haven't got the answer for you but if it helps I discovered that our NZ bank sort codes 00-0000 were being rejected (failing validation) by the system because it expected 000-000. We moved the hyphen and all was ok. Is it possible you have a similar problem (i.e. number correct but format wrong)?
