If you use the Incoming Automation Solution for Nota Fiscal / Conhecimento de Transporte you might be facing some rejection when doing the status query for CT-es with XML layout 1.04 on step CTEAUTHO. Or, when doing a status query for a CT-e issued with layout 1.04 on the outbound scenario. This is happening because since June 1st SEFAZ only deal with XML versio 2.00 for CT-es. So, now, if you need to do a status query this request, even if the CT-e was originaly created with XML layout 1.04, should be done with XML layout 2.00.
So, we have created SAP Note 2035711 – Usage of CT-e Status Check (layout 2.0) for older versions. With it, all requests for status query will be send with XML layout 2.00 and you will be able to continue the process.
