Hi Guys,
After having implemented the Nfe 3.10 pre-requisites and notes ( I hope that you have used the KBA "2056762 - Guidelines for NF-e layout 3.10 SAP Notes installation" ) you'll be challenged by the changes required to use the new layout version. To ease this work we have created the KBA "2057942 Guideline for NF-e layout 3.10 implementation in ERP and SAP NFE".
We hope that this information can help you to avoid issues and identify the changes quickly.
Regards,
On behalf of Renan Correa
