In order to facilitate the understanding of the structure of the CFE our system provides a functionality to issue "manual" documents from the testing environment and to be able to visualize the XML format corresponding to the CFE entered. This allows you to quickly relate the items entered in the manual invoice and corroborate the location of the values entered in the corresponding XML.
To be able to do this you must:
Create Invoices manually throw the option "CFEs Emitidos".
Access throw the visualization option to the detail of the CFE.
In Testing environment will see an "XML" tab to view the representation of the XML of the CFE.
The XML tab will not be showed if the created document has validation errors.
Repeat this process for each CFE type that will use and all variations of contents on each one to be able to recognize the variations of the XML representation.
