I'm trying to implement a v18 Enterprise Odoo server for managing the company's accounting, is hosted on a Windows server.

There is just one last thing I need to do to be able to certificate with the chilean internal revenue service (SII), and that is generating an electronic invoice settlement, document type 43 (factura de liquidacion electronica).

When you install the chilean localization packages, all documents needed to operate according to chilean law are created, but I don't know why, document 43 is lock. I was able to unlock it, so I can use it now, bet every time I send the DTE to the SII, the document is rejected under the error "invalid schema".

When using Altova XMLSpy to inspect the XML file generated by the DTE, the schema is invalidated because the tag "SiiDte:TpoDocLiq" is supposed to be used instead of "<NmbItem>", problem is, I don't have any button or option to add the document I'm supposed to reference at the tag "SiiDte:TpoDocLiq".

What I'm doing wrong?
