Sponsoring UBL Invoice-2

Feature Sponsoring

As invoice is “printed” when invoice is posted, report invoice could be added as attachment in the ubl peppol bis 3 file. Here’s an example with a report saved as pdf file (still needs improvements).

Adding a property to convert report in base64 in account_invoice/invoice.py

class Invoice(metaclass=PoolMeta):
    __name__ = 'account.invoice'

    @property
    def base64_report(self):
        if self.invoice_report_cache:
            return (base64.b64encode(self.invoice_report_cache)).decode('ascii')

In edocument_ubl/template/2/Invoice.xml:

…
<py:if test=“specification == ‘peppol-bis-3’ and this.invoice.base64_report”>
<cac:AdditionalDocumentReference>
<cbc:ID>${this.invoice.number}</cbc:ID>
<cbc:DocumentType>${this.invoice.invoice_report_format}</cbc:DocumentType>
<cac:Attachment>
<cbc:EmbeddedDocumentBinaryObject mimeCode=“application/pdf” filename=“invoice.pdf”>${this.invoice.base64_report}</cbc:EmbeddedDocumentBinaryObject>
</cac:Attachment>
</cac:AdditionalDocumentReference>
</py:if>

For me it is a matter to use the European tax identifier instead of the local tax identifier on the invoice.
Now I do not know how I could enforce this except by removed national identifier from the tax identifiers (but it is not backward compatible).

I seems it should be at least one of <cbc:BuyerReference> or <cac:OrderReference> / <cbc:ID>.
I guess for <cbc:BuyerReference> we could fill with the Invoice.reference if filled.
And for <cac:OrderReference> / <cbc:ID> it should be the origin but the problem is that Tryton may have multiple origins.

The last revision should fix all the comments and include the invoice as additional document.

Thanks Cédric !

One last error when testing peppol-bis-3 file:

[UBL-CR-666] A UBL invoice shall not include an AdditionalDocumentReference simultaneously referring an Invoice Object Identifier and an Attachment

So <cbc:DocumentTypeCode>130</cbc:DocumentTypeCode> is not needed when there is an attachment.

I really do not understand the rule. One more rule that does not make sense for me.

47

Indeed. Don’t understand too :slight_smile:

48

As far as I understand despite the documentation for <cbc:DocumentTypeCode> saying that the default value is 130 (which was the reason I set it to this value).
This code 130 seems to indicate that the document is not attached but just providing via the <cbc:ID>.
