Dear,

I tried to generate with odoo 16 EE an invoice in ubl_bis3 format to send to customer.

I used the :

-  https://test\.peppolautoriteit\.nl/validate

\- https://ecosio.com/en/peppol-and-xml-document-validator/

to test the format

And I got this error

Schematron (XSLT) - schematron/openpeppol/3.15.0/xslt/CEN-EN16931-UBL.xslt

• Error

  Location: INV_2023_00001_ubl_bis3.xmlElement/context: /:Invoice[1]/cac:InvoiceLine[1]/cbc:InvoicedQuantity[1]XPath test: ((not(contains(normalize-space(@unitCode), ' ')) and contains(' DATAS ', concat(' ', normalize-space(@unitCode), ' '))))Error message: [BR-CL-23]-Unit code MUST be coded according to the UN/ECE Recommendation 20 with Rec 21 extension

Otherwise is there any belgian peppol test tools to verify if the format is ok ?

Best Regards,

Youssef
