Basecone can only process UBL versions 2.0 and 2.1.
The XML and PDF are seen as one file (a UBL-invoice). If you receive the error message “failed” because Basecone cannot read the XML, the PDF will not be send to the company for processing either (when sending 1 XML and 1 PDF file, in 1 email).
A XML-file must meet certain conditions in order to be processed by Basecone. More information about the delivery and processing of UBL invoices, click here.
If you want to know why Basecone cannot read the XML, you can ask Basecone Support. Send the XML to basecone.support@wolterskluwer.com.
