With Incoming files Peppol XML files can be processed but there are blocking errors should be fixed by the user:
Incoming document have a sub-page with errors/warning but till now I haven't seen a warning.
Issue 1: if the xml file has a company name which is not 100% equal to the company name: then a blocking error will occur.
issue 2: same goes for the company address
issue 3: a different VAT registration no. is in xml file is used (KVK / Chamber of Commerce) instead of the VAT no. which is also not always found in the xml and the vendor can not be found.
Issue 4: the VAT number is not shown in sub page Incoming Document (189)
Issue 5: vendor mentions a Unit of Measure code which is not in the database (and you do not want in your database). A mapping table would be useful.
Issue 6: Checks on Receipt lines or Return Shipment Lines are not executed!
Issue 7: Additional Document; if the XML file contains an additional reference in PDF file, the pdf file is not automatically imported as Supported Attachments.
