Document types

Invoices with UBL document type Invoice can be delivered in version 2.1. Credit notes with UBL document type CreditNote can also be deliver in version 2.1.

Field mapping

The special fields "order reference" and "supplier number" are mapped to specific fields in UBL. The first matching field that is non-empty will be used.

Order reference

1. /Invoice/OrderReference/ID

Supplier number

1. /Invoice/AccountingSupplierParty/CustomerAssignedAccountID - Attention: this is not a valid Peppol-Element anymore - just contained for backwards compatibility
2. /Invoice/AccountingSupplierParty/Party/PartyIdentification[1]/ID

Embedded attachments

1. /Invoice/AdditionalDocumentReference/Attachment/EmbeddedDocumentBinaryObject - is only evaluated, if the invoice is received via the Peppol eDelivery network. When using UBL on other channels, like upload or Webservice, the specific means to provide attachments must be used.
