Subset validation artefact creation service

Crane Softwrights Ltd. now offers a packaged service to create subset UBL schemas and other validation artefacts.  The publicly-available tools used by Crane are the same tools used by the UBL Technical Committee to create the validation artefacts in the UBL distribution.  Clients can use the public tools on their own or contract Crane to invoke the tools with a client's specification of their subset of UBL (accomplished using a shared online spreadsheet).  Details are found at the URL below.

Timeout importing xsd files from UBL 2.1 in SAP ECC6

Hello everyone,

We have currently problems importing the UBL2.1 xsd files into SAP ECC6 through transaction SPROXY.

I know recommendation by SAP is to use their EAI (XI, PI, PO) to make the mapping between sap structures and UBL structure but is there no possibility to import it directly into SAP backend system?

The problem is the processing time is very long and leads to timeout. Even when extending timeout, files are then loaded (after 1 hour) but the proxy transaction in SAP takes 20 minutes for each action.

Seminar: UBL E-invoicing, a daily practice

Utrecht, Netherlands
7 Dec 2016
Event Type: 

Agreement on syntaxes complying with the forthcoming European standard (EN) on Electronic Invoicing

Thomas Fillis reports from Barcelona:

CEN/TC 434 unanimously agreed to endorse UBL and CII as the syntaxes complying with the forthcoming EN and to be listed in a specific CEN Technical Specification (TS). Once the EN and TS are published by CEN and referenced in the  Official Journal of the European Union (OJEU), contracting authorities and entities in the EU will have to receive and process electronic invoices which comply with the EN and any of the two syntaxes, in accordance with the provisions of Article 7 of Directive 2014/55/EU.

Australia choses UBL for whole-of-economy eInvoicing

This news article is the latest update on the Australian whole-of-economy eBusiness framework. 

The officially specifications will be published in the next few weeks at http://digitalbusinesscouncil.com.au. The article omits the fact that the PEPPOL-developed OASIS standards for business discovery (SMP and SML) are also being used.

Several of the council’s members were already working on bringing the standards to life with an aggressive timeline as early as this coming September.

Invoice schema does not import correctly

Hi folks

I'm working on PEPPOL/UBL for a customer, and have downloaded the 2.1 UBL schemas. The UBL-Invoice-2.1.xsd does not import correctly - there's a missing dependency for the http://www.w3.org/2000/09/xmldsig#:Signature element. That's in the UBL-xmldsig-core-schema-2.1.xsd file, which is not imported

I tried adding the UBL-SignatureAggregateComponents-2.1.xsd file as an import, as that in turn imports the xmldsig namespace, but that's still not working. A check of a couple of the other maindoc schemas suggests that this is a general problem.
