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.

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.
