I’m in the process of migrating an integration from SAP PI to SAP CPI. For this, I imported the existing EHF schema into CPI, re-did the mapping and ensured everything is now inside CPI. But there's an issue, the XML result generated by CPI is different from the one generated by PI.

Here’s an example of the XML result from CPI:

    <CustomizationID>urn:fdc:peppol.eu:poacc:trns:order_response:3:extended:urn:fdc:anskaffelser.no:2019:ehf:spec:3.0</CustomizationID>
    <ProfileID>urn:fdc:anskaffelser.no:2019:ehf:postaward:g3:09:1.0</ProfileID>

And here's the result from PI:

<ns0:OrderResponse xmlns:ns0="urn:oasis:names:specification:ubl:schema:xsd:OrderResponse-2">
    <ns1:CustomizationID xmlns:ns1="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2">urn:fdc:peppol.eu:poacc:trns:order_response:3:extended:urn:fdc:anskaffelser.no:2019:ehf:spec:3.0</ns1:CustomizationID>
    <ns1:ProfileID xmlns:ns1="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2">urn:fdc:anskaffelser.no:2019:ehf:postaward:g3:09:1.0</ns1:ProfileID>

In the PI XML, the namespace is included for each element, but in the CPI result, it’s missing.

The missing reference is causing the file to not be validated by the EHF validator.

Has anyone else encountered this issue before?
