Hi,
I've fixed that issue, but I am sure this is not the standard way SAP would suggest but unfortunately I've got no other hints, how to get the wright WSDL file for the Z-IDOC out of the On-premise System. So I've manipulated the file from the report SRT-IDOC_WSDL_NS in order to remove the targetNamespace from it. Now it works and i can exchange Z-Fields from On-Premise CRm to C4C.
Unfortunately I'm still facing the issue mentioned above, that I'm not able to produce a Z-IDOC in the other way (C4C --> CRM). What do I've to do to get also Z-IDOCS in the inbound direction. Outbound is always a Z-IDOC. I've added the Z-IDOC to the partner profile in WE20 but it is still a Z-IDOC produced. Is there something i have to do in HCI? Maybe someone has already experience with exchanging Z-Fields over HCI?
Thanks for any Information and best regards,
Markus
