Materials replication from ECC to C4C through HCI

Dear experts,

I am working on materials replication from ECC to C4C through HCI. When I use standard .wsdl files, everything is fine but when I use custom .wsdl file from ECC (get by SRT_IDOC_WSDL_NS report), I have following errors in WE02 & in HCI.

No matter what I do, I still get the same errors. Do you have already face this errors? Any ideas would be appreciated.

Thanks in advance.

Best regards.
