Hello expert,
I am calling web service provided by AXIS in ABAP but error occur when processing response part.
The web service is used to create material master in JAVA AXIS system.
After setting up the LP in soamanager then make a call, we got an error saying
"GENERAL_ERROR Error duing proxy processing (PART
UNKNOWN (NULL) ) "
I looked at the full trace in soamanger, the call is executed successful, and the data are inserted in the remote system.
response payload can be seen in the trace
Request payload

For me it looks it is an issue in the response payload that ABAP proxy can not process it.
such as, the response payload NS prefix is soapenv, other than soap-env in request payload...
but i am not sure, whether this is the root cause.
Could you help me to find out what is going wrong here?

Answer 1

the response payload NS prefix is soapenv, other than soap-env in request payload
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" is equivalent to xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/" . Namespace defined correctly.
I can also see that response is correct (assuming "S" denote success):
<CreateITEMReturn>S</CreateITEMReturn>
Also check type of WSDL style usually this error occurs if you are using RPC/Encoded style WSDL, modify wsdl for Document/Literal style (as RPC style WSDL not supported by ABAP proxy), see this discussion here: Cleint Proxy error
