Mapping problem with XMLRPCServer


We are using an XMLRPCServer to be able to call a Webservice from a Natural program. This XMLRPCServer use a .xmm mapping file.
The call to the webservice is working fine, but the return mapping raise an “XML Runtime Exception 2000 0077 Unknown document, XML Runtime can not interpret the incoming document”.
We have activated the trace of the XMLRPCServer but the trace is only returning the RPC data flows

Question: Is there a way to trace the mapping SOAP->RPC ?

Thanks for your help,


please see how to enable XML/SOAP related tracing.
