Hi,
Which SP do you have on NW640? I see Note 830340 - SOAP request - Deserialisation failed. It's about Deserialisation, but the output is simular.
It says: Summary
Symptom
The call of an ABAP Web service fails. The system returns a SOAP Fault and the faultstring field has the value, "Deserialisation failed".
"Solution
You can correct the problem by importing the relevant Support Package. You cannot implement the correction in a manual way since it also requires changes delivered in Support Package SAPKB64009"
