Fault Message : Mapping error

Hi experts,

Here is my scenario : SProxy => PI => SoapUI

It's a Synchrone interface.

I have some difficulty with Fault Message.

com.sap.engine.interfaces.messaging.api.exception.MessagingException: com.sap.engine.interfaces.messaging.api.exception.MessagingException: SOAP: Response message contains an errorXIAdapter/PARSING/ADAPTER.SOAP_EXCEPTION - soap fault: Fault String here ... at com.sap.aii.adapter.soap.web.SOAPHandler.processSOAPtoXMB(SOAPHandler.java:772) at ...

Response from SoapUI (Fault Message) :

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">

   <soapenv:Header/>

   <soapenv:Body>

      <soapenv:Fault>

         <faultcode>Fault Code here ...</faultcode>

         <faultstring>Fault String here ...</faultstring>

      </soapenv:Fault>

   </soapenv:Body>

</soapenv:Envelope>

I created a MT for my Outbound interface fault message (SProxy - ECC) :

.

It's a standard Fault Message.

For SoapUI response i tried to create an External Definition with a custom XSD :

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"

xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"

targetNamespace="http://schemas.xmlsoap.org/soap/envelope/">

    <xs:complexType name="BodyType">

        <xs:sequence>

            <xs:element name="Fault" type="SOAP-ENV:FaultType"/>

        </xs:sequence>

    </xs:complexType>

    <xs:element name="Envelope">

        <xs:complexType>

            <xs:sequence>

                <xs:element name="Body" type="SOAP-ENV:BodyType"/>

            </xs:sequence>

        </xs:complexType>

    </xs:element>

    <xs:complexType name="FaultType">

        <xs:sequence>

            <xs:element name="faultcode" type="xs:string"/>

            <xs:element name="faultstring" type="xs:string"/>

        </xs:sequence>

    </xs:complexType>

</xs:schema>

But i have always this error :

I tried to use http://schemas.xmlsoap.org/soap/envelope/ in external definition but same problem.

Soap Envelope in External Definition :

Here is my mapping :

I don't understand why i always have this error ...

Maybe my External Definition doesn't match with SoapUI response ?
