XSLT: Remove Envelope from WS response into SAP

Hello experts,

First of all, believe me I've been searching for a few days already and have tried way many different variants, but I still get an error message when testing from SAP side using SPROXY.

I'm working on a Synchronous scenario with a WebService that uses Envelope for Request and Response. Request seems to be working fine. Before using a custom Message Type MT_FacturasPendientesResp, I managed to get a response in SPROXY but still with a different error message.

The funny thing is when testing the XSL mapping in ESR works fine and I get the expected result. The error I get when using SPROXY is as follows.

Probably there's something I can't see, but seems some kind of misunderstanding perhaps namespaces?. Can anyone see any big mistakes?

Please advice.

I appreciate any help to solve this issue.

Thank you for your time.

Patricio.

Error testing Service Interface in SPROXY

Operation Mapping

I remove all namespaces with this template.

Output.xsl

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
xmlns:ns0="http://xxxxxxx.com">    <xsl:output indent="yes"/>        <xsl:template match="@* | node()">        <xsl:copy>            <xsl:apply-templates select="@* | node()"/>        </xsl:copy>    </xsl:template>        <xsl:template match="/">        <xsl:apply-templates select="@* | node()"/>    </xsl:template>        <xsl:template match="*">        <xsl:element name="{local-name()}">            <xsl:apply-templates select="@*|node()"/>        </xsl:element>            </xsl:template>    </xsl:stylesheet>

Then I try to build the same structure in MT_FacturasPendientesResp as in ESR

Output_2.xsl (namespace used here is same as MT in ESR)

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"
 xmlns:p1="http://xxxxxxxxxxxxx.com"><xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>  <xsl:template match="/">  <p1:MT_FacturasPendientesResp>     <respuesta>    <items>    <factura>     <xsl:for-each select="Envelope/Body/consultarFacturasConSaldosPendientesResponse/respuesta/items/factura">      <nroFactura>      <xsl:value-of select="nroFactura"/>      </nroFactura>     </xsl:for-each>           </factura>    </items>    </respuesta>    </p1:MT_FacturasPendientesResp>     </xsl:template></xsl:stylesheet>
