Using WebService served by SAP

Question

Greetings,
I have been stuck trying to get CF 8 to talk to SAP serviced Web
Service. Here is code I am using:
<cfscript>
   ws = CreateObject("webservice", "http://xxx.xxxxx.com:8002/sap/bc/
srt/rfc/sap/Z_ZRFC_TEST?sap-client=235&wsdl=1.1");
   xlatstring = ws.ZZrfcTest(Rfcin = "Hello");
</cfscript>
Here is WSDL file
<?xml version="1.0" encoding="utf-8" ?>
- <wsdl:definitions targetNamespace="urn:sap-
com:document:sap:soap:functions:mc-style" xmlns:wsdl="http://

I am still strugling even with parsed XML attribute however I am not ready investigating WSDL2Java yet...
Here is how parameters are described in WSDL
- <xsd:element name="BAPI_PO_GETDETAIL1">
     <xsd:complexType>
-           <xsd:sequence>
           <xsd:element name="ACCOUNT_ASSIGNMENT" minOccurs="0" type="tns:char1" />
           <xsd:element name="DELIVERY_ADDRESS" minOccurs="0" type="tns:char1" />
           <xsd:element name="HEADER_TEXT" minOccurs="0" type="tns:char1" />
           <xsd:element name="ITEM_TEXT" minOccurs="0" type="tns:char1" />
           <xsd:element name="PURCHASEORDER" type="tns:char10" />
           <xsd:element name="SERVICES" minOccurs="0" type="tns:char1" />
                <xsd:element name="VERSION" minOccurs="0" type="tns:char1" />
          </xsd:sequence>
     </xsd:complexType>
</xsd:element>
Here is how char1 is described
- <xsd:simpleType name="char1">
    -<xsd:restriction base="xsd:string">
           <xsd:maxLength value="1" />
     </xsd:restriction>
</xsd:simpleType>
Here is how Char10 is defined
<xsd:simpleType name="char10">
    -<xsd:restriction base="xsd:string">
           <xsd:maxLength value="10" />
     </xsd:restriction>
</xsd:simpleType>
This is one of the versions of the code I tried
<cfsavecontent variable="sXML">
    <BAPI_PO_GETDETAIL1>
      <ACCOUNT_ASSIGNMENT/>
      <DELIVERY_ADDRESS/>
      <HEADER_TEXT/>
      <ITEM_TEXT/>
      <PURCHASEORDER>4500000059</PURCHASEORDER>
      <SERVICES/>
      <VERSION/>
    </BAPI_PO_GETDETAIL1>
/cfsavecontent>
<cfset xmlObj = XMLParse(sXML)>
<cfdump var="#sXML#">
<cfinvoke
      webservice="http://xxxx.xxxxxxxx.com:8006/sap/bc/srt/rfc/sap/Z_PO_GETDETAIL1?sap-client=330&wsdl=1.1"
      method="BAPI_PO_GETDETAIL1"
      refreshWSDL="yes"
      username="web_service"
      password="Seneca09"
     <!--- argumentcollection="#xmlObj#" --->
      returnvariable="aReturn"
>
      <cfinvokeargument name="BAPI_PO_GETDETAIL1" value="#xmlObj#">
</cfinvoke>
Any ideas what I am doing wrong? Any suggestiong or tips?
