By external webservice I mean the webservice which are hosted from the foreign system other than the system in which we are trying to consume the webservice. Let me take the example from the internet by using a freely available Illustration Lets open the website http://www.webservicex.net/ws/default.aspx from where we take the wsdl specification of a freely available webservice currency convertor.   Consuming the External Web Service in SAP Environment SAP COMMUNITY NETWORK SDN - sdn.sap.com | BPX -  bpx.sap.com | BOC - boc.sap.com | UAC - uac.sap.com © 2010 SAP AG 4 Now lets see the XML specification of the Currency Convertor Webservice and we can easily make out that multiple bindings are present with the multiple ports. Lets keep the operation <wsdl:operation name= ConversionRate > and the respective binding <wsdl:binding name= CurrencyConvertorSoap  type= tns:CurrencyConvertorSoap > and the   respective port <wsdl:port name= CurrencyConvertorSoap  binding= tns:CurrencyConvertorSoap > I mean copy the WSDL file and edit it in a notepad. keep the parts which are mentioned above and remove the following. Finally save it with the extention “.wsdl”.   <?xml version= 1.0 encoding= utf-8 ?>  -  <wsdl:definitions xmlns:soap= http://schemas.xmlsoap.org/wsdl/soap/  xmlns:tm= http://microsoft.com/wsdl/mime/textMatching/  xmlns:soapenc= http://schemas.xmlsoap.org/soap/encoding/  xmlns:mime= http://schemas.xmlsoap.org/wsdl/mime/  xmlns:tns= http://www.webserviceX.NET/  xmlns:s= http://www.w3.org/2001/XMLSchema  xmlns:soap12= http://schemas.xmlsoap.org/wsdl/soap12/  xmlns:http= http://schemas.xmlsoap.org/wsdl/http/  targetNamespace= http://www.webserviceX.NET/  xmlns:wsdl= http://schemas.xmlsoap.org/wsdl/ >  -  <wsdl:types>  -  <s:schema elementFormDefault= qualified  targetNamespace= http://www.webserviceX.NET/ >  -  <s:element name= ConversionRate >  -  <s:complexType>  -  <s:sequence>  <s:element minOccurs= 1  maxOccurs= 1  name= FromCurrency  type= tns:Currency /> <s:element minOccurs= 1  maxOccurs= 1  name= ToCurrency  type= tns:Currency /> </s:sequence>  </s:complexType>  </s:element>  -  <s:simpleType name= Currency >  -  <s:restriction base= s:string > <s:enumeration value= AFA /> <s:enumeration value= ALL /> <s:enumeration value= DZD /> <s:enumeration value= ARS /> <s:enumeration value= AWG /> <s:enumeration value= AUD /> <s:enumeration value= BSD /> <s:enumeration value= BHD />
