  Hi icapilla,
  
  I have several examples in order to call a external WS from Navision in Dynamics NAV 2009 R2 version. I based in this fantastic post :http://blogs.msdn.com/b/freddyk/archive/2010/01/22/connecting-to-nav-web-services-from-microsoft-dynamics-nav-2009-sp1.aspx
  
  This is the code from my general function (InvokeNavWS).
  
  // Create XMLHTTP and SEND
  CREATE(xmlhttp, TRUE, TRUE);
  xmlhttp.open('POST', pURL, FALSE);
  xmlhttp.setRequestHeader('Content-type', 'text/xml; charset=utf-8');
  xmlhttp.setRequestHeader('SOAPAction', pMethod);
  RutaRQ := TEMPORARYPATH + 'Request' + GetFechaHora + '.xml';
  xmldoc.save(RutaRQ);
  xmlhttp.send(xmldoc);
  
  // If status is OK - Get Result XML
  RutaRS := TEMPORARYPATH + 'Response' + GetFechaHora + '.xml';
  IF xmlhttp.status=200 THEN BEGIN
  xmldoc := xmlhttp.responseXML;
  xmldoc.setProperty('SelectionLanguage', 'XPath');
  xmldoc.setProperty('SelectionNamespaces', 'xmlns:tns="' + pNameSpace + '"');
  
  //Save Response
  xmldoc.save(RutaRS);
  //BigResponse.ADDTEXT(xmlhttp.responseText);
  //SaveResponse(BigResponse);
  
  IF pReturnTag <> '' THEN
  pNodeList := xmldoc.selectNodes('//tns:' + pReturnTag);
  
  result := TRUE;
  END ELSE BEGIN
  xmldoc := xmlhttp.responseXML;
  
  //Save Response
  xmldoc.save(RutaRS);
  //BigResponse.ADDTEXT(xmlhttp.responseText);
  //SaveResponse(BigResponse);
  
  xmldoc.setProperty('SelectionLanguage', 'XPath');
  xmldoc.setProperty('SelectionNamespaces', 'xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"');
  
  pNodeList := xmldoc.selectNodes('//s:' + 'Fault');
  result := FALSE;
  END;
  
  
  Regards.

  JAJ good morning!, And above all thank you very much for answering so fast.
  
  I have a question, I think my problem is with the call to web services.
  
  The three most important lines of this code are:
  
  
  Xmlhttp.open ('POST', 'http://www.asmred.com/WebSrvs/b2b.asmx', FALSE);
  XmlHttp.setRequestHeader ('Content-type', 'text / xml; charset = utf-8');
  XmlHttp.setRequestHeader ('SOAPAction', 'http://www.asmred.com/GrabaServicios');
  
  In the first line, I can take the url and insert it in an internet explorer and takes me to the page corresponding to a set of web services, but instead n the third, not a mistake or if so, the function which I call queiro called "GravaServicio" if I enter this url in internet explorer, does not lead anywhere, so if you can not be wrong ...
  
  I may be missing some kind of hotfix, or the automation utulizando is incorrect, at this time use the following:
  
  XmlHttp -> 'Microsoft XML, v6.0'. XMLHTTP '
  XmlDoc -> 'Microsoft XML, v6.0'. DOMDocument '
  
  Tine do not know if anything to do, but some sites I have come to see the following:
  
  Xmlhttp.open ('POST', 'http://www.asmred.com/WebSrvs/b2b.asmx', FALSE, 'User', 'Pass');
  
  Maybe it's this ... in any case I also tried getting the same error http, the wonderful Error 400: BadRequest.

  Hi icapilla,
  
  I think that the correct call is (more or less):
  
  Xmlhttp.open ('POST', 'http://www.asmred.com/WebSrvs/b2b.asmx?op=GrabaServicios', FALSE);
  XmlHttp.setRequestHeader ('Content-type', 'text/xml; charset = utf-8');
  XmlHttp.setRequestHeader ('SOAPAction', 'GrabaServicios');
  
  
  Let mi know if is correct.
  
  Regards and good luck.

  Look, it seems that some progress has been made, now generates a reply with the following error:
  
  
  System.Web.Services.Protocols.SoapException: Server did not Recognize the value of HTTP Header SOAPAction: GrabaServicios.
  
  The error status is 500: Internal server error, the error is no longer 400.
  
  While making the call now, you do not see concrete webservices, seeing this, it may be because it has several versions, and somehow I have to say the specific version I throw?
  
  The truth is the first time I'm doing this and I are removing years of life.

  Hi, try with this:
  
  Xmlhttp.open ('POST', 'http://www.asmred.com/WebSrvs/b2b.asmx?op=GrabaServicios', FALSE);
  XmlHttp.setRequestHeader ('Content-type', 'text/xml; charset = utf-8');
  XmlHttp.setRequestHeader ('SOAPAction', 'http://www.asmred.com/GrabaServicios');
  
  regards.

  This SOAPAction does not generate the return xml and returns a status 400 Bad request.
  with how easy it is seen in the examples, do not know why is taking so much problems.
  
  Don't know what else I can try ...

  Hi everybody.
  
  If WebService parameter is typeof string, add <![CDATA]<xml string>]]>
  
  http://www.codigonexo.com/blog/cajon-de ... d-request/
  
  locautXmlHttp.send(
  '<?xml version="1.0" encoding="utf-8"?>'+
  '<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"'+
  ' xmlns:xsd="http://www.w3.org/2001/XMLSchema"'+
  ' xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"&gt; '+
  ' <soap:Body>'+
  ' <syncIncidents xmlns="http://company.crm.org/">'+
  ' <strXML>'+
  ' <![CDATA[<Params>'+
  ' <crmGuid>"2BB1F227-6ECD-420B-9217-CB006F6787B3"</crmGuid>'+
  ' <codBarras>"31047620000011"</codBarras>'+
  ' </Params>]]>'+
  ' </strXML>'+
  ' </syncIncidents>'+
  ' </soap:Body>'+
  '</soap:Envelope>'
  );
