Удаление listmember из маркетинговых списков

[Kipetcoff]

получилось примерно следующее

var oXmlHttp = oService.CreateXmlHttp();
				oXmlHttp.open("POST", oService.server + "/mscrmservices/2007/crmservice.asmx", false);
				oXmlHttp.setRequestHeader("Content-Type", "text/xml; charset=utf-8");
				oXmlHttp.setRequestHeader("SOAPAction", "http://schemas.microsoft.com/crm/2007/WebServices/Execute");				
				
				var sXml =
				"<?xml version=\"1.0\" encoding=\"utf-8\"?>" + 
				"<soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\">" + 
				"<soap:Header>" + 
					"<CrmAuthenticationToken xmlns=\"http://schemas.microsoft.com/crm/2007/WebServices\">" + 
						"<AuthenticationType xmlns=\"http://schemas.microsoft.com/crm/2007/CoreTypes\">0</AuthenticationType>" + 
						"<CrmTicket xmlns=\"http://schemas.microsoft.com/crm/2007/CoreTypes\"></CrmTicket>" + 
						"<OrganizationName xmlns=\"http://schemas.microsoft.com/crm/2007/CoreTypes\">MicrosoftCRM</OrganizationName>" + 
						"<CallerId xmlns=\"http://schemas.microsoft.com/crm/2007/CoreTypes\">00000000-0000-0000-0000-000000000000</CallerId>" + 
					"</CrmAuthenticationToken>" + 
				"</soap:Header>" + 
				"  <soap:Body>" + 
				"    <Request xsi:type=\"RemoveMemberListRequest\" xmlns=\"http://schemas.microsoft.com/crm/2007/WebServices\">" + 
				"      <ListId>107FA1EB-5911-DF11-A5B3-0003FF966666</ListId>" + 
				"      <EntityId>0020590A-37D0-DC11-AA32-0003FF33509E</EntityId>" + 
				"    </Request>" + 
				"  </soap:Body>" + 
				"</soap:Envelope>";
				
				oXmlHttp.send(sXml);

Ошибка soap:ServerServer was unable to process request. 0x80040203 request Platform
Если не смотреть на ID..в остальном правильный ли запрос?
