Hi, I have a Report requirement to have Web Services as a Datasource. The Service is a secured one. So it requires SOAPHEADER to be passed along with the query. I have the current query as : <Query> <SoapAction>http://location.company.com.au/services/GetLocation</SoapAction> <Method Namespace="http://location.company.com.au/services/" Name="GetLocation"> <ServiceAuthHeader xmlns="http://location.company.com.au/services/"> <Username>userLocator</Username> <Password>123456789</Password> </ServiceAuthHeader> <Parameters> <Parameter Name="typeID" Type="integer"> <DefaultValue>2</DefaultValue> </Parameter> </Parameters> </Method> <ElementPath IgnoreNamespaces="true">*</ElementPath> </Query> I tried adding <soap:Header> tag in the query but it gives error Please let me know the way to pass the SOAPHeaders with the above SSRS query. PS: Through Fiddler the following Request works fine and response is provided. <?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/"> <soap:Header> <ServiceAuthHeader xmlns="http://location.company.com.au/services/"> <Username>string</Username> <Password>string</Password> </ServiceAuthHeader> </soap:Header> <soap:Body> <GetLocation xmlns="http://location.company.com.au/services/" /> </soap:Body> </soap:Envelope> Thanks in Advance - M.
