It sounds like you are looking for a "Web Service Destination" Component inside the Data Flow Task but you will not find one there. How you might deal with it, without using a Script Component in your Data Flow setup as a Destination which might be the simplest way to go about this I think, is in your Data Flow Task capture the rows you want to send into the web service into a Variable of type Object, i.e. an ADO.NET DataTable. Then, back on the Control Flow use a ForEach Loop Container to iterate over the Variable that now contains a DataTable and call your web service using a Web Service Task inside the loop container.
