Sharepoint Web Services I cannot see anywhere in the documentation on how t

@Mike, I was referring to the standard SharePoint web services, not the Appian.SharePoint.Lists.asmx?wsdl, which is from the Appian service assembly add-on. Stefan suggested posting a SOAP message to an endpoint that looks like it is from SharePoint's standard out-of-the-box web services, and just looking at the SOAP message, I don't see any reason that Appian Call Web Service smart service wouldn't be able to send that same message. There may be something tricky about the WSDL that I'm missing though.
