The problem is how to construct the xml body. I have tried to call the standard web service, save the result of the node input in a pv, use the toxml function on This pv and pass the result as body of the advanced wsdl call webservice, setting the other required parameter but the result is also an error</p><div style="clear:both;"></div>https://community.appian.com/thread/67642?ContentTypeID=1Mon, 24 Jun 2019 16:49:27 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:7ce005f4-340f-4dfe-b1f5-34ed850090f4RajHasti<p>What are the errors you are getting while using advanced call web service.
