Error Faced while calling WSDL using Call Web Service

Question

Hi, 
 I am facing an error while using Call Web Service. It shows me a warning saying "The operation utilizes encodings which are usupported". 
 It shows no operations found in the selected endpoint, which i think is happening because of the warning. 
 
 The WSDL is running fine when tested using SOAP UI tester. 
 Is anybody aware about such error. Any help will be appreciated.

There are certain Web Services that Appian doesn't support. Take a look at docs.appian.com/.../Call_Web_Service_Smart_Service.html for more details. It's possible the service you're calling falls on one of those types.

1) To support Carlos Answer your WSDL includes this 
 <soap:operation soapAction ="" style =" rpc " />

<soap:body use =" encoded "

2) In the Link Carlos sent you can find this Note: 
 " NOTE : RPC/encoded service styles are not supported, and instead you must use RPC/literal or Document/literal encodings. If you know the WSDL is valid, and you receive an Invalid WSDL exception" 
 
 3) Finally Seems like you are using Blueprism: 
 "RPC/Literal, RPC/Encoded and Document/Literal based web services are supported, and Blue Prism can support both complex and simple data-types using mappings to Blue Prism data items and collections (which support nesting)"

 So, just use a different service style.
