Error while trying to call a web service in a process model

I am trying to connect to a web service by providing WSDL URL from a process model smart shape. The WSDL is accessible smoothly over browser but when tried from Appian it throws below error and also the service endpoints are not listed.

The endpoint WSHttpBinding_ISETUP contains a reference to an ExactlyOne policy operator which does not contain a supported policy alternative. That endpoint is not available for selection. The unsupported policies are [[alternative 1 : UsingAddressing]]. (APNX-2-4041-007)

Please help on this regard.

Seems like this web service uses some XML structure which is not supported OOTB. Check docs.appian.com/.../Call_Web_Service_Smart_Service.html

Thanks Stefan. Could you please help me with any other alternative approach to use such services.

Sometimes it is possible to modify the WSDL to make it compatible. In case the XML is small and/or simple, you can use an integration and create the XML from a template.
