Policy plugin is not exporting all of the properties associated with soap services correctly, When exporting a soap service the following checkbox of 'Allow requests intended for operations not supported by the WSDL' as seen on the wsdl tab is not being carried across to the destination gateway.
This is expected behavior as there is a functional gap in exporting the service with all of its details. In this case, the policy plugin exporter is not counting on the Service/ServiceDetails/SoapMapping/Lax element path from the RESTMAN service definition.
This setting will need to be manually enabled on the destination host once imported.
