The WSDL defines the operation signature of the web service you want to run. When you import a WSDL, the Developer tool creates a physical data object that you can reuse for other transformations.

A WSDL can define multiple operations. When you create a Web Service Consumer transformation, select which operation you want to run. You can view the operation input and the operation output hierarchies in the Web Service Consumer transformation. The hierarchies define the structure of the SOAP request message and the SOAP response message.

You can also import a WSDL with one-way input operation. You must create dummy output ports when you import a WSDL with one-way input operation.
