The Input transformation represents the input element and header elements in the web service WSDL. The Input transformation receives the SOAP request from the client. It parses the XML message into groups of relational data and passes the data to other transformations in the operation mapping.
The Developer tool creates the Input transformation when you define the operation input for a web service.
Use the Input transformation
Ports
tab to view the operation input hierarchy, define output ports, and map data from the operation input to the output ports. The operation input hierarchy defines the SOAP request message hierarchy.
You can map the complete SOAP request as XML instead of returning groups of relational data in separate output ports. When you map the SOAP request as XML, the Data Integration Service returns the complete SOAP message in one output port.
