Input Relational Ports and the Overview View
To transform relational data to hierarchical data, the wizard creates a hierarchical structure that reflects the relational input ports. You can use the Overview View to link relational ports to hierarchical ports.
To view the links between relational input to hierarchal output, use the Overview view. Select Input Mapping. The Ports panel appears in the Overview view.
The following image shows the Ports panel:
To the left of the Ports panel is the Transformation input area that contains the relational elements and groups. To the right is the Transformation output area that contains the hierarchical schema nodes.
You can create ports in the Transformation input area, and link relational elements to the schema nodes. You can also drag the pointer from a node in the schema to an empty field in the Transformation input area to create a port. When you connect a relational port to a schema node, the Developer tool shows a link between them.
