Output Relational Ports and the Overview View
To convert hierarchical data to relational output in the Hierarchical to Relational transformation, the wizard generates links between hierarchical nodes to relational ports. Use the Overview view to view the links between relational ports to hierarchical ports. You can also create groups of output ports by linking nodes from the hierarchical output to groups of ports.
To view the mapping for relational groups, use the Overview view. Select Output Mapping. The Ports panel appears in the Overview view.
The following image shows the Ports panel:
The Transformation input area, which shows the hierarchical schema, is to the left. The Transformation output area, which shows the relational output ports, is to the right.
You can define relational output ports in the Transformation output area and link nodes from the schema to the ports. You can also drag the pointer from a node in the schema to an empty field in the Transformation output area to create a port. When you drag a node from the output schema to a port, the Developer tool shows a link between them.
