Defining hierarchical output with the Hierarchy Processor transformation

Defining hierarchical output with the Hierarchy Processor transformation

You can map the incoming fields to output fields to configure the output data structure for hierarchical output.
When the output data format is hierarchical, consider the following guidelines:
  • There is a specific order that you should follow when performing operations.
  • You can rename or delete output groups.
  • You can aggregate both the input and output data.
The following image shows the
Hierarchy Processor
 tab with relational input and hierarchical output:
The Hierarchy Processor tab appears with Output Format Hierarchical selected. The transformation contains the incoming groups and fields in the left panel and an output group and fields in the right panel. The Data Configuration icons, links to output fields, and links to expressions provide ways to define the data processing strategy.
  1. Output format. Select
    Hierarchical
     to construct a hierarchical schema for incoming fields.
  2. Input groups, incoming fields. Use these fields to map to the output fields.
  3. Output fields. Use these fields to create the complex output file.
  4. Add incoming field to output group. Use to add fields to the output group.
  5. Output field names. Click on a field name to modify the field name or data type.
  6. Data Configuration icons. Use to configure the output groups and fields.
  7. Expression. Click on an expression to view or customize the output field expression.
  8. Add or delete output field. Use to create or delete output fields.
You can resize the Incoming Fields or Output Fields panels to better see the information.
