Defining flattened output with the Hierarchy Processor transformation

Defining flattened output with the Hierarchy Processor transformation

Use the
Hierarchy Processor
 tab to map incoming fields to output fields. The flattened output option allows you to create denormalized output.
The following image shows the
Hierarchy Processor
 tab with hierarchical input and flattened output:
The Hierarchy Processor tab appears with Output Format Flattened selected. The transformation contains selectable incoming fields in the left panel and an output group and fields in the right panel. Links to output fields provide ways to modify output fields. Field expressions are also visible in the left panel.
  1. Output format. Select
    Flattened
     to convert hierarchical input into denormalized output.
  2. Incoming fields. View the incoming data schema and field types.
  3. Output fields. View the output fields as you create the output file.
  4. Configure the output. Select incoming fields to build the flattened output file schema.
  5. Output field names. Click on a field name to modify the field name.
  6. Expression. View the field expressions to determine the input to output field mappings.
  7. Delete. Use to delete output fields.
Use the maximize icon and resize the Incoming Fields panel or Output Fields panel to see the information you need.
To define a Hierarchy Processor transformation with flattened output, perform the following tasks:
  1. Select the
    Flattened
     output format.
  2. Configure the transformation output by selecting incoming fields to add to the output.
  3. Optional. Rename output fields.
  4. Optional. Delete output fields.
