Defining a Hierarchy Processor transformation

To define a Hierarchy Processor transformation, use the Hierarchy Processor tab to map incoming fields to output fields, configure the output data structure, and optionally generate keys for relational output.
The following image shows the Hierarchy Processor tab with relational input and hierarchical output:
The Hierarchy Processor tab of the Hierarchy Processor transformation contains the source input groups and their incoming fields. The tab also contains the target output group and its output fields. The Data Configuration icons and links to output field expressions provide ways to define the data processing strategy.
  1. 1. Input groups, incoming fields. Use these fields to map to the output fields.
  2. 2. Output group, output fields. Use these fields to create the complex output file.
  3. 3. Data Configuration icons, field expressions. Use to configure the output fields.
  4. 4. Output data format. Use this to specify hierarchical or relational output data format.
  5. 5. Add incoming field to output group. Use to add fields to the output group.
  6. 6. Add output field. Use to create output fields.
Tip: 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:
  1. 1. Configure the transformation output by adding incoming fields to the output or by manually adding fields to the output.
  2. 2. If the output is relational, optionally generate keys for the input group to define relationships between output groups.
  3. 3. Configure the output data.
  4. Configure data sources and optionally add filters. If the output is hierarchical, you can also join data sources if required, and optionally add group by and order by fields.
