Add all descendants

Add all descendants

You can add all descendants when adding incoming struct and array fields to the output and the output format is relational. The "Add all descendants" option adds all children under the field to the output group, including all arrays and structs.
You can't map hierarchical data with arrays to the same output group when you select the "Add all descendants" option. If you add an incoming field that contains hierarchical data with arrays to the output group, the Hierarchy Processor transformation creates a separate output group for each array.

Example of adding all descendants

You want to add all incoming fields to relational output groups. The incoming fields contain the arrays Customer and Order.
Click
Add
next to the parent incoming field and select the
Add All Descendants
option. This action maps the fields in the Customer array to the first output group, and maps all fields in the Order array to the second output group.
The following image shows the input and output fields:
The list of incoming fields on the left includes a top-level struct: Customers, which contains an array: Customer. The next struct is Orders, which contains an array: Order. The output groups on the right, after applying Add All Descendants, are Customer and Order.
