When you add incoming struct and array fields to the output, you can choose to add all descendants. This option adds all children under the field to the output group, including all arrays and structs. You can select this option when the output is relational.
Hierarchical data with arrays cannot be mapped to the same output group when you select this option. If you add an incoming field that contains hierarchical data with arrays to the output group,
creates a separate output group for each array.
You want to add all fields in the Input field to relational output groups. The incoming fields contain the arrays Customer and Order.
Add the Input field to the output fields by selecting
Add All Descendants
The following image shows the transformation input and output:
maps the fields in the Customer array to the first output group. It maps all fields in the Order array to the second output group.
