Processing flattened output

The Hierarchy Processor transformation can convert a hierarchical input group to a flattened denormalized output group.

For example, you have a shop maintenance file that contains customer and vehicle information for all your customers. You want to denormalize the vehicle maintenance data and exclude personal information about the customers.
