Data Preview Interface for Hierarchical Data

Data Preview Interface for Hierarchical Data

The data preview interface consists of Data Viewer view and hierarchical type panel. Preview data in a mapping based on the preview point that you choose.
The following image shows a mapping which has complex data types:
To view the hierarchical data after expressions have been evaluated, you use the Expression transformation as a preview point.
The following image shows the results of the data preview:
  1. Hierarchy keys
