The output group and all array and struct fields in the output require a data source. When you add an input group or incoming field to the output, the Hierarchy Processor transformation usually sets a data source for you. You can manually add or edit a data source.

Click the
Data Sources
icon for the output group.
Examine if there is already a data source configured for the output group. If it requires any changes, continue with these steps, otherwise you can exit the dialog box.
Click the
Add Data Source
icon to add a new data source.
Click the ellipsis icon to select the input group or array to use as a data source.
Validate the configuration.
Click
Save

Click the trash icon to remove any incorrect or unneeded data source.
To configure a data source for struct or array fields:
Click the
Data Sources
icon for the output group.
Examine if there is already a data source configured for the struct or array. If it requires any changes, continue with these steps, otherwise you can exit the dialog box.
Select the type of data source to use:
Inherit parent's data sources: Use the same data sources as the parent for the struct or array.
Use input group or incoming fields: Select an input group or incoming field to use as a data source.
