Configuring data sources

Configuring data sources

You can configure a data source for the output group and for all array and struct fields in the output. A data source identifies the input group or incoming array that populates the primitive child fields for the output group or field.
If you select a field as a data source, you have access to the following objects:
  • All its primitive children
  • All its ancestors’ primitive children
  • Individual elements of its array children
  • Individual elements of its ancestors’ array children
You can configure multiple data sources for an output group or field. If you do this, you must configure a join condition to join the data.
You can configure filters to exclude certain records. You can also specify group by fields for aggregating the data and order by fields for sorting records.
The data sources for hierarchical output group and fields can vary based on the output data structure.
