If you use a Hierarchy Processor transformation to convert hierarchical data to hierarchical data and you add multi-level arrays to the output, you must ensure that the data sources for the output group or fields do not conflict. A conflict occurs when you select an incoming array and one of its descendant arrays as data sources for the same output group or field.
If you have a data source conflict, the transformation remains invalid until you resolve the conflict. Additionally, you cannot configure joins, filters, order by fields, or group by fields until you resolve the conflict.
You add the following Input group to the Output group and preserve the incoming field:
If you select both Array1 and Array2 as data sources for the Output group, there is no way to determine which data source provides the data for Field1 and Field2. In this case,
displays a conflicting data sources error.
To resolve the conflict, remove one of the data sources from the Output group.
