Configuring hierarchical output group and fields

Uou can create and modify the output group and output fields for hierarchical output.

After you add incoming fields to an output group, you can select an output field name to modify the fields. You can also add and define output fields manually.

Name and Type

The following table describes the properties for hierarchical output fields:

Property	Description
Child Of	The parent field or group that this field belongs to. The name structure describes the group, parent fields, and struct name. For example: OUTGROUP.Grandparent.Parent.struct_name
Name	The name of the current output group or field.
Type	The data type of the current field. For hierarchical output, you can choose either a primitive or complex data type.
Precision	The total number of significant digits in the field.
Scale	The number of digits to the right of the decimal point.
Array Element Type	The data type of the current array element.
Array Element Precision	The precision for the current array element. Used when creating the target data.
Array Element Scale	The scale for the current array element. Used when creating the target data.
Struct Name	The struct name for the current struct field.
Element Struct Name	The element struct name for the current array of structs field.
Description	Optional description of the field and its usage.

The output field properties that appear depend on the data type.

Aggregate Options

All output fields except for parent fields have aggregation options that you can set. The following table describes the aggregate options:

Property	Description
Use this field to aggregate values in an output field array.	Select this property to aggregate output data into the current field.
Output Field	If you are aggregating, specify the sibling array with fields to aggregate. The array must be a child of the current output field or group.
