Field groups

Field groups

You can configure field groups when you define the fields to be normalized. A field group defines a group of multiple-occuring fields in the source. The Normalizer transformation returns a row for each group occurrence instead of for each field occurrence.
Configure field groups when the source contains groups of multiple-occuring fields.
When a group of fields occurs multiple times in the source row, you can add child groups to configure the data hierarchy. The Normalizer transformation returns a row for each child group occurance multiplied by the parent group occurs value.
For example, a parent group that occurs four times contains a child group that occurs three times. The child group contains two fields that each occur once. The Normalizer transformation returns each field 12 times.
The following image shows the
Normalized Fields
tab with parent and child groups:
The Normalized Fields tab shows two group-level fields. The group "Quarter"
                        is at level 1 and occurs four times. The group "Category" is at level 2 and
                        occurs three times. The Category group contains the fields "sales" and
                        "returns" at level three. The fields each occur once. The tab also shows the
                        field "Year" as well as the generated GCID and GK fields at level 1.
The field level identifies the hierarchy of fields. Fields in the same group have the same level number and display sequentially below the group-level field. You can define up to ten levels in a group.
You can't configure field groups in advanced mode or SQL ELT mode.
