Default Change Type
The default Change Type applied to attribute columns on Dimensions derived by the Dimensional Accelerator.
| Option | Description |
|---|---|
CHG (Update) | Changes are applied in place — a Type 1 attribute |
HST (Track History) | History is kept for the column — a Type 2 attribute |
The value seeds the Change Type of the attribute columns when the Dimensional Accelerator derives a Dimension; individual columns can be changed afterwards in the column editor or through the accelerator's column actions.
When to Change This Setting
Set it to HST when new Dimensions should track history by default instead of updating in place.
