Before You Delete¶
Deleting a Computed Field is a hard delete. There is no archive step and no undo. Understand what goes with it before you confirm:
| What happens to... | Effect |
|---|---|
| The Computed Field definition | Removed permanently. |
| The derived output field | Removed permanently. |
| Quality checks that target the Computed Field | Removed together with the field. |
| Expected Schema checks that list the Computed Field | Kept. The field is removed from their list of expected fields. |
| Anomalies raised against the Computed Field | Removed together with the field. |
| Source fields the transformation reads | Not affected. They retain their status and configuration. |
Irreversible
Once a Computed Field is deleted, the definition and the derived value cannot be recovered. Copy the transformation first if you might need it again.
A Computed Field cannot be excluded on its own. For a Cast, Cleaned Entity Name, or Convert Formatted Numeric field, excluding its source field also excludes the output and keeps the definition for later restoration, but it stops monitoring the source field too. A Custom Expression declares no source fields, so exclusion never suppresses it. See Exclude a Field for the exclusion flow.
Permissions
Deleting requires the Editor team permission on the parent datastore, or the Author team permission when you are the current owner. See Permissions for the full matrix.
Steps¶
Step 1: Navigate to the Computed Field's detail page by clicking its name in the container's field listing.
Step 2: Click the settings icon in the top-right corner of the field page. A dropdown appears with the actions available for the field.
Step 3: Select Delete .
Step 4: A confirmation dialog appears listing what will be removed together with the field.
Step 5: Read the summary and click Delete to confirm. The field is removed immediately, together with its quality checks and anomalies.
Step 6: A success message confirms the deletion and the Computed Field no longer appears in the container's field listing.
