## 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. |

> **Warning: 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](https://userguide.qualytics.io/fields/field-status/managing-field-status/exclude-a-field/#computed-fields-and-exclusion) for the exclusion flow.

> **Info: Permissions**
>
> Deleting requires the **Editor** team permission on the parent datastore, or the **Author** team permission when you are the current owner. See [Permissions](https://userguide.qualytics.io/fields/computed-fields/deep-dive/permissions/) for the full matrix.
