## What You Can Change

| Field | Editable after creation? |
| --- | --- |
| Transformation Type | Yes |
| Source Field(s) or SQL Expression | Yes |
| Target Type / Format (Cast) | Yes |
| Term Settings (Cleaned Entity Name) | Yes |
| Description | Yes |
| Owner (Editors only) | Yes |
| Additional Metadata | Yes |
| Name | No |
| Parent container | No |

The name is set at creation and shown as a read-only header in the Edit modal. If you need to rename the field, use the **Rename** action from the settings dropdown instead. The parent container is also fixed; to move a Computed Field to a different container, create a new one there and delete the old one.

> **Info: Permissions**
>
> Editing requires the **Editor** team permission on the parent datastore, or the **Author** team permission when you are the current owner. Reassigning ownership always requires **Editor**. See [Permissions](https://userguide.qualytics.io/fields/computed-fields/deep-dive/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.

> **Note: Editing re-registers the definition**
>
> Saving an edit re-registers the transformation on the container. Existing quality checks that reference the field are preserved. Saving also runs a quick profile of the container that computes values against the new transformation. Anomalies raised against the previous definition remain in the anomaly history for auditability.
