# Mass edit entities

You can update the fields in multiple entities based on the values from another entity using the [**Copy from entity**](https://doc.sitecore.com/ch/en/users/content-hub/operations.html#UUID-4a7c0245-92d1-e55c-9460-cd7b2154f93f_section-idm273522663289272 "Copy from entity") operation. For each field, you can specify whether the mass edit replaces the existing value, appends new values, or leaves the existing value unchanged.

> [!warning]
> If the mass edit source contains a one-to-one relation, the mass edit job will fail for all the entities except the first one in the list, because a one-to-one relation cannot apply to more than one entity.

To mass edit entities:

1. On the menu bar, click the page for the entities you want to mass edit, for example **Assets**.
2. On the page, select the entities you want to edit.
3. Click **Actions** :mdiDotsHorizontal: > :mdiPencilOutline: **Edit**.
4. To copy metadata from an existing entity, click :mdiFileMultipleOutline: **Copy from entity**.
5. In the **Copy from entity** dialog, click the entity from which you want to copy metadata, and click **Done**.
6. Modify field values as required.
7. For each field, from the list next to it, select one of the following actions:
    - **None** - does not modify the value or change the property of the field.
    - **Replace** - overwrites the current value of the field.
    - **Append** - adds information to a field, or adds taxonomy items to a list of related items.
    - **Clear** - removes all items from a relation or removes the current value of a field.

    Which actions are available depends on the property type and how [mass edits are configured](https://doc.sitecore.com/ch/en/users/content-hub/settings.html "Settings").

8. Click **Apply**.

> [!note]
> Applying a mass edit creates a mass edit job. You can follow the progress of the job on your [**Background processes**](https://doc.sitecore.com/ch/en/users/content-hub/view-background-process-logs.html "View background process logs") page.
