# Delete assets that are missing from source

As a result of import or synchronization operations, assets that were present in your Collibra environment but are no longer available in the external system may have their status changed to **Missing from source** instead of being permanently deleted. After a review of those assets you may want to remove them from Collibra. You can use the **Delete missing assets** workflow to delete any assets from a selected domain that have the **Missing from source** status.

{% hint style="success" %}
Download the [**Delete missing assets**](https://cdn.collibra.com/developer/Delete%20missing%20assets-bar.zip) workflow.
{% endhint %}

{% hint style="success" %}
You can adjust the workflow to target any other status by updating the **statusId** process variable.
{% endhint %}

## Configuration

After you have uploaded the workflow to your environment, access the workflow configuration via <img src="https://2912049260-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F8DYDBo6jzvQ73H6CZj6k%2Fuploads%2Fgit-blob-75245abf5c50ddf56f1d2d727ccaacf757d11145%2Fcogwheel-large%402x.png?alt=media" alt="" data-size="line"> **Settings** → **Workflows** → **Definitions** → **Delete Missing Assets**.

The workflow is meant to run at the community level. You must change the scope of the workflow to apply to **Community**.

Additionally, you may want to change the description, the start label or to allow only specific roles to be able to start this workflow.

## Walk-through

After you have enabled the workflow, go to a community containing domains with assets that are missing from source. To start the workflow, click **Actions** → **Delete Missing Assets**.

You must select one or more domains from the current community and acknowledge that deleting those assets is an irreversible process before you can click the **Delete missing assets** button to permanently delete those assets.

Depending on the number of assets that have the **Missing from source** status, the workflow may take some time and computing resources to complete.
