* **View** opens the Source Authority read-only.
* **Edit** opens the form so you can change any field except the code. Click **Submit** to save your changes. See [Add a Source Authority](/version/v2.0.0/configure/source-authorities/add-a-source-authority.md) for details of each field.
* **Delete** removes the Source Authority after you confirm by clicking **Delete**.

{% hint style="warning" %}
A Source Authority can't be deleted while a [Data Source](/version/v2.0.0/configure/data-sources.md) uses it. Change or delete those Data Sources first.
