# Assignment rules module

The Assignment rules module allows you to automatically set a value in the assigned\_to and assignment\_group fields when a set of conditions occurs.

You can modify and create assignment rules by navigating to **All** > **Routing and Assignment** > **Assignment Rule**. An assignment rule must also meet these additional criteria to run:

-   The task record has been created or updated. Assignment rules do not apply to unsaved changes on a form.
-   The task record must be unassigned. The record cannot have an existing value for either the assigned\_to or assignment\_group fields. Assignment rules cannot overwrite existing assignments \(including assignments set by a default value or a previously run assignment rule\).
-   The assignment rule is the first rule that matches the table and conditions. If more than one assignment rule matches the conditions, only the rule with the lowest order value runs.
