When you enable field-level auditing, your application tracks changes that users make to fields in the data model that your case contains. Users of your application can then check previous and current field values, the last user to change the values, and the time of their modification.

For relevant training materials, see the Tracking and auditing changes to data module and Auditing changes to the value of fields challenge on Pega Academy.

1. In the navigation pane of App Studio, click Case types, and then click the case type that you want to open.
2. In the case working area, click the Settings tab.
3. In the settings pane, click Auditing.
4. In the Auditing window, turn on the Enable field audit switch.
5. In the Fields column, select the checkboxes next to the fields that you want to enable for auditing.
   Note: Field-level auditing does not support data reference, page group, value group, and value list field types.

   Note: If an application tracks changes in an embedded data field and the scope of the changes is greater than 66%, the application recognizes the changes as delete an add actions, and displays relevant audit information.
6. If you want to enable fields in an embedded data field, click the name of the field, and then repeat step 5.
