Navigate to **All** > **Now experience framework** > **UI Builder**. 2. Open an experience to work in or create an experience by selecting **Create** > **Experience**. See [Configure how users interact with your applications in UI Builder](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/application-development/ui-builder/work-experiences.md) for more information on creating experiences. 3. Open or create a page. For more information, see [Manage UI Builder pages and page variants](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/application-development/ui-builder/work-pages.md). 4. If you do not have any components on your page, add a **Data set** component to your page. For more information, see [Add and configure components](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/application-development/ui-builder/add-components.md). 5. In the **Data and scripts** panel, select the **+** icon and then select **Data resource**. \[Omitted image "data-resource-open.png"\] Alt text: Arrow pointing to Data resource option. 6. Enter `evam` in the search field. 7.

Configure each EVAM data resource.
| EVAM data source | Description |
|---|---|
| EVAM Data Resource | Add an EVAM definition and other information about the data source. - Type: Composite. - When to evaluate: In the When to evaluate this data resource list, select **Immediately** to have the EVAM data resource instance evaluated on page load or select **Only when invoked** to use an event handler to evaluate the EVAM data resource. - EVAM definition: In the **EVAM Definition** field, add the EVAM definition record that is associated with the data resource. - Page cursor: In the **Page Cursor** field, add a page cursor for the EVAM definition. - Page size: In the **Page Size** field, add a size for the EVAM pagination. - Page number: In the **Page Number** field, add the page number for the EVAM pagination. - EVAM Filter Preference: In the **EVAM Filter Preference** field, add the sys\_ids for the EVAM data filter. To add an event handler for when that data fetch is initiated, succeeded, or failed, select **Events**. In the [Now Code Editor](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/application-development/ui-builder/ui-builder-glossary.md) section, which is next to the Configuration pane, preview the EVAM definition script. \[Omitted image "EVAM-Data-Resource-Sample.png"\] Alt text: EVAM Data Resource Configuration. |
