# Add fields to table-to-table relationships

You can enhance relationships between tables by adding additional fields, like [lookup](/v1/docs/creating-lookup-fields) and [summary](/v1/docs/create-a-summary-field) fields. These fields can help users by showing them more information or letting them move back and forth between tables quickly and easily. Read [About table-to-table relationships](/v1/docs/what-are-table-to-table-relationships) to learn more about these field types. You can add one of these fields at any time.

To add fields to a relationship:

1. Open the app that contains the relationship you want to enhance with additional fields.

If you created a relationship between tables in two different apps (a cross-app relationship), open the application that contains the child table.
2. Open the table.
3. Select **Settings**, then select **Table-to-table relationships**.
4. Select the relationship that you want to edit. The relationship properties appear:

5. Add the fields:
  - To add a [Lookup](/v1/docs/what-are-table-to-table-relationships#fields-used-with-relationships) field, select **Add Lookup Fields** at the bottom of the **Child Table**. A **New Lookup Fields** page appears. For more details, see [Creating lookup fields](/v1/docs/creating-lookup-fields).
  - To add a [Summary](/v1/docs/create-a-summary-field) field, select **Add Summary Field** at the bottom of the **Parent Table**. A **New Summary Field** page appears. For more details, see [Creating summary fields.](/v1/docs/create-a-summary-field)
  - If your parent table doesn't already have a [Report Link](/v1/docs/what-are-table-to-table-relationships#fields-used-with-relationships) field, select **Create Report Link**. The report link field is automatically added.
  - If your parent table doesn't already have an "Add" button, which is called a [URL (formula)](/v1/docs/what-are-table-to-table-relationships#fields-used-with-relationships) field, select **Create "Add *Record*."** The URL (formula) field is automatically added.
6. When you have finished adding fields, select **Done** in the upper right to close the relationship properties.
