Add reference fields to a table using the same method as for any other field.

## Before you begin

Role required: personalize_form

## About this task

The related table also appears in the Available Tables list for future form customizations.

## Procedure

1. Open the desired form.
2. Right-click the header and select ConfigureForm Layout.
3. Use [dot-walking](https://www.servicenow.com/docs/access?context=c_DotWalking&version=xanadu&pubname=xanadu-platform-user-interface&ft:locale=en-US) to locate and select the field in the referenced table that you want to add.  
   It appears as Table name.Field. For example, the caller's email address appears as Caller.Email.
4. Click Save.

* **[Enable dynamic creation for reference fields](https://servicenow-prod.fluidtopics.net/5BBelP6aXrSdM7tvEKewaQ)**   
  When dynamic creation is enabled, entering a nonexistent value in a reference field creates a new record on the referenced table instead of returning an error.
* **[Configure cascade delete rules](https://servicenow-prod.fluidtopics.net/QDhlivHKsWanS1uCsoQR1Q)**   
  When a record is deleted, there are different options for how the deletion will affect records that reference the deleted record. You can configure what happens to records that reference a record when that record is deleted.
* **[Define the reference key](https://servicenow-prod.fluidtopics.net/RPFFpbJ6AMAkeO0BqsgNRg)**   
  By default, reference fields store the sys_id of the record in the database.
* **[Display a reference field as a choice list](https://servicenow-prod.fluidtopics.net/ruCjBp6R0fdyBVWa7fm6eQ)**   
  You can display a reference field as a choice list instead of opening a lookup window.
