# Make a field dependent

A choice or reference field can be declared dependent on another field on the same table to limit the values available to select based on the value of the dependent field.

## Before you begin

Role required: personalize_dictionary or admin

## About this task

If a required dependency does not function as expected, as might happen if there is a
many-to-many relationship between the fields, consider using reference qualifiers to
accomplish the goal.  
Note:  
* Fields cannot be made dependent on derived fields.
* When you create a dependency between reference fields (similar to assignment group and assigned to), you must add <kbd class="ph userinput">_group</kbd> to the name of the field on which the other is dependent on to get the expected behavior. See [KB0998861: Dependent field does not work as expected on task "Assigned to" field](https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB0998861) for more information.

## Procedure

1. Navigate to a form that contains the field that you want to make dependent on another field.  
   For example, to configure a field in the Incident \[incident\] table, navigate to AllIncidentAll and select New.
2. Right-click the field label in the form and select ConfigureDictionary.
3. From the Dependent field tab, select Use dependent field and select the name of the field that this field will depend on.  
   Note:  
   For some field types, you may only need to enter the name of a field in the same table on which the field depends.
4. Select Update.

## Dependent field {#t_MakingAFieldDependent__example_oxj_433_gfc}

In the example below, the Subcategory field is made dependent upon the Category field. On an incident form, the value selected for the Category field determines which options appear for the Subcategory field.
