# Specify a default field value

A default value populates a value in a field when a new record is created.

## Before you begin

Role required: personalize\_dictionary

## About this task

The default value populates the field on the blank form for a new record, and also subsequently when the new record is submitted if the field is empty. Default values can be specified as either a constant or generated through script.

## Procedure

1.  Right-click the field's label in the form and select **Configure Dictionary**.

2.  Enter the default value in the **Default value** field.

    To set a constant value, type it into the **Default value** text box field. To assign a default value using a more complex formula, use JavaScript to output a default value.

    **Note:** The default value should be the underlying value that would be present in the field, not the label. For example, in a choice list field, use the **value** of the choice as the default value, not the choice's name.

## Default field value examples

Review the following examples about specifying default field values.

### Constant default values

Here is an example that sets a default value for the **Priority** field.

### Javascript default values

To view out-of-box examples of JavaScript default values, navigate to **System Definition** > **Dictionary** and enter this filter: **\[Default value\] \[starts with\] \[javascript\]**. Open some of the records and view the default value javascript entries.

### Set a default value for assignment\_group

The following example sets a default value in a \[sys\_user\_group\] reference field by getting the ID from the name of a group.

```
javascript:GetIDValue('sys_user_group', 'Development');
```

### Set a default value for assigned\_to if user has the itil role

This example for the Task \[task\] table describes how to configure the default value for the \[assigned\_to\] user equal to the current user id if the user has a role of itil.

-   Column label: **Assigned to**
-   Column name: **\[assigned\_to\]**
-   Reference Specification section
    -   Reference: **User** \[sys\_user\]
    -   Reference qual condition: **\[Roles\] \[is\] \[itil\]**
-   Default value script:

    ```
    javascript:if (gs.hasRole("itil"))current.assigned_to = gs.getUserID();
    ```


### Set a default value for a duration field

To set a default value for a duration field, use the following in the **Default value** field of the duration field's dictionary entry:

```
javascript:current.duration_field.setDisplayValue('3 04:30:14');
```

Avoid hard-coding a particular date-time. If the system date-time format changes, the value becomes invalid. Instead, select the **Use dynamic default** check box and assign a dynamic filter option.
