Custom fields are used globally across Jira, so you will need to have the Jira Administrator global permission to carry out management operations such as creation and configuration.

Jira maintains all the custom fields in a centralized location for easy management. Perform the following steps to access the custom field management page:

1. Log in as a Jira administrator user.
2. Browse to the Jira administration console.
3. Select the Issues tab and then the Custom fields option:

On the Custom fields page, all the existing custom fields will be listed. From here, you can see the names of all custom fields, their type, the context they belong to, and the screens they are displayed on. Note that some custom fields, such as Development and Epic Color, as shown in the previous screenshot, come with Jira itself, and will have the LOCKED label next to their names. These fields serve special purposes in Jira, so their configurations cannot be changed. User-added custom fields, such as Department, do not have this restriction and can be updated at any time.
