Create and Modify Scripted Fields
From January 2026, Atlassian has changed how custom fields are configured in Jira (see this article for details). New custom fields are no longer automatically linked to all field configuration schemes. Instead, you must associate custom fields with a field configuration scheme and add them to the relevant space screens. In addition, Field Configurations and Field Configuration Schemes are merging into a new Field Schemes option.
Impact on Scripted Fields:
When you create a new scripted field that uses custom fields and attempt to add it to a space, it will not appear unless it has first been associated with a field configuration scheme. To associate a scripted field with a space, navigate to Jira Settings > Field Configuration and select the Custom Field (Scripted Field). You can then associate the field with the appropriate field configuration scheme and add the field to the relevant space screen.
