[[TracGuideToc]]

Trac supports modifying a batch of tickets in one request from [TracQuery custom query] results. The Batch Modify functionality only appears on Query pages (/query), not Report pages (/report). You must have !JavaScript enabled in your browser.

To perform a batch modification, select the tickets you wish to modify and set the new field values using the section underneath the query results.

== List fields

The `Keywords` and `Cc` fields are treated as lists, where list items can be added and/or removed, as well as replacing the entire list value. All list field controls accept multiple items, such as multiple keywords or cc addresses.

== Excluded fields

Multi-line text fields are not supported, because no valid use-case has been presented for syncing them across several tickets. That restriction applies to the `Description` field as well as to any [TracTicketsCustomFields#AvailableFieldTypesandOptions custom field] of type 'textarea'. However, future versions of Trac could support batch modification of textareas in conjunction with more suitable actions like 'prepend', 'append' or 'search & replace' ([trac:#11197]).
