= Trac Ticket Batch Modification =
[[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).

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. You will need to have JavaScript turned on for this to work.

== 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]).
