= Trac Ticket Batch Modification =
[[TracGuideToc]]

From [TracQuery custom query] results Trac provides support for modifying a batch of tickets in one request.

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 in addition of replacing the entire list value. All list field controls accept multiple items (i.e. 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 in conjunction with more suitable actions like 'prepend', 'append' or search & replace ([http://trac-hacks.org/ticket/2415 th:#2415]) this could change in future Trac versions.
