Limitations
===========

Triggers are one way of automated actions. In addition, there are also
:doc:`scheduler </manage/scheduler>` and
:doc:`postmaster filter </channels/email/filters>` based automation. Make sure
to have a look at those, too. They can be more suitable, depending on your
use case.

Limitations of triggers:

- Triggers are executed when a ticket is updated via clicking the "Update"
  button. Changing a value without updating the ticket (e.g. setting a tag) will
  not execute the trigger.
- Triggers are always affecting the last article of a ticket. This means you
  can't run triggers based on older articles.
- Triggers always handle the current ticket attributes and the article
  (if applicable) that causes the trigger to fire. A related object context
  might not be available for performing changes.
