You might need to regenerate SLA data for work items from time to time. Escalation services execute JQL and regenerate SLA data for the work items that are returned by this query. On this page, you can set a time interval (how often the escalation service will be triggered) by cron expression.

On this page, you can create new escalation services, as well as edit and delete them.
