    Zurich

    Starting from the Zurich release, On-Call Scheduling uses subflows, not workflows. You must transition from workflows to subflows, because the workflows are considered as legacy workflows. For existing users in Zurich, your current workflows continue to be supported. However, for new users, the On-Call Scheduling plugin installations on Zurich and later instances only use subflows.

    Maintain, build, and modify your own custom on-call scheduling flows in Workflow Studio with subflows for new instances. The following subflows are available for configuration:

    Add custom on-call notification channels
    Increase the flexibility in communication by adding and configuring service providers as on-call notification channels. You must configure the communication channel by using the On-call communication channel configuration [on_call_comunication_channel_config] table. After you configure the channel, you can select the new channel. This feature is applicable only after the subflows are configured and used.
    Customize the on-call notification message and keywords
    Customize an on-call notification message and response keywords that are sent to the user and user groups as per your preferences. You can customize the message and keywords by using the On-call communication channel configuration [on_call_communication_channel_config] tables.
    Send the on-call escalation notifications when the configured record fields are modified
    Send the on-call escalation notifications when the configured record fields are modified. On-call trigger rules have the following enhancements:
    • Configure the changes to fields as a triggering condition to run trigger rules. For example, changes to the Priority field for an incident can be configured as a trigger condition.
    • Configure the group or team level trigger rules, or you can configure the global trigger rules that aren’t associated with a user group.
    • If the assignment group is auto-populated when an incident is created, you can still configure the on-call trigger rules to run and send the escalation notifications.

    Changes

    Between your current release family and Zurich, some changes were made to existing On-Call Scheduling features.

    Release Release notes

    Xanadu

    On-Call Scheduling new schedule engine
    The new 2024 schedule engine offers a more efficient and improved experience for managing your schedules and shifts. On-Call Scheduling supports an automatic upgrade to the new schedule engine.
    On-Call Scheduling new schedule engine
    The new schedule engine introduces the following enhancement:
    • Shift support to resolve gaps resulting from member placement.
    • Resolve daily rotation gaps, caused by adding or removing members, holiday schedules, or extra time.
    • Verifies user continuity based of the last on-call member from the previous schedule.
    • Improved performance by reducing the time required to add, remove, or move members.

    Email redirection behavior for links in major on-call schedule email notification
    In all major on-call schedule or shift email notifications, you can now decide where the links to an on-call schedule or shift record are redirected. Instead of an on-call schedule or shift record automatically opening in the classic UI16 interface in On-Call Scheduling, the record can be opened in SOW. The on-call schedule or shift record link in an email notification opens in SOW only if the following conditions are met:
    • The Redirect SOW Email notification (sow_email_notification_redirect) property is set to true.
    • The Redirect SOW Email notification for On-call scheduling (sow_email_notification_redirect.on_call) property is set to true.
    • You have the sn_sow_user role.

    The ITSM Notifications Redirection (com.snc.itsm.notifications_redirection) plugin is installed and activated automatically to support this behavior.

    Zurich

    Performance improvements in subflows for on-call notifications
    The following performance enhancements are available for on-call notifications when subflows are used:
    • On-call notifications are sent to multiple channels such as SMS or email simultaneously instead of sending it sequentially.
    • When the com.snc.on_call_rotation.new_trigger_engine property is set to true, the on-call subflows are processed via the Flow runner queue. The on-call subflows that are marked as High priority are processed faster via a Flow runner queue especially when multiple events are triggered at the same time and are in the process queue.
    • Reminder notifications are also sent to users when the instance is upgrading.
    Enhanced on-call trigger rules to support subflows
    The on-call trigger rules form is enhanced to trigger a subflow when the trigger rule is executed. You can enable and select a specific subflow for a trigger rule.
