Prerequisites

• Roles: admin, notification_admin, or itil (for viewing)
• Access: sysevent_email_action, sysevent_email_template, sys_script_email tables
• Knowledge: GlideRecord basics, email concepts, event registry
• Related Skills: Complete admin/workflow-creation for workflow-triggered notifications

Notification Architecture

Core Tables

sysevent_register (Event Registry)
    |
    +-- sysevent_email_action (Email Notifications)
            |
            +-- sysevent_email_template (Email Templates)
            +-- sys_script_email (Mail Scripts)
            +-- cmn_notif_message (Notification Messages)

Notification Types

Type	Trigger	Use Case
Event-based	System/custom events	Standard approach - decoupled, reusable
Direct	Record conditions	Quick setup - tightly coupled to conditions
Workflow	Workflow activity	Part of workflow orchestration
Script	GlideEmailOutbound	Programmatic - full control

Key Tables Reference

Table	Purpose
sysevent_email_action	Email notification definitions
sysevent_email_template	Email body templates
sysevent_register	Event definitions
sys_script_email	Mail scripts for recipients
sys_email	Email log (sent/failed)
cmn_notif_message	Notification message store
cmn_notif_device	User notification devices

Procedure

Step 1: Understand Event-Based vs Direct Notifications

Event-Based Notifications (Recommended):

• Triggered by events (e.g., incident.assigned, change.approval.rejected)
• Decoupled from business rules
• Can have multiple notifications per event
• Better for complex, reusable notification logic

Direct Notifications:

• Triggered directly by record conditions
• Simpler to set up
• Tightly coupled to specific conditions
• Good for one-off notifications

Step 2: Query Existing Events

Before creating notifications, understand available events.

Query Event Registry:

Tool: SN-Query-Table
Parameters:
  table_name: sysevent_register
  query: table=incident
  fields: sys_id,event_name,table,description,fired_by
  limit: 50

Common System Events:

Event	Table	Trigger
incident.assigned	incident	Incident assigned to user/group
incident.commented	incident	Comment added
incident.resolved	incident	Incident resolved
incident.reopened	incident	Incident reopened
change.approval.rejected	change_request	Change approval rejected
change.itil.approval.rejected	change_request	ITIL change rejected
sc_request.approved	sc_request	Request approved
sla.warning	task_sla	SLA warning threshold
sla.breached	task_sla	SLA breached
approval.inserted	sysapproval_approver	Approval record created
task.assigned	task	Task assigned

Step 3: Create Custom Event (Optional)

If no existing event matches your needs, create a custom event.

Create Event Registration:

Tool: SN-Create-Record
Parameters:
  table_name: sysevent_register
  data:
    event_name: "x_custom.incident.escalated"
    table: "incident"
    description: "Fired when incident is escalated to management"
    fired_by: "Business Rule: Incident Escalation"

Fire Event from Business Rule:

// In business rule script
if (current.escalation.changes() && current.escalation > 0) {
    gs.eventQueue('x_custom.incident.escalated', current, current.assigned_to, current.assignment_group);
}

Fire Event via Background Script:

Tool: SN-Execute-Background-Script
Parameters:
  script: |
    var inc = new GlideRecord('incident');
    inc.get('number', 'INC0010001');
    if (inc.isValidRecord()) {
        gs.eventQueue('x_custom.incident.escalated', inc, inc.assigned_to.toString(), inc.assignment_group.toString());
        gs.info('Event fired for: ' + inc.number);
    }
  description: "Fire custom escalation event for testing"

Step 4: Create Email Notification

Basic Event-Based Notification:

Tool: SN-Create-Record
Parameters:
  table_name: sysevent_email_action
  data:
    name: "Incident Escalation Alert"
    event_name: "x_custom.incident.escalated"
    sys_domain: "global"
    collection: "incident"
    active: true
    # Subject
    subject: "URGENT: Incident ${number} Escalated - ${short_description}"
    # Recipients
    send_to_event_creator: false
    recipient_users: [user_sys_id]  # Specific users
    recipient_groups: [group_sys_id]  # Groups
    send_to_event_parm_1: true  # gs.eventQueue parm1 (assigned_to)
    send_to_event_parm_2: true  # gs.eventQueue parm2 (assignment_group)
    # Content
    content_type: "text/html"
    message_html: |
      <html>
      <body>
      <h2>Incident Escalated</h2>
      <p>The following incident has been escalated and requires immediate attention:</p>
      <table border="1" cellpadding="5">
        <tr><td><b>Number:</b></td><td>${number}</td></tr>
        <tr><td><b>Priority:</b></td><td>${priority}</td></tr>
        <tr><td><b>Description:</b></td><td>${short_description}</td></tr>
        <tr><td><b>Assigned To:</b></td><td>${assigned_to}</td></tr>
        <tr><td><b>Assignment Group:</b></td><td>${assignment_group}</td></tr>
        <tr><td><b>Escalation Level:</b></td><td>${escalation}</td></tr>
      </table>
      <p><a href="${URI_REF}">View Incident</a></p>
      </body>
      </html>

Direct (Condition-Based) Notification:

Tool: SN-Create-Record
Parameters:
  table_name: sysevent_email_action

    action_insert: true
    action_update: false
    action_delete: false
    condition: "priority=1^state=1"  # P1, New state
    active: true
    subject: "P1 Incident Created: ${number}"
    send_to_event_parm_1: true
    content_type: "text/html"
    message_html: |
      <h2>Priority 1 Incident Created</h2>
      <p>A new Priority 1 incident requires immediate attention.</p>
      <p><b>Number:</b> ${number}</p>

Step 6: Create Mail Script for Dynamic Recipients

Mail scripts allow complex recipient logic beyond simple field references.

Create Mail Script:

Tool: SN-Create-Record
Parameters:
  table_name: sys_script_email
  data:
    name: "Get On-Call Manager"
    description: "Returns the on-call manager for the assignment group"
    script: |
      // Mail script to find on-call manager
      // 'current' is the record, 'email' is the GlideEmailOutbound object

      (function runMailScript(current, template, email, email_action, event) {

        // Get on-call rotation for assignment group
        var oncall = new GlideRecord('on_call_rotation');
        oncall.addQuery('group', current.assignment_group);
        oncall.addQuery('active', true);
        oncall.query();

        if (oncall.next()) {
          // Add on-call user as recipient
          var user = new GlideRecord('sys_user');
          user.get(oncall.user);
          if (user.isValidRecord() && user.email) {
            email.addAddress('to', user.email, user.name);
            gs.info('Mail script: Added recipient ' + user.email);
          }
        }

        // Optionally add escalation manager
        if (current.escalation > 1) {
          var manager = current.assignment_group.manager;
          if (manager && manager.email) {
            email.addAddress('cc', manager.email, manager.name);
          }
        }

      })(current, template, email, email_action, event);

Associate Mail Script with Notification:

Tool: SN-Update-Record
Parameters:
  table_name: sysevent_email_action

      (function runMailScript(current, template, email, email_action, event) {

        var MAX_LEVELS = 3;
        var userId = current.assigned_to.toString();

        for (var level = 0; level < MAX_LEVELS && userId; level++) {
          var user = new GlideRecord('sys_user');
          user.get(userId);

          if (user.isValidRecord() && user.manager) {
            var manager = new GlideRecord('sys_user');
            manager.get(user.manager);

            if (manager.isValidRecord() && manager.email) {
              email.addAddress('cc', manager.email, manager.name);
              userId = manager.sys_id.toString();
            } else {
              break;
            }
          } else {
            break;
          }
        }

      })(current, template, email, email_action, event);

${field_name.name}       - Reference field's name
${field_name.email}      - Reference field's email
${field_name.sys_id}     - Reference field's sys_id
${number}                - Incident number
${short_description}     - Short description
${priority}              - Priority display value
${state}                 - State display value

Special Variables:

${URI}                   - Record URI path only
${URI_REF}               - Full URL to record

    template.print('<span style="color: red; font-weight: bold;">CRITICAL</span>');
} else {
    template.print('<span>' + current.priority.getDisplayValue() + '</span>');
}

Iterating Over Related Records:

// Show related tasks in notification
template.print('<h3>Related Tasks:</h3>');
template.print('<ul>');

var tasks = new GlideRecord('sc_task');
tasks.addQuery('request_item', current.sys_id);
tasks.query();

while (tasks.next()) {

Best Practices

• Use Events: Prefer event-based over direct notifications for decoupling
• Template Reuse: Create templates for consistent formatting across notifications
• Test in Sub-Production: Always test notifications in dev/test first
• Monitor Email Queue: Regularly check sys_email for send-error records
• User Preferences: Respect user notification opt-out settings
• Business Hours: Consider time zones and business hours for non-critical alerts
• HTML + Plain Text: Provide both for maximum compatibility
• Avoid Spam: Use digest for high-frequency events
• Watermarks: Keep watermarks enabled to prevent duplicate notifications
• Document Events: Add descriptions to custom events for maintainability
