UI Actions

Overview

This skill covers creating and configuring UI Actions in ServiceNow:

• Form buttons (header/footer) and form context menu items
• List buttons, list context menu, and list choice actions
• Client-side scripts, server-side scripts, and combined execution
• Visibility conditions and role-based security
• Common patterns: Approve, Reject, Clone, Escalate, etc.
• Testing and debugging UI Actions

When to use: When you need to add custom buttons or menu items to forms and lists that execute client-side or server-side logic.

Who should use this: Developers and administrators who need to extend ServiceNow forms and lists with custom functionality.

Prerequisites

• Roles: admin, personalize (for basic UI actions), or specific application roles
• Access: sys_ui_action table, related tables for testing
• Knowledge: JavaScript, GlideRecord API, client-side g_form API
• Related Skills: admin/script-execution for server-side patterns

    name: "Escalate to Management"
    table: incident
    action_name: escalate_to_management
    order: 100
    active: true
    form_button: true
    client: false
    script: |
      // Server-side script
      current.escalation = 1;
      current.priority = 1;
      current.work_notes = "Escalated to management by " + gs.getUserDisplayName();
      current.update();
      action.setRedirectURL(current);
    comments: "Escalates incident to management with P1 priority"

Result: Returns sys_id of created UI action.

Step 2.2: Form Button with Client Script

Create a button with client-side confirmation:

    form_button: true
    client: true
    onclick: |
      // Client-side script
      var closeCode = g_form.getValue('close_code');
      var closeNotes = g_form.getValue('close_notes');

      // Validate required fields
      if (!closeCode) {
        g_form.showFieldMsg('close_code', 'Close code is required', 'error');
        return false;  // Prevent submission
      }

      if (!closeNotes) {
        g_form.showFieldMsg('close_notes', 'Close notes are required', 'error');
        return false;
      }

      // Confirm with user
      if (!confirm('Are you sure you want to close this incident?')) {
        return false;
      }

      // Submit the form
      gsftSubmit(null, g_form.getFormElement(), 'close_incident');
    script: |
      // Server-side script (runs after form submit)
      current.state = 7;  // Closed
      current.closed_at = new GlideDateTime();
      current.closed_by = gs.getUserID();
      current.update();
      action.setRedirectURL(current);
    comments: "Closes incident with validation and confirmation"

      if (!checked) {
        alert('Please select at least one record');
        return false;
      }

      // Redirect to export with selected sys_ids

      var list = GlideList2.get(g_form.getTableName());
      var checked = list.getChecked();

      if (!checked) {
        alert('Please select at least one incident to close');
        return false;
      }

      var count = checked.split(',').length;
      if (!confirm('Close ' + count + ' selected incident(s)?')) {
        return false;
      }

      // Submit to server
      gsftSubmit(null, g_form.getFormElement(), 'bulk_close');
    script: |
      // Server-side - process all checked records
      var sysIds = RP.getParameterValue('sysparm_checked_items');
      if (sysIds) {
        var ids = sysIds.split(',');
        for (var i = 0; i < ids.length; i++) {
          var gr = new GlideRecord('incident');
          if (gr.get(ids[i])) {
            gr.state = 7;  // Closed
            gr.close_code = 'Solved (Permanently)';
            gr.close_notes = 'Bulk closed by ' + gs.getUserDisplayName();
            gr.update();
          }
        }
      }
    comments: "Closes all selected incidents in bulk"

Phase 4: Context Menu (Form Right-Click)

Step 4.1: Form Context Menu Item

Add item to form right-click menu:

Tool: SN-Create-Record
Parameters:
  table_name: sys_ui_action
  data:
    name: "View Audit History"
    table: incident
    action_name: view_audit_history
    order: 500
    active: true
    form_link: true
    client: true
    onclick: |
      // Open audit history in new window
      var sysId = g_form.getUniqueValue();
      var tableName = g_form.getTableName();
      var url = 'sys_audit_list.do?sysparm_query=tablename=' + tableName +
                '^documentkey=' + sysId + '&sysparm_view=';
      window.open(url, '_blank');
    comments: "Opens audit history for current record in new tab"

Step 4.2: Form Link with Server Script

Context menu that runs server-side:

Tool: SN-Create-Record
Parameters:
  table_name: sys_ui_action
  data:
    name: "Create Child Incident"
    table: incident
    action_name: create_child_incident
    order: 600
    active: true
    form_link: true
    client: false
    script: |
      // Create child incident
      var child = new GlideRecord('incident');
      child.initialize();
      child.parent_incident = current.sys_id;
      child.short_description = 'Child of: ' + current.short_description;
      child.description = 'Child incident created from ' + current.number;
      child.caller_id = current.caller_id;
      child.category = current.category;
      child.subcategory = current.subcategory;
      child.priority = current.priority;
      var childId = child.insert();

      // Redirect to new child incident
      action.setRedirectURL(child);
    comments: "Creates a child incident linked to current record"

Phase 5: Conditions for Visibility

Step 5.1: Simple Field Conditions

Show button only for specific states:

Tool: SN-Create-Record
Parameters:
  table_name: sys_ui_action
  data:
    name: "Reopen Incident"
    table: incident
    action_name: reopen_incident
    order: 100
    active: true
    form_button: true
    condition: "current.state == 7"
    script: |
      // Reopen logic
      current.state = 2;  // In Progress
      current.work_notes = "Reopened by " + gs.getUserDisplayName();
      current.update();
      action.setRedirectURL(current);
    comments: "Visible only when incident is Closed (state=7)"

Common Condition Patterns:

| Condition | Meaning | |-----------|---------| | current.state == 1 | State equals New | | current.active == true | Record is active | | current.assigned_to == gs.getUserID() | Assigned to current user | | current.assignment_group.manager == gs.getUserID() | Current user is group manager | | current.isNewRecord() | New record (not saved yet) | | !current.isNewRecord() | Existing record only | | current.priority <= 2 | Priority is 1 or 2 | | current.caller_id.vip == true | Caller is VIP |

Step 5.2: Role-Based Conditions

Show button only for specific roles:

Tool: SN-Create-Record
Parameters:
  table_name: sys_ui_action
  data:
    name: "Override SLA"
    table: incident
    action_name: override_sla
    order: 100
    active: true
    form_button: true
    condition: "gs.hasRole('incident_manager') || gs.hasRole('admin')"
    script: |
      // SLA override logic
      current.sla_due = '';
      current.work_notes = "SLA overridden by manager";
      current.update();
    comments: "Visible only to incident managers and admins"

Step 5.3: Complex Conditions

Multiple conditions combined:

Tool: SN-Create-Record
Parameters:
  table_name: sys_ui_action
  data:
    name: "Emergency Escalation"
    table: incident
    action_name: emergency_escalation
    order: 50
    active: true
    form_button: true
    condition: |
      // Only show for P1/P2 active incidents assigned to current user's group
      current.state != 6 && current.state != 7 &&
      current.priority <= 2 &&
      current.assignment_group.getDisplayValue() != '' &&
      gs.getUser().isMemberOf(current.assignment_group)
    script: |
      // Emergency escalation logic
      current.escalation = 3;
      current.work_notes = "[EMERGENCY ESCALATION] " + gs.getUserDisplayName();
      current.update();
    comments: "Emergency escalation for P1/P2 incidents in user's group"

Step 5.4: UI Action Visibility Best Practices

Tool: SN-Create-Record
Parameters:
  table_name: sys_ui_action
  data:
    name: "Approve Request"
    table: sc_req_item
    action_name: approve_request
    order: 100
    active: true
    form_button: true
    condition: |
      // Best practice: Check multiple conditions
      var canApprove = false;

      // 1. Check record state
      if (current.approval == 'requested') {
        // 2. Check if user is an approver
        var approver = new GlideRecord('sysapproval_approver');
        approver.addQuery('sysapproval', current.sys_id);
        approver.addQuery('approver', gs.getUserID());
        approver.addQuery('state', 'requested');
        approver.query();

        if (approver.next()) {
          canApprove = true;
        }

        // 3. Or check if user has override role
        if (gs.hasRole('approval_admin')) {
          canApprove = true;
        }
      }

      canApprove;
    script: |
      // Approval logic
    comments: "Visible only when user can approve this request"

Phase 6: Client-Side vs Server-Side Scripts

Step 6.1: Client-Side Only (No Submit)

Action that only runs client-side:

Tool: SN-Create-Record
Parameters:
  table_name: sys_ui_action
  data:
    name: "Copy to Clipboard"
    table: incident
    action_name: copy_to_clipboard
    order: 100
    active: true
    form_button: true
    client: true
    onclick: |
      // Pure client-side - no server round trip
      var number = g_form.getValue('number');
      var shortDesc = g_form.getValue('short_description');
      var text = number + ': ' + shortDesc;

      // Copy to clipboard (modern browsers)
      navigator.clipboard.writeText(text).then(function() {
        g_form.addInfoMessage('Copied to clipboard: ' + text);
      }).catch(function(err) {
        alert('Failed to copy: ' + err);
      });

      // Return false to prevent form submission
      return false;
    script: ""
    comments: "Copies incident number and description to clipboard"

Step 6.2: Server-Side Only

Action that only runs server-side:

Tool: SN-Create-Record
Parameters:
  table_name: sys_ui_action
  data:
    name: "Recalculate Priority"
    table: incident
    action_name: recalculate_priority
    order: 100
    active: true
    form_button: true
    client: false
    script: |
      // Server-side only
      var calculator = new PriorityCalculator();
      var newPriority = calculator.calculate(current.impact, current.urgency);

      current.priority = newPriority;
      current.work_notes = "Priority recalculated to " + newPriority;
      current.update();

      action.setRedirectURL(current);
    comments: "Recalculates priority based on impact and urgency matrix"

Step 6.3: Combined Client and Server

Client validates/confirms, then server executes:

Tool: SN-Create-Record
Parameters:
  table_name: sys_ui_action
  data:
    name: "Transfer to Team"
    table: incident
    action_name: transfer_to_team
    order: 100
    active: true
    form_button: true
    client: true
    onclick: |
      // Client-side validation and data collection
      var group = g_form.getValue('assignment_group');
      if (!group) {
        g_form.showFieldMsg('assignment_group', 'Please select a group first', 'error');
        return false;
      }

      var reason = prompt('Enter transfer reason (required):');
      if (!reason || reason.trim() === '') {
        alert('Transfer reason is required');
        return false;
      }

      // Store reason in a hidden field or use sysparm
      g_form.setValue('work_notes', 'Transfer Reason: ' + reason);

      // Submit to server
      gsftSubmit(null, g_form.getFormElement(), 'transfer_to_team');
    script: |
      // Server-side execution
      var targetGroup = current.assignment_group.getDisplayValue();

      // Clear individual assignee
      current.assigned_to = '';

      // Add transfer audit trail
      current.work_notes = 'Transferred to ' + targetGroup + '\n' +
                           'Transferred by: ' + gs.getUserDisplayName();
      current.update();

      gs.addInfoMessage('Incident transferred to ' + targetGroup);
      action.setRedirectURL(current);
    comments: "Transfers incident with reason capture"

Phase 7: Using g_form in UI Actions

Step 7.1: Common g_form Methods

Reading Field Values:

// In onclick script
var value = g_form.getValue('field_name');
var display = g_form.getDisplayBox('field_name').value;
var reference = g_form.getReference('caller_id', function(ref) {
  // Async callback for reference fields
  alert('Caller name: ' + ref.name);
});

Setting Field Values:

// In onclick script
g_form.setValue('priority', '1');
g_form.setValue('work_notes', 'Updated via UI Action');
g_form.setDisplay('field_name', true);  // Show field
g_form.setMandatory('field_name', true);  // Make mandatory
g_form.setReadOnly('field_name', true);  // Make read-only

User Feedback:

// Messages
g_form.addInfoMessage('Operation completed successfully');
g_form.addWarningMessage('Please review the changes');
g_form.addErrorMessage('An error occurred');
g_form.showFieldMsg('field_name', 'Message text', 'info|warning|error');

// Clear messages
g_form.clearMessages();
g_form.hideFieldMsg('field_name');

Step 7.2: Complete Client Script Example

Tool: SN-Create-Record
Parameters:
  table_name: sys_ui_action
  data:
    name: "Validate and Submit"
    table: incident
    action_name: validate_submit
    order: 100
    active: true
    form_button: true
    client: true
    onclick: |
      function validateAndSubmit() {
        // Clear previous messages
        g_form.clearMessages();

        var valid = true;
        var errors = [];

        // Validate short description
        var shortDesc = g_form.getValue('short_description');
        if (!shortDesc || shortDesc.length < 10) {
          g_form.showFieldMsg('short_description', 'Must be at least 10 characters', 'error');
          valid = false;
          errors.push('Short description');
        }

        // Validate caller
        var caller = g_form.getValue('caller_id');
        if (!caller) {
          g_form.showFieldMsg('caller_id', 'Caller is required', 'error');
          valid = false;
          errors.push('Caller');
        }

        // Validate category
        var category = g_form.getValue('category');
        if (!category) {
          g_form.showFieldMsg('category', 'Category is required', 'error');
          valid = false;
          errors.push('Category');
        }

        // Check P1 requirements
        var priority = g_form.getValue('priority');
        if (priority == '1') {
          var businessImpact = g_form.getValue('business_impact');
          if (!businessImpact) {
            g_form.showFieldMsg('business_impact', 'Required for P1 incidents', 'error');
            valid = false;
            errors.push('Business Impact');
          }
        }

          return false;
        }

        // Confirmation
        if (confirm('Submit this incident?')) {
          gsftSubmit(null, g_form.getFormElement(), 'validate_submit');
          return true;
        }

        return false;
      }

      validateAndSubmit();
    script: |
      current.update();
      gs.addInfoMessage('Incident saved successfully');
      action.setRedirectURL(current);
    comments: "Validates required fields before submission"

Phase 8: Redirecting After Action

Step 8.1: Redirect Methods

Redirect to Same Record:

// Server-side script
action.setRedirectURL(current);

Redirect to Different Record:

// Server-side script
var newRecord = new GlideRecord('incident');
newRecord.get('some_sys_id');
action.setRedirectURL(newRecord);

Redirect to List:

// Server-side script
action.setRedirectURL('incident_list.do?sysparm_query=active=true');

Redirect to Specific URL:

// Server-side script
action.setRedirectURL('/nav_to.do?uri=incident.do?sys_id=' + current.sys_id);

Prevent Redirect (Stay on Form):

// Server-side script
current.update();
action.setRedirectURL(current);  // Refresh current record

Redirect to Previous Page:

// Client-side onclick
// After server processing, redirect back
history.back();
return false;

Step 8.2: Common Redirect Patterns

Clone and Redirect to New:

Tool: SN-Create-Record
Parameters:
  table_name: sys_ui_action
  data:
    name: "Clone Incident"
    table: incident
    action_name: clone_incident
    order: 100
    active: true
    form_button: true
    condition: "!current.isNewRecord()"
    client: false
    script: |
      // Clone the incident
      var clone = new GlideRecord('incident');
      clone.initialize();

      // Copy fields
      clone.short_description = 'CLONE: ' + current.short_description;
      clone.description = current.description;
      clone.caller_id = current.caller_id;
      clone.category = current.category;
      clone.subcategory = current.subcategory;
      clone.priority = current.priority;
      clone.impact = current.impact;
      clone.urgency = current.urgency;

      // Reference original
      clone.work_notes = 'Cloned from ' + current.number;

      var cloneId = clone.insert();

      // Redirect to new cloned record
      action.setRedirectURL(clone);
    comments: "Creates a copy of the current incident"

Save and Return to List:

Tool: SN-Create-Record
Parameters:
  table_name: sys_ui_action
  data:
    name: "Save and Return to List"
    table: incident
    action_name: save_return_list
    order: 100
    active: true
    form_button: true
    client: false
    script: |
      current.update();
      action.setRedirectURL('incident_list.do');
    comments: "Saves current record and returns to incident list"

Phase 9: Action Security

Step 9.1: Role-Based Access

Restrict to Specific Roles (Using Condition):

Tool: SN-Create-Record
Parameters:
  table_name: sys_ui_action
  data:
    name: "Delete Incident"
    table: incident
    action_name: delete_incident
    order: 900
    active: true
    form_button: true
    condition: "gs.hasRole('incident_admin')"
    client: true
    onclick: |
      if (!confirm('Are you sure you want to DELETE this incident? This cannot be undone.')) {
        return false;
      }

      if (!confirm('FINAL WARNING: This will permanently delete ' + g_form.getValue('number'))) {
        return false;
      }

      gsftSubmit(null, g_form.getFormElement(), 'delete_incident');
    script: |
      var number = current.number;
      current.deleteRecord();
      gs.addInfoMessage('Incident ' + number + ' has been deleted');
      action.setRedirectURL('incident_list.do');
    comments: "Permanently deletes incident - restricted to incident_admin"

Step 9.2: Create ACL for UI Action

Create explicit ACL protection:

Tool: SN-Create-Record
Parameters:
  table_name: sys_security_acl
  data:
    name: "incident.delete_incident"
    type: ui_action
    operation: execute
    active: true
    admin_overrides: false
    advanced: false
    script: "gs.hasRole('incident_admin')"
    description: "ACL for delete incident UI action"

Step 9.3: Security Best Practices

1. Always validate on server-side: Client-side checks can be bypassed
2. Use conditions AND ACLs: Defense in depth
3. Log sensitive actions: Create audit trail
4. Limit destructive actions: Require confirmation and restrict roles

Complete Secure Action Example:

Tool: SN-Create-Record
Parameters:
  table_name: sys_ui_action
  data:
    name: "Override Approval"
    table: sc_req_item
    action_name: override_approval
    order: 100
    active: true
    form_button: true
    condition: |
      // Check role and record state
      gs.hasRole('approval_admin') &&
      current.approval == 'requested' &&
      !current.isNewRecord()
    client: true
    onclick: |
      // Client-side confirmation
      var reason = prompt('Enter override reason (required for audit):');
      if (!reason || reason.trim().length < 10) {
        alert('A detailed reason (min 10 chars) is required for approval override');
        return false;
      }

      if (!confirm('Override approval for ' + g_form.getValue('number') + '?')) {
        return false;
      }

      // Store reason
      g_form.setValue('work_notes', 'APPROVAL OVERRIDE REASON: ' + reason);
      gsftSubmit(null, g_form.getFormElement(), 'override_approval');
    script: |
      // Server-side validation (defense in depth)
      if (!gs.hasRole('approval_admin')) {
        gs.addErrorMessage('Unauthorized: approval_admin role required');
        action.setRedirectURL(current);
        return;
      }

      // Process override
      current.approval = 'approved';
      current.work_notes = 'APPROVAL OVERRIDE\n' +
                           'Overridden by: ' + gs.getUserDisplayName() + '\n' +
                           'Date: ' + new GlideDateTime().getDisplayValue();
      current.update();

      // Audit log
      gs.log('Approval override on ' + current.number + ' by ' + gs.getUserName(), 'ApprovalOverride');

      gs.addInfoMessage('Approval overridden successfully');
      action.setRedirectURL(current);
    comments: "Override approval with audit trail - approval_admin only"

    client: true
    onclick: |
      var currentLevel = parseInt(g_form.getValue('escalation')) || 0;
      var levels = ['Normal', 'Moderate', 'High', 'Overdue'];
      var nextLevel = levels[currentLevel + 1] || 'Maximum';

      if (!confirm('Escalate to ' + nextLevel + ' level?')) {
        return false;
      }
      gsftSubmit(null, g_form.getFormElement(), 'escalate_incident');
    script: |
      var oldLevel = current.escalation;

Phase 11: Testing UI Actions

Step 11.1: Query Existing UI Actions

Find all UI actions for a table:

Tool: SN-Query-Table
Parameters:
  table_name: sys_ui_action
  query: table=incident^active=true
  fields: sys_id,name,action_name,order,form_button,list_banner_button,condition
  limit: 50

Find UI actions by name:

Tool: SN-Query-Table
Parameters:
  table_name: sys_ui_action
  query: nameLIKEapprove^active=true
  fields: sys_id,name,table,condition,client
  limit: 20

Step 11.2: Testing Checklist

Pre-Testing:

• [ ] UI Action is active
• [ ] Table is correct
• [ ] Location is set (form_button, list_banner_button, etc.)
• [ ] Condition returns true for test scenario
• [ ] Scripts have no syntax errors

Functional Testing:

1. Visibility Test:

   • Does button appear when condition is true?
   • Does button hide when condition is false?
   • Is button visible to correct roles only?

2. Client Script Test:

   • Does onclick validation work?
   • Are error messages displayed?
   • Does confirmation dialog appear?
   • Does form submit correctly?

3. Server Script Test:

   • Is record updated correctly?
   • Is redirect working?
   • Are work notes added?
   • Is audit trail created?

4. Security Test:

   • Can unauthorized users access the action?
   • Can users bypass client validation?
   • Are server-side role checks in place?

Step 11.3: Debug Server Script

Add Debug Logging:

Tool: SN-Update-Record
Parameters:
  table_name: sys_ui_action
  sys_id: [action_sys_id]
  data:
    script: |
      // Debug logging
      gs.info('[DEBUG] UI Action: escalate_incident started');
      gs.info('[DEBUG] Current user: ' + gs.getUserName());
      gs.info('[DEBUG] Current record: ' + current.number);

      try {
        // Your logic here
        current.escalation = parseInt(current.escalation) + 1;
        current.update();

        gs.info('[DEBUG] Escalation updated to: ' + current.escalation);

      } catch (e) {
        gs.error('[DEBUG] Error: ' + e.message);
      }

      action.setRedirectURL(current);

Check Logs:

Tool: SN-Query-Table
Parameters:
  table_name: syslog
  query: messageLIKE[DEBUG] UI Action^sys_created_on>javascript:gs.minutesAgo(10)
  fields: message,level,sys_created_on
  limit: 50

Phase 12: Local Script Development

Step 12.1: Sync UI Action Script Locally

Download script for local editing:

Tool: SN-Sync-Script-To-Local
Parameters:
  script_sys_id: [ui_action_sys_id]
  script_field: script
  local_path: /Users/developer/servicenow/ui_actions/escalate_incident_server.js
  instance: dev

Download onclick script:

Tool: SN-Sync-Script-To-Local
Parameters:
  script_sys_id: [ui_action_sys_id]
  script_field: onclick
  local_path: /Users/developer/servicenow/ui_actions/escalate_incident_client.js
  instance: dev

Step 12.2: Directory Structure

Tool Usage Summary

| Operation | MCP Tool | Notes | |-----------|----------|-------| | Create UI Action | SN-Create-Record | sys_ui_action table | | Update UI Action | SN-Update-Record | Modify script, condition | | Query UI Actions | SN-Query-Table | Find by table, name | | Get Schema | SN-Get-Table-Schema | Understand available fields | | Download Script | SN-Sync-Script-To-Local | Local development | | Execute Test Script | SN-Execute-Background-Script | Debug server logic |

Best Practices

• Descriptive Names: Use clear, action-oriented names (e.g., "Escalate to Management")
• Consistent Order: Use standardized order numbers (100, 200, 300)
• Always Validate: Both client-side (user experience) and server-side (security)
• Use Conditions: Hide irrelevant buttons instead of showing disabled ones
• Add Comments: Document the purpose and any dependencies
• Role-Based Access: Always restrict sensitive actions
• Audit Trail: Add work notes for all significant actions
• Error Handling: Wrap server scripts in try-catch blocks
• Test Thoroughly: Test all conditions, roles, and edge cases
• Version Control: Sync scripts locally for version control

Troubleshooting

Button Not Appearing

Symptom: UI Action button not visible on form/list Causes:

1. UI Action is inactive
2. Condition evaluates to false
3. Wrong location flag set
4. User lacks required role

Solution:

Tool: SN-Query-Table
Parameters:
  table_name: sys_ui_action
  query: action_name=my_action
  fields: active,condition,form_button,table

Check active=true and verify condition logic.

Client Script Not Executing

Symptom: Nothing happens when clicking button Causes:

1. JavaScript syntax error
2. client field not set to true
3. onclick is empty

Solution:

1. Check browser console (F12) for errors
2. Verify client: true
3. Test onclick script in browser console

Server Script Failing

Symptom: Form submits but no action occurs Causes:

1. Server script syntax error
2. Permission error
3. Missing current.update()

Solution:

Tool: SN-Query-Table
Parameters:
  table_name: syslog
  query: levelINerror,warn^sys_created_on>javascript:gs.minutesAgo(5)
  fields: message,source,sys_created_on
  limit: 20

Redirect Not Working

Symptom: Stays on form or goes to wrong page Causes:

1. Missing action.setRedirectURL()
2. Invalid redirect target
3. Client returning false before submit

Solution:

• Verify action.setRedirectURL(current) at end of server script
• For custom URLs, ensure valid format
• Check client onclick returns true or submits form

Condition Errors

Symptom: Button appears/disappears unexpectedly Causes:

1. Condition syntax error (fails silently)
2. Reference field not loaded
3. Type mismatch (string vs number)

Solution: Test condition in background script:

Tool: SN-Execute-Background-Script
Parameters:
  script: |
    var current = new GlideRecord('incident');
    current.get('[sys_id]');

    // Test your condition
    var result = current.state == 7;  // Your condition
    gs.info('Condition result: ' + result);
