🎓 Scenario-Based Question

Use Case: Prevent Incident Submission Without Attachment

We want to make sure a user cannot submit an Incident unless at least one file 📎 is attached to the form.

🛠 Steps to Implement:

1. Create a Business Rule
   • ✅ Active
   • ✅ Advanced
   • ✅ Before Insert
   • 📄 Table: incident
2. Write the script and save:

   (function executeRule(current, previous /*null when async*/) {
       var gr = new GlideRecord("sys_attachment"); 
       gr.addQuery("table_sys_id", current.sys_id);
       gr.query();
       if (!gr.hasNext()) {
           gs.addErrorMessage("📎 Attachment is required to submit this Request");
           current.setAbortAction(true);
       }
   })(current, previous);
         

3. Test: Try to submit a new Incident without an attachment. You’ll see an ❌ error message, and the record won’t be created.

💡 Pro Tip:

Instead of just blocking the submission, you can also guide users with a UI Policy to visually prompt them to attach a file before submission.
