How to Identify the Script Behind the Message Displayed When Applying a Template?

[KartheekG]

When I apply a template to any record in ServiceNow, a message appears at the top of the form showing that the template has been applied. I want to know where this message comes from (Business Rule, UI Action, Script Include, etc.) so I can modify or use it for my use case.

How can I find the exact script or logic that triggers this message?

Step 1: Identify the Source of the Message

1. UI Action:

   • Navigate to System UI → UI Actions.

   • Search for UI Actions on the sys_template table (the table for templates).

   • Look for a UI Action named something like Apply Template or Apply Template to Record.

   • Open the UI Action and check its Client Script or OnClick field.

2. Client Script:

   • The message is generated using the g_form.addInfoMessage() method in a client-side script. For example:

     javascript

     Copy

     g_form.addInfoMessage('Template applied successfully.');

---

Step 2: Locate the Script

1. For Templates on a Specific Table:

   • If the template is applied to a custom table (e.g., incident), check the Client Scripts or UI Actions on that table.

   • Go to the table’s form → Right-click the header → Configure → UI Actions.

2. Global Template Application:

   • The default template logic is often in the global UI Action Apply Template (sys_ui_action with name "Apply Template").

   • To find it:

     text

     Copy

     Navigation: System UI → UI Actions → Search "name=Apply Template"

   • Check the Script field in the UI Action.

---

Step 3: Modify the Message

1. Edit the Client Script:

   • If the message is in a Client Script, edit the g_form.addInfoMessage() line.

   • Example:

     javascript

     Copy

     // Original
     g_form.addInfoMessage('Template applied successfully.');
     // Modified
     g_form.addInfoMessage('Custom Template Applied!');

2. Override with a New UI Action (Recommended for Customization):

   • Clone the existing UI Action and modify the message in the clone.

   • Set Order to a higher value (e.g., 100) to override the default action.

---

Step 4: Verify Using Background Scripts

If the message is server-side (rare), check Business Rules or Script Includes:

1. Business Rules:

   • Navigate to System Definition → Business Rules.

   • Filter for rules on the sys_template table or your target table.

2. Script Includes:

   • Search for addInfoMessage in Script Includes (e.g., sys_script_include).
