+# Auto-populate Location Variables in ServiceNow Catalog Items
+
+## Overview
+
+This solution automatically populates location-related variables (Location, City, State, and Country) in Service Catalog items based on the logged-in user's profile information.
+
+## Prerequisites
+
+- Users must have their location field populated in their user profile (`sys_user.location`)
+- Location records (`cmn_location`) must have city, state, and country fields configured
+
+## Components
+
+### 1. Script Include
+- **Name:** LocationUtilsAjax
+- **Type:** Client Callable
+- **Purpose:** Retrieves user location details from server
+
+### 2. Catalog Client Script
+- **Type:** onLoad
+- **Purpose:** Fetches logged-in user's location data and populates catalog variables
+
+## Installation Steps
+
+### Step 1: Create Script Include
+
+1. Navigate to **System Definition > Script Includes**
+2. Click **New**
+3. Set **Name:** `LocationUtilsAjax`
+4. Check **Client callable**
+5. Paste the Script Include code
+6. Click **Submit**
+
+### Step 2: Create Catalog Variables
+
+Create these variables in your catalog item:
+
+- `location` - Single Line Text
+- `city` - Single Line Text
+- `country` - Single Line Text
+- `state` - Single Line Text
+
+### Step 3: Create Catalog Client Script
+
+1. Open your **Catalog Item**
+2. Go to **Related Links > Configure > Catalog Client Scripts**
+3. Click **New**
+4. Set **Type:** `onLoad`
+5. Paste the Catalog Client Script code
+6. Click **Submit**
+
+## Testing
+
+1. Ensure test user has location set in their profile
+2. Log in as test user and open the catalog item
+3. Verify variables are automatically populated
+4. Check browser console (F12) for any errors
+
+## Configuration Notes
+
+- Variable names in the script must match your catalog variable names exactly (case-sensitive)
+- Make variables **Read-only** if users shouldn't modify them
+
+## Security
+
+- Script validates user input
+- Only retrieves data for the current logged-in user
+- No sensitive data exposure beyond user profile
