+Auto-Populate Short Description (Client Script)
+Overview
+
+This client script automatically updates the Short Description field in ServiceNow whenever a user selects a category on the form. It improves data consistency, saves time, and ensures that short descriptions remain meaningful and standardized.
+
+How It Works
+
+When a user selects a category such as Hardware, Software, or Network, the script automatically prefixes the existing short description with a corresponding label (for example, “Hardware Issue –”).
+This makes incident records easier to identify and improves the quality of data entry.
+
+Configuration Steps
+
+Log in to your ServiceNow instance with admin or developer access.
+
+Navigate to System Definition → Client Scripts.
+
+Create a new Client Script with the following details:
+
+Table: Incident
+
+Type: onChange
+
+Field name: category
+
+Copy and paste the provided script into the Script field.
+
+Save the record and make sure the script is active.
+
+Testing
+
+Open any existing or new Incident record.
+
+Select a category such as Hardware or Software.
+
+The Short Description field will automatically update with the corresponding prefix.
+
+Benefits
+
+Speeds up data entry for users.
+
+Maintains consistency in short descriptions.
+
+Reduces manual effort and human errors.
+
+Enhances clarity in incident listings and reports.
