+# GlideRecord Conditional Clone
+
+## Description
+This snippet clones an existing record in a ServiceNow table while allowing optional field overrides.  
+It is useful for duplicating incidents, tasks, or custom records and modifying specific fields such as `assigned_to`.
+
+## Prerequisites
+- Server-side context (Background Script, Business Rule, or Script Include)
+- Access to the table
+- Familiarity with GlideRecord and sys_id
+
+## Note
+
+- Works in Global Scope
+- Server-side execution only
+- Ensures sys_id and system fields are not copied to avoid conflicts
+- Returns the sys_id of the new record, or null if cloning fails
+
+## Usage
+```javascript
+// Clone an incident and assign it to a new user
+cloneRecord('incident', 'abc123sysid', {assigned_to: 'new_user_sysid'});
+
+// Clone a task without changing any fields
+cloneRecord('task', 'xyz789sysid', {});
+```
+
+## Output
+```
+Record cloned successfully. New sys_id: <sys_id>
+```
+
+## Tips
+
+- Use fieldOverrides to update only specific fields without manually modifying the cloned record
+
