+**Auto Incident Creation from Case Email** 
+
+**Description** 
+This inbound email action automatically creates an incident record when a customer replies to a case email containing keywords like outage, crash, error, or not working. 
+The new incident links to the case as a parent and inherits caller and configuration item details. 
+
+**Use Case** 
+Ideal for CSM environments integrated with ITSM, where customer issues escalate to incidents automatically. 
+
+**How It Works**
+1. The inbound email action scans the subject and body for trigger keywords.
+2. If a match is found:
+   - A new incident record is created.
+   - The incident is linked to the case as a parent.
+   - Caller and CI are inherited if available.
+   - Work notes of both case and incident records are updated. 
+
+**Inbound Action Configuration**
+   - Table: Case[sn_customerservice_case]
+   - Action type: Record Action
+   - Type: Reply
