Hello @satishNG,
I suggest you to use my following logic.
1 - Trigger on Lifecycle State :
Use the Identity Attributes Changed to trigger your workflow (documentation: Workflow Triggers - SailPoint Identity Services)
Filter String : $.changes[?(@.attribute == 'cloudLifecycleState' && (@.newValue == 'inactive' || @.newValue == 'terminated'))]
2 - Action : Manage ServiceNow Ticket
Use the Manage ServiceNow Ticket Action (documentation: Workflow Actions - SailPoint Identity Services)
Configure all information required inside the Action like Caller, Type, ServiceNow Tenant API, Description,…
3 - Operator: Success
Finish the workflow logic by a Success Operator.
I send you my workflow attached to this reply 
!
