+Let field technicians request parts from a field service order.
+
+A **Request Parts** button on the FSM order creates a purchase request
+linked to the order (origin and requester pre-filled), and a stat button
+shows all purchase requests originated by the order. Deleting an order
+keeps its purchase requests, only unlinking the reference.
