Hi Saurabh,
That's right. Whenever a production order is created, automatically a reservation gets created for components 261 movements.
You can create stock transfer reservations for 311 movement by using MF60.
In the MF60 transaction when you do the material staging with reservation it will executes with 311 movement type stock transfer reservation with 311 movement from the central storage location to the production storage location.
