Internal sales order cycle in spares management

Hi everyone,

During our implementation raised a business case regarding the items movement between the main warehouse to technician warehouse. And after doing some research I need to confirm that my understanding is correct:

1. It is possible to create internal sales order to transfer parts between main and technician sub-inventories when both sub-inventories are in the same organization.
2. Can make an internal sales order during parts requirement ordering if the source sub-inventory is with type manned warehouse.
3. Internal sales order will be automatically created when the user press save button in parts requirement HTML UI.
4. The system will automatically create an approved PR in purchasing, and create internal sales order in OM with status (entered or booked) depend on the profile option setting.
