When subcontracting a production order, raw materials may be sent from an internal warehouse to the subcontractor.

This idea is to add a feature to create the transfer order by selecting lines in the Production BOM and generating the transfer order.

Marking each transfer order line to the to the corresponding production order BOM should avoid creating the transfer twice. Only unmarked quantities should be suggested to create the transfers order lines.

The create transfer order function that is present on the sales line could be added production BOM/Formula lines screen with multi select available. It should be possible to add the new transfer order lines to an existing transfer order for that production order.
