@ClaudiaGallegos since I don't know what modules the client owns, @WayneSchulz point may be more or less valid. I don't think BoM is going away but true WO is still a legacy module.
The transfer, btw, of the completed items would only be at the top level bill so there won't be any individual components to transfers, they'll have been consumed during the production entry process (parent/component whse).
