In the management policies screen we have 4 choice for the look for better product to sell in retail store option
which i need to choose if i want my subsidiary who have supermarket store selling farming product (livestock) of another farming subsidiary that i own 100%
presently i use own and parent option but the AI didn't try to buy stuff of my other farming sub
they have a thing i don't do right? or is a game limitation?
I don't think there is such an option. It would be great if there was one though! Perhaps I've been doing it all wrong, but I'm not sure you can.
