@Hamza Abusitta you cannot change the subsidiary structure once created, this option is locked. Only NS can do this - you have to persuade them with your business case, I have done this quite few times over the years. Remember if the companies have different functional/base currency then you will have a nightmare scenario - in that case I will not attempt it ( I have learnt my lesson unfortunately it is a tall order 😩). If all the companies have same base currency then easy sailing.
