The purchase order cannot be created on Hold

Hello gurus,

I have a doubt, when I want to create a purchase order (transaction ME21N) adopting a purchase requisition, the button "Hold" dissapear.

Any reason why the button "Hold" is missing when adopt the purchase requisition to the purchase order?

I need to save the purchase order on Hold after the adopting, but, I cannot find the button.

Could you help me please a.s.a.p.?
