[Koha] Enable holds

[Olugbenga Adara]

Hello all,

How do i enable hold on items? When i try to place a hold on an item koha says  "Sorry, none of these items can be placed on hold." i have checked my rules and i cant see anywhere i should enable holds.

i am using koha 3.01.00.032 

Thanks for your help.
