How to enable maintain stock field after creating any item

Hi Team,

I have created one item but forget to keep as maintain stock and now this filed i cannot change

Two options :

  1. You will either have to delete all transactions i.e. All sales, purchase and stock documents involving this item.

  2. If that is too expensive, create a new item with different item code but same details. Later you can disable this item and all should be good.

Thanks for your support.
