Use

You can protect objects and object versions for a particular status by setting the Protected or Protected Version indicator on the Create Status screen in a status profile.

If you set the Protected indicator, you can display an object with this status but you cannot edit it. If this is the case, the system displays this information on the detail screen of the object. Although you cannot edit a protected object, you can still:

You cannot create or delete objects in a protected folder. It is possible, however, to edit objects in such a folder (provided that the objects themselves are not protected).

If you set the Protected Version indicator, you can edit an object with this status. However, when you save any changes that you make, the system creates a new version of the object. The original version cannot be changed. If the object is a document, the system creates a new version when you save your changes or when you check in the document.

It is also possible to protect field groups of a generic object that is assigned to a status profile.
