In cards, except for Domo App cards and notebook cards, you can restrict card editing access to the card owner and users with an "Admin" security role. You can do this in the Details view for the card. Users without card editing access cannot edit the data for any card type or connect new data.
To restrict editing in the Details view,
Click the card to open its Details view.
Check the Only the owner and administrators can edit this card box.
If this setting has already been checked and you are not the owner or have an "Admin" security role, you do not see this checkbox or the accompanying text in the Details view. To get editing access for this card, you must either be assigned as the owner or be given an "Admin" security role.
