I have a basic SharePoint (2013, I think) site (I am a SharePoint novice...) with a List, to which a large number of users have access. All Users need to be able to: - View all Items - Add a new Item
A workflow automatically launches upon Item creation which generates a unique Item 'Reference' (based on the Item ID) and adds this to a 'Ref.' column after Item creation.
Therefore, all Users have been given custom permissions to View, Add and Edit Items in the List.
However, I would like to restrict their access to only be able to Edit Items which THEY have created themselves (not other users' Items).
How can I do this? At the moment, the Users' permissions which allow them to Edit list Items seems to override the List level setting which says 'Edit Items created by the User'.
