The Security Model in IDF
By applying security to an object, you can control which users can view the object and which users can create, change, delete or copy the object.
Basic object security allows you to control who can display or maintain an object. Advanced object security allows you to control selectively who can create, change, delete, or copy an object.
In the basic model, all of the maintenance activities are permitted to those users who are authorized to maintain the object. Use the basic security model if you want a user who can change an object to also be able to create or delete the object. Use the advanced security model if you need to restrict some users to changing the object but not creating or deleting the object.
