Reference : Attribute types : Link
  
Link
The link attribute contains a reference to another element. The target element can be located in any module in any workspace. If the source and target elements are in different workspaces, the target element can only be viewed, and not modified, even if you have administrator access to the workspace of the target element.To display a linked element, click the link. What you see depends upon your permissions:
▪ For administrators, the target element is displayed with all of the information available in the module.
▪ For other users, the target element is displayed according to the settings of the display view that a user has access to. If there are no display views, the element is displayed according to the settings of the first available view.
In elements that are opened by clicking the links, the attributes and editing options differ depending on whether you are an administrator.
When you generate a URL link to any element, the URL link only identifies the element and not the view. When a user clicks on that URL link, the element is displayed in the first valid view that the user has access to. For example, consider that user1 has access to view1 and view2, and user2 has access to view2 only. When user1 sends the link to user2, the element is displayed in view2 for user2.
