Extract Visibility
Extract visibility defines whether the extract is Private, meaning only the user who created it can see and run it, or Public, meaning all users with appropriate data access can see and run it.
Private Extracts
When you first create an extract, it is created as a private extract. Private extracts can only be viewed and run by the user who created them. You must have access to a view and Participant (Read) or better access on a viewpoint in order to create or copy a private extract. There are no permission requirements to edit or delete a private extract.
You run private extracts from the Viewpoint Extract report, and they can be run to a file only. See Extracts Reports.
Public Extracts
You cannot create a public extract directly, but if you have Owner or Metadata Manager permission on the dimension, you can promote a private extract to public so that other users can see and run it. You can also copy, edit, or delete a public extract. See Creating, Copying, Promoting, and Deleting Extracts
You can run public extracts from the Applications list or the Viewpoint Extracts report, and they can be run to a file or a global connection. See Running Extracts.
