They why do we have it in DNG?
I don't know the reason other than DNG re-uses the UI from Jazz Foundation for the project area administration.
However, this question has been asked previously on this forum and the answer has always been the same. DNG does not make use of timelines or iterations. It is not exposed in DNG artifact attributes. If you google 'jazz.net DNG and timelines' you will see the previous forum posts.
