As per the new release, You have to create Population for one to one relationship and once you configure population with your DataExtension then immediately, your DE set to be Use as root and mapping field would come in contact configuration.

  • Thanks for your response after creating population i got the DE enabled as Root.Previously i have used Data designer for establishing root data and data relationships. Commented Jan 9, 2017 at 12:09
