Add field to active SFMC Data extension

Question

Can you add additional fields to an active Data extension? These data extensions are currently being used to populate Active Journeys so I was not sure if I could add additional fields to the DE.

Answer 1

You can add a column on the property screen of the data extension in Subscribers. You cannot add a non-nullable column though.

You can do this in the UI or via SOAP API
