A Data Group is a group that you create directly in the Link GUI. It must be configured to contain a list of Document Types that the group is used to give View-access to. A Data Group must subsequently be linked to a User Group in Link. The basic concept of User Groups is explained in the documentation Managing users, roles and permissions in Link .
