The form design here is just like the other forms, and much simpler than the Details Master and Transaction patterns. The clever part of this is that we are thinking task-based. We are creating a workspace based on what the user does. The traditional form design from Dynamics AX 2012 was to provide all the features that the user could want, which resulted in a lot of features that most users never used. With workspaces, the concept is that most of the workspace is used regularly. The user shouldn't have to change workspace to locate a form for that task. It is also OK for a user to use more than one workspace. We want to provide everything the user needs, but without clutter.
