Bug 189751 cube enhancement: Groups and Summaries category; an empty summary field is being created.
Based on bug Id# 187412: Cube builder enhancement While reviewing the cube builder enhancements, I found some things that are not updated as the mock up. Please see the attached document. Under Groups and summaries category: 1. If new a cube, under 'groups and Summaries' category, by default an empty summary field is being created.

Primary Dataset has to be listed as (Primary)
