Specified Order Grouping does not show if Distinct Count is Zero

Question

Hello,
I'm using Crystal Reports XI R2 with SQL data source. I have a cross-tab report with grouping in specified order. It's a report of applicants applying to a college. The grouping is of various majors (degrees). The report summarizes (distinct counts) the number of applicants for the groups of majors. The problem is that if the count for a group of major is zero, then that Named Group does not appear at all in the cross-tab report. I want the Name Group to appear with the count of "0".
I notice this same phenomenon with specified order grouping anywhere and not just in a cross-tab. I have tried changing "convert database/other null values to default" but nothing working yet.
Any help will be most appreciated. Thanks.

It's not a phenomenon, it's how databases and SQL works.
You didn't get any rows back for those with a zero distinct count (otherwise the count would be 1 or more, right?), so Crystal doesn't show any data for those groups.
So to display a zero for those that do not exist would reuire either advanced SQL, or manual summaries.
One method for manual summaries is to use Running Totals. Select distinct count of the applicants and group by the majors, then in the evaluate use a formula place:
{table.majors} = "Blah 1"
Creating a seperate Running Total for every group and replacing "Blah 1" with the various majors.
