Adding Totals at the Bottom of Column Group in a Table

Question

I am preparing a report which has a Table in it with two ColumnGroups (dynamically generated). The StandardRelays Group is parent group and RelayConfigs group is a child of it. I wan't to print totals for each group at the bottom of respective column. Here is the Report in Design View

I am able to print the Totals for the child group (RelayConfigs) as well as parent group (StandardRelays) each on a separate row, but the issue is that the parent group total repeats as many times as there are child columns. The output view of the report can best explain what I mean.

As can be seen, the total marked in red is the total for the parent group (Bombardier Relay in this case) is repeating with the child column. What I would have liked is that the three columns merge at Total Row and output just one total (4 in this case highlighted). Is it possible to achieve this or do I have to change the layout to print column group totals as separate column?

Answer 1

Click on cells that stretch across columns to have all of them highlighted. Right Click. Merge Cells. Expression is now shared in scope of cells above it.

EDIT:

Okay you are in essence wishing to show a parent expression below it appears in a matrix. I am not certain if you can do this as a matrix on the detail level is going to be the lowest leaf of a tree structure. You can get totals as you are doing but at the lowest level the matrix is on a detail level expanding out to it's fullest. However you can quite easily populate the total by customer above it as the parent will only aggregate that which is in common with what you tell it to group on and no more. Here are two possibilities.

On your 'name' or similar column right click and choose 'Insert Rows'>(Expand to)>'Inside Group Below' then put your expression in for 'Sum(Amount)' or similar. You now with have a totals showing of the grouping of the names before the details level.

You can also expand and collapse the details level at will with a trick that will show the grouping name UNTIL you hit the '+' sign to expand it. Right click your 'date' field in the 'Column Groups' of the designer. Choose 'Visibility' on the left pane. Choose 'Hide' for 'When the Report is Initially run'. Check 'Display can be toggled by this report item' and choose your parent group of whatever the 'name' of products is.
