SSRS – Create child group in same column below parent

A few months ago I was developing a report and wanted a child group in the same column below its parent.  I did tried quite a few combinations of inserting and deleting of groups, rows and columns until I finally found the right way to do it.

This week I wanted a similar report and decided to write down the steps to accomplish that, otherwise simple task.  The example was made in SQL Server Reporting Services 2008 R2.

We start by creating the parent group:

Then we create the child group:

In the parent insert row inside the group above:

This is how it will look like after creating the row inside above group:

Drag and drop to move the parent group field above the child field in the next column:

Delete the, now empty, column where the parent field previously was:

You’re done!  The child group is now below its parent:
