I've found a solution for my own issue.
I'm interested in changing the results shown for a Scrum Template report.
- Open the report in the "Project Portal" (right click on the Team
project in Visual Studio and select "Show Project Portal".
- Click on the report, e.g. Velocity.
- Click the "properties" tab on the top.
- Click the "Parameters" tab on the left. Some parameters are editable
here, e.g in my case "DoneName". I'm changing this to "Committed"
instead of "Done" so that I can see the items marked as committed.
This parameter can be make editable from the brower ui by selecting
the "Prompt User" checkbox.
