You can have a chart in agile with multiple attributes set for the bar lengh and when you view the chart you can change the attribute and see different attributes on the chart but when you go to print the chart it only ever prints the first attribute in the drop down. You will have to manually change the chart so the attribute you want to print is first in the list in order to print it. A better way to do this would be to just print a seperate page in the resulting .pdf
You will get this error if you try to move an SBM item with the report mover with a Sprint selected on the Right side of the screen as the target in the drop down. The purpose of the report mover tool is to move items into Product Backlogs, Release Backlogs or Backlogs under a Product and not straight into a Sprint. After moving the items to one of these backlogs you would then use Agile to put the items into Sprints.
Notice the status bar in the lower left of IE says Done. Now change the Sprint by using the drop down. If you pick one in the recently used list the status bar won't change but if you use the Browse Tree button and pick one the status bar will reflect the currently selected Sprint.
