When you run a static report, you can change the parameters of the data returned. For example, you can request data for only the 25 users who made purchases, but you cannot change the dimensions and measures in the report.

You can change the dimensions and measures in a dynamic report by adding, removing, and changing the orientation of dimensions and measures, and by changing the level of detail that the completed report shows. If you change a completed dynamic report, you can save the report definition with the changes as a custom dynamic report definition.
