Notice how the map automatically zooms when you run a report?
That is the default behaviour of the system, so that the user automatically sees the entire extent of the selection resulting from running the report.
To lock the map in place before running a report:
- Click the "Lock extent" padlock icon in the bottom right corner of the map.
This forces the map to stay at it's current zoom scale and position, but all features will still be selected from your report, even if you can't see them on your screen.
