The Incident.rpt ootb Default Report isn't sorting the Notes in date order. This is how you can change this:
Open the Report directly in Crystal.
Where the Note is added in, in the left hand column (the grey area) Right click and chose "Change Group..."
Then find the im_incident_note and below this you will see im_serial_number. (Below, as if you were to expand a folder) Select this so that the selected field will say: "im_incident_note.im_serial_number"
Click OK, SAVE the Report and close it.
Next time you open a report in Console from Crystal you will see the notes in the correct order.
