The "include all reporting units" option when exporting Financial Reports should default to "Yes" instead of "No". The default of "No" will not include all of the data for the report, and if you set to "yes" when exporting then it doesn't remember your selection the next time you export a report.

This parameter did not exist when exporting Financial Reports in 1611 (7.1), but is new in our 8.1.3 PU24 instance. Screenprint attached
