Sorting a Crystal report based on a running total"": Has anyone done it? (v2011)
Apparently it's not a simple thing like just sorting the report based on a regular 'ol field due to how/when running total fields are calculated during report generation (i.e., running totals are created after Sorting). Apparently it may be accomplishable via a stored procedure (with view or SQL expression?), a formula, or editing the query itself but I don't know how to do either of those for this situation. I already suggested they just dump the report to Excel like they have been, and then sort from there but it seems like their preference is for the report to automatically do the sorting.
