AileneA,

Unfortunately what you propose doesn't work for me.  If I go to the unclassified report, and then filter out any classes, nothing changes in the report.  The unclassified P&L is the unclassified P&L, whatever classes I choose to customize the report with result in no changes.

The reason is not because there is nothing labelled with those classes.  I believe that the class filter doesn't work within a unclassified report, period.
