This is my first line that brings back the top ten (U5 is my Customer field):
U5#Top.CustomMemberList(BRName = CustomerRank, MemberListName = Ranked, RankType = Top, RankCount = 10, LoopMemberFilter = U5#root.Base, DataCellToRankMemberFilter = Cb#CustomerData:E#|CVEntity|:P#|CVParent|:C#USD:S#|CVScenario|:T#|CVTime|:V#|CVView|:A#Sales:F#|CVFlow|:O#Top:I#Top:U1#|CVUD1|:U2#|CVUD2|:U3#|CVUD3|:U4#|CVUD4|:U5#|CVUD5|:U6#|CVUD6|:U7#|CVUD7|:U8#|CVUD8|)
And my second row for total sales is: U5#Top:Name(Total Sales).
So I'm looking for a single line that is essentially...total sales - sum of the top ten results. I'm sure it's something simple.
