Security Filter Causes Incorrect SQL

Security Filter Causes Incorrect SQL

Security Filter Causes Incorrect SQL

(OP)
I've got a strange situation with a report that I have created.  Under my login which does not have any security filters, the sql for the report is correct:

select a11.SBU  SBU,
    a11.Company  Company,
    a11.ReservationCarrier  ReservationCarrier,
    a11.ReservationOrigin  ReservationOrigin,
    a11.ReservationDestination  ReservationDestination,
    a11.CardType  CardType,
    a12.Month  Month,
    a12.MonthName  MonthName,
    a12.CalendarYear  CalendarYear,
    sum(a11.DetailDeposit)  WJXBFS1
from Res_Summary_Accounting_Detail a11
    join Dim_Date_Reservation_Depart a12
      on  (a11.ReservationDepartDate = a12.ReservationDepartDate)
where (a11.ReservationDepartDate = CONVERT(datetime, '2006-03-07 00:00:00', 120)
 and a11.CancelDate is null)
group by a11.SBU,
    a11.Company,
    a11.ReservationCarrier,
    a11.ReservationOrigin,
    a11.ReservationDestination,
    a11.CardType,
    a12.Month,
    a12.MonthName,
    a12.CalendarYear


Under a user's login that does have a security filter on the SBU attribute, the sql for the report is incorrect.  Notice how the sql performs a distinct select, leaves out the sum on the metric and needlessly joins to all of the dimension tables:

select distinct a11.SBU  SBU,
    a11.Company  Company,
    a11.ReservationCarrier  ReservationCarrier,
    a11.ReservationOrigin  ReservationOrigin,
    a11.ReservationDestination  ReservationDestination,
    a11.CardType  CardType,
    a14.Month  Month,
    a14.MonthName  MonthName,
    a14.CalendarYear  CalendarYear
from Res_Summary_Accounting_Detail a11
    join Dim_SBU a12
      on  (a11.Company = a12.Company)
    join Dim_Carrier_Reservation a13
      on  (a11.ReservationCarrier = a13.ReservationCarrier)
    join Dim_Date_Reservation_Depart a14
      on  (a11.ReservationDepartDate = a14.ReservationDepartDate)
    join Dim_City_Reservation_Destination a15
      on  (a11.ReservationDestination = a15.ReservationDestination)
    join Dim_City_Reservation_Origin a16
      on  (a11.ReservationOrigin = a16.ReservationOrigin)
where (a11.ReservationDepartDate = CONVERT(datetime, '2006-03-07 00:00:00', 120)
 and a11.ActivityType = 'DEP'
 and a11.SBU in ('ADV', 'AMV'))


Has anyone ever seen this situation?  I've tried changing the dimensionality on the metric to no avail.  If I run the report under my login and answer the SBU prompt to essentially replicate what the user's security filter is doing automatically, the sql still looks good.  I just don't understand what the security filter is doing.  The SBU attribute used by the security filter looks fine.

Thanks.
