Hii AB ,
Top N Condition Defined in Bex Query is not supported in Webi or Xcelsius Dashboard
hence you are left with below three option .
Option 1 :
Ask the BW Consultant to Remove TOP N Condition based on a particular KF from Bex Query .
Bex Report should be sorted based on KF in Descending Order .
Bind just 10 Cell in Excel Range in Dashboard Design if report is for Top 10 records.
Option 2: Ask BW Consultant to Build a Pre Query which will contain Top n Records and same will be supported in BO Webi and Dashboard .
Option 3 : Defined Top N Logic in Webi using Top N Function and pull the same in Dashboard using Live office or BIWS .
Regards
Jeetan
