Hi I think u need to create an expression in such a way that nothing is selected  change ur expression to select 3 with rank funciton.

for example if u have  Year, Quarter, Month  Date.

Expression 1: select the top 3 values when year, quarter , date and month writing IF conditions. with rank<=3 expression

Second. if they select anything from calendar try to  display all the values with regualt expression.

If still u need some help post with a  sample QVW file with what  selections u want to display top 3  by default .

Thanks

use calculated dimension like

=if(aggr(Rank(Sum(Sales))<=3,Country),Country)

[MK_QSL]

If you want to show TOP 3   Customers for each Quarter... use below

Dimension

IF(Aggr(Rank(SUM(Sales),4),Customer, Quarter)<=3, Quarter)

IF(Aggr(Rank(SUM(Sales),4),Customer, Quarter)<=3, Customer)

Select Suppress When Value is NULL

Expression

SUM(Sales)
