CALICULATED COLUMN RANGE SELECTION

Good day,

I)  I need to give  range for  measure in Analytic view & How to create "Expression" in  Caliculated column.

      Eg : amount  ( 100,200, -10, 1100, -40 )

         i need to give range on ( -10 to 100). Dynamically

II)  can i give range for measure  dynamically at run time of report  using INPUT Parameters how ?

III) can we give range for measures dynamically in IDT or WEBI ?

Best Regards,

Naga.
