Multiplier Front End (Previous/Current) field

[hkg_qlik]

Hi 

How can we create a new Field on UI without making any changes on back end script. Month and Value 1 are available. Now user wants to derive Value 2 field as shown below.

Value 2 (Feb) = Jan(Value 1) * Feb(Value 1) = 1.08*1.09 = 1.18

Value 2 (Mar) = Feb(Value 1) * Mar(Value 1) = 1.09*1.04 = 1.13

Value 2 (Apr) = Mar(Value 1) * Apr(Value 1) = 1.04*1.03 = 1.07

Month	Value 1	Value 2
Jan	1.08
Feb	1.09	1.18
Mar	1.04	1.13
Apr	1.03	1.07

Thanks!

Try this

=Sum(Value1) * Alt(Above(Sum(Value1)), 0)

or

=exp(RangeSum(Above(log(Sum(Value1)), 0, 2)))

Thanks Sunny !

=Sum(Value1) * Alt(Above(Sum(Value1)), 0)
