About Calculated Fields
Hi all... I'm trying to do something like this:
I've a userparameter , for example lets call it A.
Another one, lets call it B.
What I want to do is something like this:
CalculatedItem = ( (b-last(b)) / ( (a-last(a)) + (b-last(b)) ) ) * 100
B or A would be the current value and last(a) or last(b) would be the last value... Don't know if this is right... I mean I need the current value and the previous one, something like t2 - t1, in a timeline.
Thanks!
