Nipun Garg Feb 8, 2017 8:23 PM (in response to Koushik Neelakantha)Hi Koushik try to use to fixed LOD calculation so that quantity and difference column would not be aggregated before multiplication
hope this will work

Mahfooj Khan Feb 8, 2017 9:59 PM (in response to Koushik Neelakantha)Hi Koushik,
Not sure this will work or not? I haven't validated this calculated field.
WINDOW_SUM((SUM(IIF([Category]='Books',[Profit],0))
SUM(IIF([Category]='Cases',[Profit],0)))*
SUM([Quantity]))
Compute using Table (down)

Let me know If it works
Whenever you've such requirement where you've do some complex calculation then try to split your calculation in smallsmall results. Like in your case first try to calculated the Profit for Books and Cases separately and validate on canvas check correct output is coming or not. If you're getting correct then you're on right path
Once done then get the difference. Then after multiply with quantity. Then sum it up using WINDOW(). I alway follow this method and it works.

Mahfooj Khan Feb 8, 2017 11:39 PM (in response to Koushik Neelakantha)Okay
I don't have tableau access right now else I must answer with correct calculation.
Are you able to calculated Profit for Books and Cases separately?
Split the calculations and check till get
What this calculated field is returnning?
[Books]: SUM(IIF([Category]='Books',[Profit],0))
[Cases]: SUM(IIF([Category]='Cases',[Profit],0))
Diff: [Books][Cases]
Diff*Qty: [Diff]*sum([Qty]) //I've doubt at Qty
Then window_sum([Diff*Qty])
Or we've to take help from LODs
Do you've any other field on rows? Books/Cases values from on field right?
Can you show me exact format of your original data set? How it looks?
