SubTotal Category Remaining Amount: How to calculate difference between two columns
How to display the value of "Remaining Amount' in subtotal category:
I have the following scenario, using a Pivot table Displaying the budget amount and actual amount along with remaining amount.
for every subcategory I do not want to display remaining amount if either value budget or Actual value is 0.
However I will still like to display a value for remaining amount if either the Budget or Actual value exist (My understanding is that I the value rolls up and adds to display subtotal values).
Below is the formula's I used to calculate Remaining Amount in BeastMode calculation.
CASE
when
sum(case when `Transaction_Type` = 1 then `Amount` else 0 end) =0
or
sum(case when `Transaction_Type` = 0 then `Amount` else 0 end) =0
then 0
else
sum(case when `Transaction_Type` = 1 then `Amount` else 0 end)

sum(case when `Transaction_Type` = 0 then `Amount` else 0 end)
end
Thank you

Hi,
Instead of 0 in your code can you put '' in the beast mode. So if budget or actual value is 0 then '' .
Does that give you what you need?

Hi @msharma
Because the way pivot tables behave and the fact that subtotals are an all or nothing setting what you're looking to do isn't possible at this time.

@msharma ,
@rahul93 is partially correct, if you put a '' in your ELSE clause you will convert your beastmode into a string. It therefore wouldn't format or behave like a number after that point. probably not desireable.
To get 'nothing' as Rahul is recommending, you can however use ELSE NULL
sum(case when `Transaction_Type` = 1 then `Amount` else null end)  or sum(case when `Transaction_Type` = 1 then `Amount` end) =0
Now that said you have to be careful with null
if you take
5  NULL
the result witll be NULL

SOLUTION
test if your amounts net to 0 if so replace with null
case when sum(case when ... then amount else 0 end)  sum(case when ... then budget else 0 end) = 0 then null else sum(case when ... then amount else 0 end)  sum(case when ... then budget else 0 end) end
THAT SAID. WHAT YOU'RE ASKING FOR IS LOGICALLY INAPPROPRIATE
Null and 0 are not the same thing.
If i had 5 dollars and spent 5 dollars i have zero dollars left.
That's different from I spent nothing and i had no budget therefore the value should be null.

Hi, using a '' doesn't convert the field into a string field. I just tested it and it works as a numeric field. See screenshots
Thanks
