Pivot Table - Incorrect Partial Sum

[#1]

Hi,

I was using Pivot table to do some calculations. But it does return correct partical sum for me. Please refer to below table. In the "Total" row, it gives me a number which is not equal to the real sum of "Total Cost" column.

In the "Total Cost" column, my code is like: sum(Item Cost) * count(Item)  and I tried sum( total <Item> Item Cost) but didn't work. Can anyone help me on it? Thanks!

AREA	Item	Item Cost	Total Cost = Item Cost *Unit	Unit
West	A	$13,581	$13,581	1
West	B	$27,303	$27,303	1
West	C	$113,845	$113,845	1
West	D	$13,480	$13,480	1
West	E	$10,000	$20,000	2
West	F	$35,625	$249,375	7
West	G	$5,864	$5,864	1
West	H	$207,494	$207,494	1
West	I	$5,707	$11,414	2
West	J	$80,737	$80,737	1
West	K	$6,119	$6,119	1
West	L	$4,874	$24,370	5
West	M	$27,035	$27,035	1
West	N	$8,000	$32,000	4
West	O	$42,708	$42,708	1
West	P	$10,000,000	$1,120,000,000	112
Total			$1,508,668,766	142

This is because it is not summing the rows, but calculating total Item Cost, then multiplying by the total Count. You want the sum of rows, in this you need different formula for total. You'll need aggr and dimensionality like:

if(dimensionality() =1, sum([Item Cost]) * sum(Unit), sum(aggr(sum([Item Cost]) * sum(Unit), Item)))

This is one that works in my example. For yours, maybe:

if(dimensionality() =1, sum(Item Cost) * count(Item), sum(aggr(sum(Item Cost) * count(Item), Item)))

Please find attached for example.

Hope this helps!

EDIT: You should be able to get away with just:

sum(aggr(sum(Item Cost) * count(Item), Item))

sum([Item Cost]*Unit)
