Percent of total in a hierarchy (DAX)

Posted on by • Posted in Basic script • Tagged , • Leave a comment

Getting percent of total in a hierarchy is easy in DAX. In this example we will use the Geography hierarchy.

Geography 1

Then I will create 2 calculated measures in my model.

TotalSales2:=calculate(SUM([Order Quantity]);ALL('Geography'))

And 

Ratio To Total:=Sum([Order Quantity]) / [TotalSales2]

The last one should be formatted as percent.

Then process and deploy your model.

If you open an Excel pivot you should see something like this

Hierarchy Excel 2

If you summarize “Ratio To Total” in this pivot you will get 100 %.

When changing the pivot to show city instead of country the percent still works as intended.

Hierarchy Excel 3

I did not show all the cities in the screenshot above

How to use “RANKX”

If you want to rank your result in DAX you can use the RANKX function.

Below is a sample

DEFINE
MEASURE 'Internet Sales'[Rank] =
RANKX (
ALL ( 'Product'[Product Name] ),
SUMX (
RELATEDTABLE ( 'Internet Sales' ),
'Internet Sales'[Internet Total Sales]
)
)
EVALUATE
FILTER (
ADDCOLUMNS (
VALUES ( 'Product'[Product Name] ),
"Product Rank", 'Internet Sales'[Rank],
"Sales amount", 'Internet Sales'[Internet Total Sales]
),
[Sales amount] <> 0
)
ORDER BY 'Internet Sales'[Rank]

Please note the filter that removes the empty rows.

Here is the resultset
