Hello all
I am struggling quite a lot with the following case. What I want to achieve is to create a column (important) per row that calculates the ratio of a value of that row, to the total by a group. Below is an example with excel with the formula:
So, the highlighted column is what I want. For example row 2 , the 11,8 is calculated as a the value (B2) to the sum of the cars . The reason I need a column is that I want to use these weights later for creating another column.
When I create the following formula alone in Power BI to get totals per group, it works fine:
Sum_per_group = CALCULATE(SUM(RawData[Sales),RawData[Type]=RawData[Type])
If i then enter the value , so to find the ratio , as per below, I get only "Nan" ! (I added only the [Sales]/ )
Ratio = [Sales] / CALCULATE(SUM(RawData[Sales),RawData[Type]=RawData[Type])
What am I doing wrong? 😕
Solved! Go to Solution.

You can try to create a calculated column as below. See attached pbix file.
Ratio To Type = RawData[Sales] / CALCULATE ( SUM ( RawData[Sales] ), ALLEXCEPT ( RawData, RawData[Type] ) )

Hi @phoenix20,
Try this clculated column formula
=SUM(Data[Sales])/CALCULATE(SUM(Data[Sales]),FILTER(Data,Data[Type]=EARLIER(Data[Type])))
Hope this helps.
Hi @phoenix20,
Try:
SalesbyGroup = CALCULATE(SUM('Table'[sales]),ALLEXCEPT('Table', 'Table'[Type]))
Ratio = DIVIDE([Total Sales],[SalesbyGroup])
This should give you the desired outcome.
Rgds,
Dave
