How to create dynamic percent measure

[firefly3224]

Updated: In the example below, I'm trying to visualize racial composition by year. When race slicers are applied, the correct % are shown. However, the % for all Asians in 2014 is incorrect.

How do I create a dynamic percent measure, so that the correct % shows even when no slicers are used?

Hi  @firefly3224 ,

Here are the steps you can follow：

1. Create measure.

divide =
var _1=CALCULATE(SUM('Table'[Count]),ALLEXCEPT('Table','Table'[Year],'Table'[Race]))
var _2=CALCULATE(SUM('Table'[Headcount]),ALLEXCEPT('Table','Table'[Year],'Table'[Race]))
return
DIVIDE(_1,_2)

2. Result.

You can downloaded PBIX file from here.

You are going to need to calulate the absolute values from which the % derives (since you have more than one row per year asians and to calculate over totals). So, what is the % of? is it the % of total headcount? If so, you need to calculate the total headcount  as a new calculated column in the data table: 

total headcount = DIVIDE( table[Headcount], table [percent])

and then calculate the % as a measure to use in the visuals:

% of total headcount =
VAR headcount =
    SUM ( Table[ Headcount] )
VAR TotalHC =
    SUM ( Table[total headocunt] )
RETURN
    DIVIDE ( headcount, TotalHC )

@firefly3224 , Make sure you have a year column, Try a measure like

divide(sum(table[headcount]), calculate(sum(Table[headcount]), filter(allselected(Table), Table[Year] =max(Table[Year]))))

Thanks @amitchandak, I've made the corrections and will tinker with the solution (new user here!)
