Custom Total Column

[NJ81858]

Hello,

I am trying to create a custom calculation for my total column in a matrix and I'm not sure how to configure that best. My matrix looks like this currently, with the Groups being my rows and my Categories being my columns:

	Category 1	Category 2	Category 3
Group 1	0	5	12
Group 2	5	9	15
Group 3	12	2	17
Group 4	7	0	20

What I am trying to calculate in my custom total column is the percentage of values that are in Category 3 for each group. In theory I want my matrix to look like this:

	Category 1	Category 2	Category 3	% of Values that are in Category 3
Group 1	0	5	12	70.588%
Group 2	5	9	15	51.724%
Group 3	12	2	17	54.839%
Group 4	7	0	20	74.074%

I tried to create a measure that calculates this and it currently looks like this: 

VAR _numTotal = CALCULATE(

    COUNT([Value]),

        FILTER('Table', [Group] = [Group]))

VAR _numCategory3 = CALCULATE(

    COUNT([Value]),

        FILTER('Table', [Categories] = "Category 3"),

        FILTER('Table', [Group] = [Group]))

RETURN CALCULATE(

    DIVIDE(_numCategory3, _numTotal),

    FILTER('Table', [Group] = [Group]))

Any help on this is greatly appreciated, thank you in advance!

Hi @NJ81858 ,

According to your description, here are my steps you can follow as a solution.

(1) We can create a measure or calculated column.

Measure = 
var _a=CALCULATE(SUM('Table'[Value]),FILTER(ALLEXCEPT('Table','Table'[Group]),'Table'[Value]))
var _b=CALCULATE(SUM('Table'[Value]),FILTER('Table','Table'[Category]="Category 3"))
var _c=DIVIDE(_b,_a,0)
return _c

Column = var _a = IF('Table'[Category]="Category 3",'Table'[value])

var _b = CALCULATE(SUM('Table'[Value]),FILTER('Table','Table'[Group]=EARLIER('Table'[Group])))

return DIVIDE(_a,_b,0)

(2) Then the result is as follows.
