How to find the total contribution % of each Department towards Total Number?

[HassanAshas]

Hi, I have records of Employees working in different Competencies and Practices. For each employee, I have Billed and Unbilled Hours.

The data looks something like this, 

Emp_ID	Emp_Name	Competency	Practice	Billed Hours	Unbilled Hours
25	Sam	Data & Integration	ML	110	5
26	Emma	Development	Python	75	25
27	Owen	Data & Integration	Data Engineering	95	30
28	Isabella	Design	UI/UX	25	70
29	Liam	Data & Integration	ETL	85	40
30	Nora	Development	Java	0	125
31	William	Data & Integration	BI	45	60
32	Ava	Development	.NET	0	100
33	Elijah	Design	Interaction Design	35	50
34	Sophia	Data & Integration	Cloud	55	35
35	Lucas	Development	JavaScript	0	120
36	Olivia	Design	Visual Design	15	85
37	Noah	Data & Integration	ML	125	15
38	Grace	Development	Ruby	0	110
39	Henry	Design	Usability Testing	5	95
40	Mia	Data & Integration	ETL	65	45
41	Aiden	Development	C++	0	130
42	Ella	Design	UI/UX	30	60
43	Jacob	Data & Integration	BI	80	20
44	Chloe	Development	Python	0	130

My aim is to find Unbilled Hours Ratio. Formula of Unbilled Hours Ratio is, 

Unbilled Hours Ratio = Unbilled Hours / (Billed Hours + Unbilled Hours)

This, I have already implemented using following DAX, 

Unbilled Hours Ratio = 

var _UnbilledHours = SUM(Employees[Unbilled Hours])
var _BilledHours = SUM(Employees[Billed Hours])
var _TotalHours = _UnbilledHours + _BilledHours

var _Result = 
    DIVIDE(
        _UnbilledHours, 
        _TotalHours
    )
return _Result

This is giving me the value of 61.5%. 

Now, I want a Bar Chart that shows % values each "Competency" and each "Practice" is contributing towards this 61.5%. 

For now, I have the following visual, 

This basically shows me the Unbilled Hours Ratio for each Competency. I don't want that, I want to find the percentage value each Competency contributed towards the 61.5%. 

The similar will be done for Practices as well (so if I drill down to all the Practices for one Competency, it will show me the % values each Practice contributed towards the total % percentage value of the Competency Unbilled Hours Ratio) 

Can anyone help in creating a DAX for this scenario?

Hi , @HassanAshas 

Thanks for your sample test .pbix first !And accoridng to your description, you want to " find the percentage value each Competency contributed towards the 61.5%. ".

In my understanding, if you want to obtain the corresponding Competency's contribution to 61.5%, then I think you only need to consider the percentage of the Unbilled column, not the Billed column.

Here are the steps you can refer to :
We can create this measure :

Measure = var _sub_total =  CALCULATE( SUM('Employees'[Unbilled Hours]) , ALLSELECTED('Employees'[Practice]))
var _total  = CALCULATE( SUM('Employees'[Unbilled Hours]) , ALLSELECTED('Employees'[Competency]))
return
DIVIDE( SUM('Employees'[Unbilled Hours]) ,  IF( ISINSCOPE('Employees'[Practice]) , _sub_total , _total) )

Then we can put it on the bar chart and the result is as follows:

If this method does not meet your needs, you can provide us with your special sample data and the desired output sample data in the form of tables, so that we can better help you solve the problem. (You can also upload you sample .pbix [without sensitive data] to the OneDrive and share with the OneDrive link to me ! )

Thank you for your time and sharing, and thank you for your support and understanding of PowerBI!
