Calculate percentage based on two different tables

[Anonymous]

Hello,

I have two tables, one that shows all the people who did the annual medical examination required by the company (table Medical_Exams), and other that has the total number of employees in the company (table Employees). They follow this structure:

table: Medical_Exams

ID	Name	Exam_Date
1	David	10/12/2020
2	Lynn	09/11/2020
3	Leo	01/08/2020
4	Luna	03/02/2020

table: Employees

ID	Name	Departament
1	David	A
2	Lynn	B
3	Leo	C
4	Luna	A
5	Alex	A
6	Lisa	C

I want to make a simple percentage of all the people who already have done their medical exams and show it in a table view in my dashboard, separated by department.

The end result in my dashboard should be a table like this:

Departament	Percentage
A	66,66 %
B	100 %
C	50 %

I've already created a calculated column in the "Medical_Exams" table that uses a LookUpValue to get the person's department based on the ID column, but I can't create a measure that does this percentage calculation based on two tables.

Can someone help me?

Hi  @Anonymous  ,

Here are the steps you can follow：

1. Create measure.

Percentage =
var _1=CALCULATE(COUNT('Employees'[ID]),FILTER(ALL('Employees'),'Employees'[ Departament]=MAX('Employees'[ Departament])))
var _2=COUNTX(FILTER('Employees',[Name] in SELECTCOLUMNS('Medical_Exams',"1",[Name])),[ID])
return
DIVIDE(_2,_1)

2. Result:

You can downloaded PBIX file from here.

Hi @Anonymous 

You should create a relationship between both the tables on ID column.

Also, IF you already have a column for dept created then use the below measure.

_pcnt  = 

DIVIDE(CALCULATE(COUNT(Medical_Exams[id]),ALLEXCEPT(Medical_Exams, Medical_Exams[Departament])),
CALCULATE(COUNT(Employees[id]),ALLEXCEPT(Employees, Employees[Departament])),0)

Once this measure is created click on the measure name and change the format to percentage and give 2 decimal precision.
