How to count number of employees of each department?

[spagad6263]

Hi,

I am new to DAX, and hope someone can provide advice how to use DAX?

Below are 2 tables - [Employee] and [Department], and I would like to have a new measure (or column) in Department table to show number of employee of each department (highlighted in grey). Any suggestions are most appreciated!

Perfect and this is exactly what I need. I used the second method, and it works! Thanks so much for the help.

Are you able to have a brief explanation about below?

ALLEXCEPT ( Employee, Employee[Dept_id], Department[Dept_Name] )

here we have used ALLEXCEPT as modifier, which will remove all the filters from table specified in the first argument and keeps only the filters on the columns specified in the following arguments.

You can refer following link to better understand how allexcept can be used in different ways.

There are two methods to calculate count of employees in each department.

Method 1:
step1:
Create table visual and add dept id(from employee table), dept name(from department table) and employee id(from employee table).

step2:
summarize employee id as Count or distinct count (according to your data).

Method 2: (Using Measure/Calculated column)
DAX Code : 

Number of employees =
CALCULATE (
COUNT ( Employee[Employee_id] ),
ALLEXCEPT ( Employee, Employee[Dept_id], Department[Dept_Name] )
)
