Problem with date recognition in Power BI - powerbi

Question

I'll explain my problem with an example:
I have three tables: one of dates, another of employees and another of departments.
There are two relationships:
dim_date[date_id] -> dim_employee[start_date_id]).
dim_department[department_id -> dim_employee[current_department_id]
dim_employee
name
current_department_id
start_date_id
Employee 1
1
20210701
Employee 2
2
20210701
Employee 3
2
20210901
Employee 4
1
20220201
Employee 5
2
20220201
dim_department
department
department_id
Purchase department
1
Sales department
2
I want to count how many employees each department had, for example, in February 2022 (using a slicer).. I've tried this:
num_employees_purchase_department =
CALCULATE(
DISTINCTCOUNT(dim_employee[employee_id]),
dim_employee[current_department_id]=1
)
However, since the relation is made through start_date_id, I only get the new hires of each department (one for the sales department and one for the purchase department) and not the total number of hired personnel.
The result that I'm looking for:
Employees in Purchase Department: 2
Employees in Sales department: 3
Thank you so much!

Answer 1

Try to make dim_date - dim_employee relationship inactive (in Data model view) and add an extra condition into your measure:
CALCULATE(
DISTINCTCOUNT(dim_employee[name]),
dim_employee[start_date_id] <= MAX(dim_date[date_id])
)
Don`t forget to use USERELATIONSHIP() inside your other measures where active dim_date - dim_employee relationship is necessary.
