Row Level Filtering in DAX

Hello,

I am looking to implement row level filtering in DAX using the userprincipalname() function. I have two data tables, one with the salary data, and another with the employee access details. If an employee is allowed to have access to the data for a department, they can view the data, if not, I'd show something like "Hidden" instead of the actual value. 

As an example if my salary data looks like this:

Salary Data:

EmployeeDepartmentSalaryLevel

And the Access Data is as follows:

EmployeeDepartment

Now, if Emp1 is viewing the report (Username() = "Emp1"), they'd see be able to see the following: 

I tried implementing this using the following measure:

Filtering = 

This gives me an error saying "Each table argument of 'Intersect' must have the same number of columns. I also tried concatenating the departments in the Access Table - so Emp1 would have departments AB, BC. Then I tried using the IN function, but that doesn't work either. 

Would anyone know how I could implement a solution to flag rows that are in another table and then show the values in a column accordingly? I'd appreciate any  help. 

Thank you!
