Filtering two tables with many-to-many relationship

[elguestca1]

Hello,

Let's say I have 3 tables, 1 Fact table and 2 Dimensional tables Account Nr and Article Nr.
Fact table has relationship with Account Nr by ID on many-to-many relationship and also the same Fact table has many-to-many with Article Nr by ID.

I have two visuals (tables). On the left (Article and sum(from facts)) and on the right (Account and sum (from facts)). 
The issue is that I need to find those Accounts which does not have Article and in this case I can only do it by pressing it one by one. 

Is it possible to recieve all the Account Nr which does not have Article?

Example bellow:

What I get when I choose Account Nr with Article 

What I need is to find all those who has no article

Thank you.

@elguestca1 , I think you need an approach very similar to this
