Exclude columns in matrix from dimensional table

Hi experts!

I have a table that lists all articles (Article):

Article	Date	Value
A	01.01.2022	500
B	01.01.2022	600
C	01.01.2022	400

 

Then I have a table that lists all necessary production steps (Routing) for each article:

Article	Process Step	Description
A	01	String
A	02	String
A	03	String

 

Both tables are linked by column Article.

Then I have a table (Production) that shows me the production step status:

Article	Order Nr	Process Step
A	1	01
A	1	02
B	2	01

 

This table contains just process steps that are finished or started.

This table is linked by Article with the first table (Article).

 

Now I would like to show all necessary process steps (Routing) in a matrix as a column.

But just all process steps that are already part of table Production or planned process steps out of Routing.

 

In the end I have a simple Measure like this in values:

IF([Value]="", 0, [Value])

 

But this measure would display all process steps in column, regardless if it is a defined process step for the article.

How can I exclude columns / process steps that are not part of the selected rows / articles?
