Always select Blank in the Filter combined with Cross Filtering

[ms_flxx]

Hello all together! 

My following question is based on this post here: Always select Blank in the Filter. Unfortunately, it does not fully cover my problem. My minimum working example is based on this for better comparability and understanding. Since I am still new to the forum here, I hope it is correct to create a new issue...

But now to my concern:

Main Question 

I would like to cross-filter my table so that a selected option in the slicer also includes all blank values (i.e. and-condition).

 

Detailled Description 

I have a table called 'Table' that contains the columns 'Year', 'Season' and 'Value':

As you can see, the columns 'Year' and 'Season' contains both, data as well as nulls. I would like to filter this table by 'Year' and 'Season' using two different slicers. Therefore I created two seperated Tables called 'Seasons' and 'Years', that only contain the respective columns 'Year' resp. 'Season':

 

 

To ensure that all blanks are selected in addition to the selected option in the slicer, I have adopted the measure from Always select Blank in the Filter

Season_Measure = IF(SELECTEDVALUE('Table'[Season]) in ALLSELECTED(Seasons[Season]) || SELECTEDVALUE('Table'[Season])=BLANK(),1,0)

Year_Measure = IF(SELECTEDVALUE('Table'[Year]) in ALLSELECTED(Years[Year]) || SELECTEDVALUE('Table'[Year])=BLANK(),1,0)

If there is no relationship between the tables, everything works as expected:

BUT: If I select the year 2021 as shown in the screenshot, then I only want the seasons that exist for this year to be displayed in the season slicer (in this case only Spring, Winter and Fall). However, if I create a relationship between the tables, the measure no longer works, which also shows me the blanks.

I very much hope that I have described my problem sufficiently and concisely. I am very happy to receive help!

Best regards, Felix

Hi @ms_flxx 

You can add a table like below. Then use these two columns in the slicers. Modify the measures to reference this new table's columns.
