Get union of selections from using 4 slicers

[Riya275]

Is there a way to get union of selection from 4 different slicers. 

I have tried using the method os creating disconnected tables and creating a visual level filter to get union. It however doesnt work for more than 2 slicers. 

Detailed method - https://apexinsights.net/blog/or-xor-slicing

Is there a way to scale up this method to accomodate 4 slicers?  Or is there another method?

You can extend the author's method if instead of using the OR function you use || operator - that way you can chain together as many conditions as you like. Modifying the author's code would give you

OR Filter =
IF (
    SELECTEDVALUE ( 'Data Table'[Letters] )
        IN ALLSELECTED ( Letters[Letters] ) // Checks if current letter is in slicer selection
            || SELECTEDVALUE ( 'Data Table'[Numbers] ) IN ALLSELECTED ( Numbers[Numbers] ),
    // As above for current number
    1,
    // Return 1 if value is selected in one or both of the slicers
    0 // Else return 0
)

This is not working. If I choose any two slicers it doesnt work, there is no change in the visuals. If I choose yes on two slicers and no on the other two , it still doesnt work.
