UNION to be applied after visual filtering (slicer)

[Anonymous]

Hi guys,
I have a long table of Products having various attributes - size, color, etc. I would like to have a matrix to "benchmark" (compare) particular product's attributes against according attributes of another small subset of products.
So, I duplicated my Products table to Products Benchmarks and then created a 'Union Table':

Union Table = UNION(Products, 'Products Benchmarks')
and created a visual matrix for this table.
I also created 2 slicers - one against Products to select single "benchmark" product and another against 'Products Benchmarks'. But currently they do not affect the matrix. What I want, is that the matrix should contain product selected by 1st slicer and subset of products selected by 2nd slicer (so the UNION should be basically applied to tables AFTER applying visual filtering).

Hi @Anonymous ,

The cause is that there is no relationship among your tables.

Please Create and manage relationships in Power BI Desktop.

In addition, it is suggested to understand the Unpivot related content.

Then, you can create a matrix visual like so:

@Icey,
I'm not sure how relationship can solve my issue.
I assume, you meant 'Products' to 'Union Table' and 'Products Benchmarks' to 'Union Table' relationship in this case (both by Product Name field). If I do it this way, then the final visual (matrix for 'Union Table') shows the intersection of what's selected by 2 slicers (i.e. products selected in both slicers simultaneously), whereas I need the union of what's selected by 2 slicers (i.e. products selected in at least one of 2 slicers).

Hi @Anonymous ,

Please check:

1. Create a measure.

Measure =
IF (
    MAX ( 'Union Table'[Product Name] ) = SELECTEDVALUE ( Products[Product Name] )
        || MAX ( 'Union Table'[Product Name] )
            IN VALUES ( 'Products Benchmarks'[Product Name] ),
    1
)

2. Put it on "Filters on this visual" of your table visual.

3. Test.

Best Regards,

Icey
