Finding comparable products

[Pfoster]

Following issue:
I have a table (Visual) where I have Customer-Product combinations to improve in terms of Margin (created via a ranking...). Now, the user should be able to click in this visual on an article, and in a second visual, he should get (if existing) the top 3 Customer-Product combination (excluding the selected one) and the total average of all comparable Customer-Product combination. 
I tried to  build a measure like this:

Top3Vergleichsartikel =
VAR AktuellerSchluessel = SELECTEDVALUE(Artikel[VergleichsSchlüssel])
RETURN
    TOPN(
        3,
        FILTER(
            ALL(Artikel),
            Artikel[VergleichsSchlüssel] = AktuellerSchluessel &&
            NOT Artikel[ArtikelNr] IN VALUES(Artikel[ArtikelNr])
        ),
        [Marge],
        DESC
    )

(Vergleichsschlüssel = Key build by EntityCode & Article Code)

But the Selected Value is not working with a Measure, so I am struggeling, how to get the Top3 (and ideally the average of all the "Vergleichsschlüssel"-Combinations). 
Is there a workaround how to get it?

Hi @Pfoster ,

You're close. The issue is that SELECTEDVALUE inside a measure doesn't always behave as expected when used in a visual context that returns multiple rows. To get the top 3 comparable products excluding the selected one, you’ll want to restructure the logic a bit.

Here’s a cleaner approach:

1. Create a separate measure to capture the selected Vergleichsschlüssel:

SelectedKey =
MAX(Artikel[Vergleichsschluessel])

This works better than SELECTEDVALUE when used in visuals with single selection.

2. Then use that in your TopN calculation:

TopVergleichsartikel =
VAR SelectedKey = [SelectedKey]
RETURN
CALCULATETABLE(
    TOPN(
        3,
        FILTER(
            ALL(Artikel),
            Artikel[Vergleichsschluessel] = SelectedKey &&
            NOT Artikel[ArtikelNr] IN VALUES(Artikel[ArtikelNr])
        ),
        [Measure]
    )
)

3. For the average of all comparable products:

AvgVergleichsartikel =
VAR SelectedKey = [SelectedKey]
RETURN
CALCULATE(
    AVERAGE([Measure]),
    FILTER(
        ALL(Artikel),
        Artikel[Vergleichsschluessel] = SelectedKey &&
        NOT Artikel[ArtikelNr] IN VALUES(Artikel[ArtikelNr])
    )
)

Make sure your visuals are set up to allow single selection on the main table so the context flows correctly.
