partial string filter based multiple selectedvalues

DokterT 

I'm not sure exactly how you want to use this so I've created one of the alternatives. With it you can see the code pattern and adapt it as necessary.

1. Place FactT[Group] in a table visual

2.  Place SlicerT[Group] on a slicer

3. Create this measure. :

Show measure =
COUNTROWS (
    FILTER (
        DISTINCT ( SlicerT[Group] ),
        SEARCH ( SlicerT[Group], SELECTEDVALUE ( FactT[Group] ), 1, 0 ) > 0
    )
) + 0

4. Set the measure above as a filter for the table visual. Choose Show then value is greater than 0. This will filter out the unwanted rows in tehe visual.

See it all at work in the attached file with some simplified tables
