Summarize as a Measure

Hello everyone!

I would like to generate a dynamic table relatedParts by filtering out information which is selected by the user on a slicer.

Could anyone please help me with this?

partOptions = DISTINCT(vehicle[part_exchanged]) 

selectedPart = SELECTEDVALUE( partOptions[part_exchanged], "A")

relatedParts = 
SUMMARIZE (
        FILTER (  vehicle, ( vehicle[vehicle_id] in CALCULATETABLE(DISTINCT(vehicle[vehicle_id]), FILTER(vehicle, vehicle[part_exchanged] = [selectedPart]))
            && vehicle[part_exchanged] <> [selectedPart] )  ),
        vehicle[part_exchanged],
        "count", COUNT ( vehicle[vehicle_id] )
    )
