How to do it...

To complete this recipe, do the following:

1. Create the following measures:

Row Count = COUNTROWS('R09_Table')

Permutations = 
    VAR __Table = 
        SELECTCOLUMNS(
            'R09_Table',
            "__Key1",'R09_Table'[DimKey1],
            "__Key2",'R09_Table'[DimKey2],
            "__Key3",'R09_Table'[DimKey3]
        )
RETURN
    COUNTROWS(DISTINCT(__Table))

2. On a Report page, create a Card visualization and place the Row Count measure into the Fields area of the visualization.
3. On the same Report page, create a second Card visualization and place the Permutations measure into the Fields area.

We can see that the Permutations measure has correctly identified that ID 1 and ID 10 are the same.
