DAX to count based on another column

[kbandito]

Hi, I am looking for a DAX to count the number of brands available in BBB when I selected AAA.

I need a DAX because i need to build charts that can breakdown the count by category.

Table 1: Location

Main location	Within 3km
AAA	BBB
AAA	BBB
BBB	CCC

Table 2: POI

Location	POI	Category
BBB	LV	Luxury
BBB	GAP	Fashion
BBB	Kids	Kids

Hi @kbandito ,

You can try to create a measure and put it into a card. When you select AAA, the card returns the number of brands 3 km away from you.

Count =
CALCULATE (
    COUNTROWS ( 'POI' ),
    FILTER (
        'POI',
        [Location]
            = CALCULATE (
                MAX ( 'Location'[Within 3km] ),
                FILTER (
                    'Location',
                    [Main location] = SELECTEDVALUE ( Location[Main location] )
                )
            )
    )
)

You can check more details from here.

@kbandito - Maybe:

Measure =
  VAR __Search = MAX(Location[Within 3km])
RETURN
  COUNTROWS(FILTER('POI',[Location]=__Search))

Or

Measure =
  VAR __Search = MAX(Location[Within 3km])
RETURN
  COUNTROWS(DISTINCT(SELECTCOLUMNS(FILTER('POI',[Location]=__Search),"brands",[Category])))

Otherwise, please provide additional details.

Hi, the first measures kinda works, but i think the MAX function limits it to show only 1 location.

For example, AAA will have 5 locations in the Within 3km list. Now the measure is only showing the POI count for just 1 location, i will need it to show POI count for all 5 locations when AAA is selected.
