Hi Krishna1990_PBI ,

 

I may be oversimplifying this, but it looks like you just want to find out the number of computers that have an [ApplicationName] LIKE "CrowdStrike".

If so, then the following should work fine:

_AppCount =
CALCULATE(
    DISTINCTCOUNT(Table2[ComputerID]),
    CONTAINSSTRING(Table2[ApplicationName], "CrowdStrike")
)

 

As you have a Table1 ONE : MANY Table2 relationship, this should calculate correctly for different selections of Table1.

 

If you don't actually need the 'LIKE' comparison, but an 'EQUALS' comparison, then it's even simpler:

_AppCount =
CALCULATE(
    DISTINCTCOUNT(Table2[ComputerID]),
    Table2[ApplicationName] = "CrowdStrike"
)

Hi Pete.

 

Thanks for the reply. 

 

I wanted to keep that measure value remain unchanged when I click any visuals from the board. Curently the value is changing.

    Ok, so the following should work:

    _AppCount =
CALCULATE(
    DISTINCTCOUNT(Table2[ComputerID]),
    FILTER(
        ALL(Table2),
        CONTAINSSTRING(Table2[ApplicationName], "CrowdStrike")
    )
)

// OR

_AppCount =
CALCULATE(
    DISTINCTCOUNT(Table2[ComputerID]),
    FILTER(
        ALL(Table2),
        Table2[ApplicationName] = "CrowdStrike"
    )
)

      I wanted to query Table2 Application Column based on Table1 Computer ID. So i used the folowing query but the measure value changes 

       

      Should i go for calculated column to overcome this scenario 

       

      _AppCount =
CALCULATE(
    DISTINCTCOUNT(Table1[ComputerID]),
    FILTER(
        ALL(Table2),
        CONTAINSSTRING(Table2[ApplicationName], "CrowdStrike")
    )
)

        I'm struggling to understand why you need to involve Table1 in your measure.

        You have [ComputerID] in Table2 that you can use to count, and you have a ONE:MANY relationship between the two tables, so all of Table1 is already included in the expanded version of Table2.

         

        What am I missing here?
