Count Values from two Fact tables with blanks

[rmeng]

Hello,

I have a star schema with 2 fact tables. I need two metrics from both tables in a new visual table:

# Distinct Count From Call ID Fact1 table = DistinctCount(FACT1[CallID])

# Count of Strategies from FACT 2

The problem is that there are missing  strategies from table Fact2.

In the new visual table I need that Calls Id = null for # Count of Strategies metric when strategies don´t exists. 

Can you help me with this?

Hello @rmeng. You could do something like this:

# Number of Strategies (FACT 2) = 
IF(
    ISBLANK(
        CALCULATE(
            COUNTROWS( 'Fact 2' ),
            TREATAS( VALUES( 'Fact 1'[Call ID] ), 'Fact 2'[Calls ID] )
        )
    ),
    "null",
    CALCULATE(
        COUNTROWS( 'Fact 2' ),
        TREATAS( VALUES( 'Fact 1'[Call ID] ), 'Fact 2'[Calls ID] )
    )
)

I attached a .pbix file here, in case it's helpful.

Hi @rmeng ,

According to your screenshot, I think you couldn't make all relationships active or you will get a cycle in data model.

For reference: Manage relationship

Here I choose to inactive "DIM Date"[Date] to "FACT 2"[Date].

You just need to add Strategie column in it and use count function in values field. In your table visual, it will show blank if there is no strategie in Fact2. 

Or create a easy measure to show null.

Measure = 
VAR _Count = COUNT('FACT 2'[Strategie])
return
IF(ISBLANK(_Count),"null",_Count)

Result is as below.
