Measure Not working on Sankey Chart

[N_A_S_H]

Hi,

I am doing basic CDR Analysis. I want to use the Sankey Chart to show the flow of communication between common connections only. Common connection is defined as single dimBParty[B-Party] connected to multiple dimAParty[A-Party]. 

My data model has two dimension tables dimAParty and dimBParty connected to CDR fact table. I created a measure to filter the common connections only i.e. count distinct A-Parties per B-Party.

DistinctAPartyCount = 
CALCULATE(
    DISTINCTCOUNT(dimAParty[A-Party]),
    CDR
)

The measure seems to work fine when I use it as a filter in a matrix visual - DistinctAPartyCount > 1.

However, when I use it to filter the common connections in a Sankey Chart, the chart goes blank.
Link to the "Sample CDR.pbix" file. 
Please help with the correct measure.  Thank you.

Hi @N_A_S_H ,

You should note that your measure is placed as a filter at the visual level.

Then I tested it, and the measure filter was placed in the matrix, and it was also empty.

Please provide more details of your issue.

Hi @v-stephen-msft,

Please take a look at the second page of the report for the measure output.

Hi @N_A_S_H ,

Thanks for your reply. I reviewed a while and found that the cause.

You can observe that it's the gaps caused by issues with the order of your visual fields. The positions of A party and B party are reversed.

Similarly, your matrix has a row B-Party at the top and a column at the bottom with A-Party. Your filter is to show the value when the count of A-Party is greater than 1.

It would be more intuitive if you replaced Grand Total with a filter's metric, as follows:

For each row of the B-Party, the distinctcounting of A-Party with 03004444444 is 1 and will be filtered out. Others greater than 1 will be retained.

At this point I put A-Party in the row and B-Party in the column, as follows:

You can see that, A-Party is assigned to each row, so the distinctcounting of A-Party in each row is 1, which is the filter condition when the distinctcounting of A-Party is greater than 1, all rows will be filtered out.

Summary: This question involves the row context, if you are interested, you can refer to:

Row context in DAX - SQLBI

Context in DAX Formulas - Microsoft Support

Hi @N_A_S_H 

I dupklicated your Sankey tab and put measure and I do get some figures, not blanks.
