DAX measure for COUNTIF and across two seperate tables

[Anonymous]

Hi all,

I am basically trying to integrate a report from two seperate tables. Those two tables do not have an identity key linked to each other. So in excel, this could be simply done by using countif(criteria1,criteria2) like below:

But how can I use dax measure(not calculated columns) to calculate this count value? 

Your help would be much appreciated.

Hi @Anonymous,

In your scenario, you can create a calculated table to return teh count value like below:

Table = SUMMARIZE('Table2','Table2'[week],'Table2'[platform],"Count",COUNTROWS('Table2'))

Then create a measure use LookupValue() function:

Measure 2 = LOOKUPVALUE('Table'[Count],'Table'[week],CALCULATE(MAX('Table1'[week]),FILTER('Table','Table'[week]=MAX('Table'[week]) && 'Table'[platform]=MAX('Table'[platform]))),'Table'[platform],CALCULATE(MAX('Table1'[platform]),FILTER('Table','Table'[week]=MAX('Table'[week]) && 'Table'[platform]=MAX('Table'[platform]))))
