Hello @amitgajkal2007 

As per your question has stated "Dax Query",

Below is the complete DAX code without doing any manipulation in PQ.

Step : Create a Calculated Table for Supporting purpose. Below is the code.

 SupportingTable =
UNION(
SELECTCOLUMNS(
'Table',"Teams",'Table'[team1]
),
SELECTCOLUMNS(
'Table',"Teams",'Table'[team2]
) )

Step : Use the below code for your output in DAX studio or DAX query view in Power BI desktop

  EVALUATE
 VAR _2 = 
 SELECTCOLUMNS(
 SUMMARIZE(
 UNION(
SUMMARIZECOLUMNS( 'Table'[team1] ),
  SUMMARIZECOLUMNS( 'Table'[team2] 
  )
  ), 'Table'[team1]
 ), "@Teams",'Table'[team1] )
VAR _3 = 
 ADDCOLUMNS(
    _2,"MatchCount", 
    CALCULATE( COUNT( SupportingTable[Teams] ), FILTER( SupportingTable, SupportingTable[Teams] = [@Teams] ) ),
    "Wins",CALCULATE( COUNT('Table'[winner] ), FILTER( 'Table','Table'[winner] = [@Teams] ) )
 ) 
RETURN
_3

I am trying to use above (mentioned in DAX query) code in a measure but i am not able to get it. 

This is a reference table which i have build...actual tbale has 4 table, like 20 columns and realted with each other. 

I am not able to use unpivot option if i use it then it create havoc in other dashboards (the slicer simply doesnt filter).

thank you but if you can let me know how i can use it above query in Dax measure then i will use the analogy on actual data. 

Thank you

Hi @amitgajkal2007 
The first step is to transform the table to vertical to make the analysis easier.

You can do it with the "unpivot" option of PQ

Then you will get the table as in the picture :

From here you can create 2 simple dax measures :

1. For matches :

matches = COUNTROWS('Table')

2. For wins:

wins = CALCULATE([matches],SELECTEDVALUE('Table'[Team])='Table'[winner])

Result :

pbix is attached, you can follow my steps at pq and dax.

Thats good one....i spent hours to figure it out using DAX. Prbolem with this is that it forms many to many relationship that is difficult to handle
Is there a solution using DAX? (Just Curious)

Hi @amitgajkal2007 
Happy to help 🙂 Why many to many,
it is just 1 table..
According to DAX, I see that @sanalytics gave a solution.

[amitgajkal2007]

Unpivoting creates a havoc on other reports. the slicers simply stop to work and doesnt filter. 

hence i was asking for DAX approach. I have 4 tables, 20+ columns and 20k+ rows. 

Thanks
