Count number of consecutive times

[Matthew9900]

I have this table that has the information about the result of an event that can be "Won" and "Lost".

I would like a measure in DAX that calculates the number of consecutive times that "Won" is achieved without "Lost" appearing.

In this example it would be 4

Result

Won

Won

Lost

Won

Lost

Won

Won

Won

Won

Lost

Lost

Hi @Matthew9900 

The solution given by @Anonymous  is great.

You can also do the 1st step with DAX as follows -create a Group COLUMN

Group = CALCULATE( COUNTX( 'Table','Table'[Index]),

                                        FILTER(ALL('Table'),'Table'[Index] <= EARLIER('Table'[Index])

                                               ),'Table'[Result]="Lost"

                            )

Hi @Matthew9900 ,

I suggest you to add an index column and then add a group column in Power Query Editor.

List.Count(
let
_Index = [Index]
in
Table.SelectRows(#"Added Index",each [Index]<=_Index and [Result] = "Lost")[Result])

New Table:

Measure:

Consecutive win times = 
VAR _SUMMARIZE =
    SUMMARIZE (
        FILTER ( 'Table', 'Table'[Result] = "Won" ),
        'Table'[Group],
        "Count", COUNT ( 'Table'[Index] )
    )
RETURN
    MAXX ( _SUMMARIZE, [Count] )

Result is as below.

Based on your description, I created data to reproduce your scenario. The pbix file is attached in the end.

Please check https://community.powerbi.com/t5/DAX-Commands-and-Tips/DAX-How-to-Count-the-Consecutive-Occurrences/...

I also tried it with this DAX function (hopefully easier)

Step1

Count Cons Won = if(CALCULATE(max('Table'[Result]),'Table'[Index]=max('Table'[Index])+1 ||'Table'[Index]=max('Table'[Index])-1)="Won",1,0)

Step 2

Cumulative ADDITION = CALCULATE( SUMX(

                                        SUMMARIZE(

                                                   'Table',

                                                    'Table'[Index],

                                                    "CUMULATIVE ADD",

                                                     [Count Cons Won]

                                                 ),[CUMULATIVE ADD]),

                                        FILTER(ALL('Table'),'Table'[Index] <= MAX('Table'[Index])

                                               )

                                )

Thank you very much ribisht17

The solution is working but it is not adequate. The objective of this measurement is to find the longest winning streak, in this example it is giving me 6, but the correct answer should be 4.

That part is there in the link that I shared with you
