Find max in a group based on a condition

Hi there,

 

I'm looking to find MAX baseline revision no within my data. This is what I have used so far :

 

 

Pretend Project column = x 

My goal is to find max baseline revision no where cus search = 1. 

My calculated column LC Max has this :

LC Max = IF(
CALCULATE(MAX('Activity History'[Baseline Revision No]),
ALLEXCEPT('Activity History',
'Activity History'[Project]))=MAX('Activity History'[Baseline Revision No]),1,0)

 

However it returns 0 all throughout. Even when I remove Cus search as a column I'm still getting 0 in LC Max. Can anyone recommend anything else in this scenario? 

 

Thanks

    Hi kasiaw29 ,

    Based on your description, you can create this measure, put it in the visual filter and set its value as 1:

    Measure = 
VAR _max =
    CALCULATE (
        MAX ( 'Table'[Baseline Revision No] ),
        ALLEXCEPT ( 'Table', 'Table'[Project] ),
        'Table'[Cus Search] = 1
    )
VAR _br =
    SELECTEDVALUE ( 'Table'[Baseline Revision No] )
RETURN
    IF ( _br = _max, 1, 0 )

    Attached a sample file in the below, hopes to help you.

     

    Best Regards,

    I have had help on a spanish version of community. 

    I've changed my LC Max to include following: 

     

    LC Max = CALCULATE(
    MAX('Activity History'[Baseline Revision No]),
    FILTER(
    ALLEXCEPT(
    'Activity History',
    'Activity History'[Project]
    ),
    'Activity History'[CUS Search] = 1
    )
    )
     
     
    Then I have created a custom column with this:
    Max Baseline CA = IF('Activity History'[Baseline Revision No] = 'Activity History'[LC Max],1,0)

    kasiaw29 This looks like a measure aggregation problem. See my blog article about that here: https://community.powerbi.com/t5/Community-Blog/Design-Pattern-Groups-and-Super-Groups/ba-p/138149

    The pattern is:
    MinScoreMeasure = MINX ( SUMMARIZE ( Table, Table[Group] , "Measure",[YourMeasure] ), [Measure])
    MaxScoreMeasure = MAXX ( SUMMARIZE ( Table, Table[Group] , "Measure",[YourMeasure] ), [Measure])
    AvgScoreMeasure = AVERAGEX ( SUMMARIZE ( Table, Table[Group] , "Measure",[YourMeasure] ), [Measure])
    etc.

    kasiaw29 , try like

    Measure =
    VAR __id = MAX ( 'Activity History'[Project] )
    VAR __dt = CALCULATE ( MAX( 'Activity History'[Baseline Revision No] ), ALLSELECTED ( 'Table' ), 'Table'[Project] = __id )
    If( 'Activity History'[Project] = __id, 'Activity History'[Baseline Revision No] = __dt ,1,0 )

      amitchandak Not sure if this is it, please have a look at another sample data. 

      Highlighted row should be max baseline rev where cus search = 1 and that's the noly result I want to see.

        kasiaw29 , Can you share sample data and sample output in table format? Or a sample pbix after removing sensitive data.
