Help with getting the maximum value from calculated table containing measure column

Hi... i only want to display the maximum of each group for the calculated table below.  For example, for 0000-1040I =32, for 1040O=32, 10413=43, etc.  When i use MAX it complains the Counter per BID ...

    Hi miguelsus2000 ,

    Miguel, I tested your sample data. Maybe the following formula can help you. For why you get the sum value, I think it is caused that my sample is too simple. It is filtered by other columns in your actual data.

     

    MAXX = 
MAXX (
    SUMMARIZE (
        FILTER (
            ALLSELECTED ( 'LoRaBlePayload (2)' ),
            'LoRaBlePayload (2)'[Content.BeaconIdentifier]
                IN FILTERS ( 'LoRaBlePayload (2)'[Content.BeaconIdentifier] )
        ),
        'LoRaBlePayload (2)'[Content.BeaconIdentifier],
        'LoRaBlePayload (2)'[PartitionKey],
        "New", [Count per BID]
    ),
    [New]
)

    Best Regards,

miguelsus2000 ,

 

Use the below meaure to get the Max value for each group:

Measure = CALCULATE(Max(Table[Value]),ALLEXCEPT(Table,Table[Category]))

    I forgot to add the table, but the Count per BID is a caluclated measure which MAX doesn't like.

     
     
     

    max4 = CALCULATE(Max('LoRaBlePayload (2)'[Count per BID]),ALLEXCEPT('LoRaBlePayload (2)','LoRaBlePayload (2)'[Content.BeaconIdentifier]))
     
    Error: Column 'Count per BID' in table 'LoRaBlePayload (2)' cannot be found or may not be used in this expression.

      miguelsus2000 ,

       

      where does Count per BID field come from? Is it coming from same table like 'LoRaBlePayload (2)?

        Thie Count per Bid is below:

        Count per BID =
        CALCULATE(
            COUNTA('LoRaBlePayload (2)'[Content.BeaconIdentifier]),
            FILTER(
                ALLSELECTED('LoRaBlePayload (2)'[Content.Rssi]),
                ISONORAFTER('LoRaBlePayload (2)'[Content.Rssi], MAX('LoRaBlePayload (2)'[Content.Rssi]), DESC)
            )
        )
         
         
        This tells me how many readings i've received for each partition key for each content.beaconidentifier.  Now, i only want the max for each group of content.beaconidentifier,t hen show all 3 columns for that max.  Eg. from the calculated table above, i want to show:
         
        Content.beaconidentifier         Max Count         Partitionkey
        0000-1040l                                32                      7b....58
        0000-1040O                               32                     7b....58
        0000-10413                                43                     7b....58
         
        if i dont need to use Count per Bid, it's ok, but needed a way to verify the max
         
        Any ideas?
