How to get list of item occurance with condition

[Anonymous]

Hi All,

i have table dataset in the below format,

ID	Date	App name	Duration
100	01-12-2022	METER	10
100	01-12-2022	Instagram	20
101	01-12-2022	FB	20
102	01-12-2022	METER	10
100	02-12-2022	METER	10
101	02-12-2022	Whatsapp	30
102	02-12-2022	METER	10
100	03-12-2022	Whatsapp	30
101	03-12-2022	METER	10
101	03-12-2022	Instagram	20
102	04-12-2022	METER	10

First part was to calculate ATS = duration/distinctcount(ID) for each day excluding "METER" app. I used below DAX for the calculation

ATS  =

AVERAGEX

(

    SUMMARIZE(FILTER(table, table[Appname] <> "METER"), table[Date],"Sum_duration",SUM(table[Duration]),"Reach", DISTINCTCOUNT(table[ID]))

,

DIVIDE([Sum_duration],[Reach]))

Above DAX gave me ATS result for each day excluding "METER" app.

Second part of problem was to get list of ID that gives me only "METER" data for the month (all days considered). That means for the above dataset ID 102 gives "METER" data only for all the 4 days considered. Other ID reported data for other apps as well so can be excluded.  

Please help what DAX to use.

Was able to solve above prob in SQL for one day taken at a time:

SELECT  ID

FROM tabel
WHERE Date='2022-12-01'
GROUP BY ID
HAVING MIN(app name)=MAX(app name)
AND MIN(app name) in ('METER')

Can somebody help the above same in DAX method ?

HI @Anonymous,

You can use the following measure formula to check current id related records within current date ranges and return flag:

flag =
VAR currDate =
    MAX ( 'Table'[Date] )
VAR appList =
    CALCULATETABLE (
        VALUES ( 'Table'[App name] ),
        FILTER (
            ALLSELECTED ( 'Table' ),
            YEAR ( 'Table'[Date] ) = YEAR ( currDate )
                && MONTH ( 'Table'[Date] ) = MONTH ( currDate )
        ),
        VALUES ( 'Table'[ID] )
    )
RETURN
    IF ( "METER" IN appList && COUNTROWS ( appList ) = 1, "Y", "N" )

Thank you so much for the response. So i was applying the same measure that you have given but my actual dataset is huge so keeping ID, app name and date is not loading the measure. (data that i pasted in question was just a sample).

Is it possible to show the flag against each ID in visual avoiding the app and date from the visual ?

Hi @Anonymous,

In fact, this expression will check at the year month level based on current ID group.

If you only use ID as category without other fields, the formula will get wrong results because the aggregate row contexts have matched with multiple type of flags.
