Same card access timings on different dates

[samoberoi]

Hi

I have got the data where i needed to take the Min(First Access card scan) and Max(Last Access card scan) for each date for each employee and i needed to count that 4 different sites and in total, so i put the distinct count on Min and Max. However, when i put the filter on it and choose an employee who e.g. would have come on 21st Dec and scanned the card on entry at 8.30 AM and would have left and scanned out at 5.30 PM and on the next day on 22nd Dec would have scanned in the access card again at 8.30 AM and would have scanned out the card at 5.31, it gives me MIN only once because the time is same 8.30 for both dates and gives me Max correctly since the timings are different for exit.  The formulas i used are as following:

For calculating MIN ---  

Min = CALCULATE(

        MIN(Table(Time column),

        FILTER(ALLEXCEPT(Table,

        Table[Date column],

        Table[Card Number],Table[Sites column]),

        Table[In/Out column] = "IN"))

For Max --- 

Max = CALCULATE(

        MAX(Table(Time column),

        FILTER(ALLEXCEPT(Table,

        Table[Date column],

        Table[Card Number],Table[Sites column]),

        Table[In/Out column] = "OUT"))

Then to calculate the count of these MIN & MAX i used ;

SUMX(VALUES(Table[Card Number] )  ,CALCULATE(distinctCOUNT(Table[Min] )))

SUMX(VALUES(Table[Card Number] )  ,CALCULATE(distinctCOUNT(Table[Max] )))

So, how can i overcome this issue where it gives only one count for the same scan timing for two or more dates because distinctcount is applied and it should, instead, give me the distinct count for each day.

Hope i could be able to explain it better.

WIll be thankful for the help.

Hi, @samoberoi,

if a card is scanned on multiple sites on a date, it should count as 1? Assuming this is the case, you can write your measures like this:

MeasureNumberOf_IN =
VAR _tmp =
    SUMMARIZE (
        CALCULATETABLE ( 'Table', 'Table'[In/Out] = "In" ),
        'Table'[Card_id],
        'Table'[Date]
    )
RETURN
    COUNTROWS ( _tmp )
