    Hi yjk3140 
    Final solution is as follows

     

     

    Paused Jobs =
SUMX (
    VALUES ( 'table1'[job_id] ),
    VAR MaxDate =
        CALCULATE ( MAX ( 'table1'[datetime1] ) )
    VAR LastRecord =
        FILTER (
            CALCULATETABLE ( 'table1' ),
            'table1'[datetime1] = MaxDate
                && 'table1'[job_active_status] = "PAUSED"
        )
    VAR Result =
        IF ( NOT ISEMPTY ( LastRecord ), 1 )
    RETURN
        Result
)

    Ok, please try

    CASH_IPD =
COUNTROWS (
    CALCULATETABLE (
        SUMMARIZE (
            BI_OSR_Revenues,
            BI_OSR_Revenues[Encounter_No],
            BI_OSR_Revenues[Payment_TypeName],
            BI_OSR_Revenues[InvoiceNo]
        ),
        BI_OSR_Revenues[Tran_Month] = 3,
        BI_OSR_Revenues[Tran_Year] = 2022,
        BI_OSR_Revenues[Payment_TypeName] = "CASH (IPD)",
        NOT ISBLANK ( BI_OSR_Revenues[admission_Date] )
    )
)

Hi tamerj1! your DAX query looks logically correct and smart but I don't think MAX function works for the date column here..I'm not getting any result but blank.

Do you think there is another approach to solve this query that I can try?

 

Thank you so much for your help!

Hi yjk3140 
Just now I've prepared a sample file and it works just fine. However, this for sure depends of the filter context. The details that you might think they don't matter they actually do.

    Hi tamerj1 yes the query looks really clear but I'm not sure why it doesn't work on my dataset...

    This is a screenshot of the actual table I have below

    do you think the format of the date matters here..? if so, is there anyway to get the result I want with the timestamps in this format?

     

    really appreciate your help..!

      Is it a text or date format?

        Hi tamerj1

        It's a date/time format!

    Hi tamerj1 !

    can we use count function intead of sum and if functions? 

    sth like this..(not sure if this query would make sense)

    Paused Jobs =
    VAR MaxDate =
            MAX ( 'table1'[timestamp] )
    VAR LastRecord =
            CALCULATETABLE ( 'table1', 'table1'[timestamp] = MaxDate )
    VAR LastStatus =
            MAXX ( LastRecord, table1'[job_active_status] )
    VAR countid = CALCULATE( DISTINCTCOUNT(ops_log[job_id]), LastStatus = "PUASED")
     RETURN countid
