    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, tanks for your resoponse 🙂

I tried your query, but it gives me blank as a result...

do you think this dax query makes sense to get the correct result?

Apologies. It was too late last night and seems that I missed one small detail. Please use

 

Paused Jobs =
SUMX (
    VALUES ( 'Table'[job_id] ),
    VAR MaxDate =
        CALCULATE ( MAX ( 'Table'[timestamp] ) )
    VAR LastRecord =
        CALCULATETABLE ( 'Table', 'Table'[timestamp] = MaxDate )
    VAR LastStatus =
        MAXX ( LastRecord, 'Table'[status] )
    RETURN
        IF ( LastStatus = "PAUSED", 1 )
)

 

and yes, for each job id we are finding the max date then we count it only if it is PAUSED

    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..!
