SQL query to DAX Measure conversion

Anonymous — Mon, 16 Aug 2021 17:24:55 GMT

I have the following SQL query that I have converted to DAX Measure

SELECT
RowNumber = ROW_NUMBER() OVER (PARTITION BY SSN ORDER BY EOMDate DESC)
FROM [TransArchive].dbo.AGGR_Transaction_ChannelUtilization
WHERE EOMDate BETWEEN @dteEOMBegin AND @dteEOMEnd

DAX Measure :::

Index = CALCULATE(COUNTROWS('Member Channel Utilization'), FILTER(ALLSELECTED ('Member Channel Utilization')

,FILTER('Member Channel Utilization','Member Channel Utilization'[Report Date]<= EARLIER('Member Channel Utilization'[Report Date]))

,FILTER('Member Channel Utilization','Member Channel Utilization'[EDWCustomerID]= EARLIER('Member Channel Utilization'[EDWCustomerID]))))

Please Note :::: ReportDate = EOMdate and SSN =EDWCustomerID

I have used ALLSELECTED becasue I want the rownum value to change based on the date range filter and /or any other filter selected by the user on the PowerBI report. When I run the query I get the following message "Too Many Arguments were passed to the FILTER Function. The Maximum argument count for the function is 2"....
Could you please let me know how to make this DAX work . Thanks in advance

Hey Anonymous ,

it's not possible to nest FILTER functions. Just combine in one filter what you want to filter.

I guess you wanted something like this:

Index = CALCULATE( COUNTROWS( 'Member Channel Utilization' ), FILTER( ALLSELECTED( 'Member Channel Utilization' ), 'Member Channel Utilization'[Report Date] <= EARLIER( 'Member Channel Utilization'[Report Date] ) && 'Member Channel Utilization'[EDWCustomerID] = EARLIER( 'Member Channel Utilization'[EDWCustomerID] ) ) )

If you need any help please let me know.

If I answered your question I would be happy if you could mark my post as a solution ✔️ and give it a thumbs up 👍

Best regards

Thanks selimovd

I have actually Succesfully created the Index column Measure now .....But now I want to use this measure to create a New Measure Marker Column ....expected result is something like this

Report Date	EDWCustomerID	Index	Marker
8/31/2020 0:00	3	1	0
9/30/2020 0:00	3	2	0
10/31/2020 0:00	3	3	0
11/30/2020 0:00	3	4	0
4/30/2021 0:00	3	5	1
8/31/2020 0:00	4	1	0
9/30/2020 0:00	4	2	0
10/31/2020 0:00	4	3	0
11/30/2020 0:00	4	4	0
4/30/2021 0:00	4	5	1
8/31/2020 0:00	5	1	0
9/30/2020 0:00	5	2	0
10/31/2020 0:00	5	3	0
11/30/2020 0:00	5	4	0
4/30/2021 0:00	5	5	1

Here I want to mark the row with max value in the Index column per Reporte Date per EDWCustomerid

Hopefully this makes sense. Thanks in advance.
