Hi @Anonymous ,

I think that this request might be better in the developer forum so I have moved it there. Also, I think a bit more explanation is going to be needed as to what you are truly trying to do - what is the actual thing that you are trying to do, from a logic perspective?

Hi @collinq ,

Thanks for the response.

Am trying to figure out sum of customer count in each month.

Let say in 31 jan 2021 active customer count is 2000,then feb there is no customer addition and customer count in 28 feb is 2000.So here there is no change in count ,i will not get the data from source,because we pulling data that have a change.In this case there is no record for particular operator in Feb but i want show count in visual that is same as january.Again the if the march month also dont have any change,i want show same figure as in january.

Hi @Anonymous

I think you want to create a measure to show rolling total by month.

Here I build a sample.

Build a date table by dax.

Date = VAR _T = ADDCOLUMNS ( CALENDAR ( DATE ( 2021, 01, 01 ), DATE ( 2021, 05, 31 ) ), "Year", YEAR ( [Date] ), "Month", MONTH ( [Date] ) ) VAR _T1 = ADDCOLUMNS ( _T, "Last Date each Month", MAXX ( FILTER ( _T, [Year] = EARLIER ( [Year] ) && [Month] = EARLIER ( [Month] ) ), [Date] ) ) RETURN _T1

Measure:

Rolling Total = SUMX(FILTER(ALL('Sample'),'Sample'[Date]<=MAX('Date'[Last Date each Month])),'Sample'[QTY])

Result is as below.

Hi @Anonymous

Try this code.

Latest QTY = VAR _LatestNotBlankDate = MAXX ( FILTER ( ALL ( 'Sample' ), 'Sample'[Date] <= MAX ( 'Date'[Last Date each Month] ) ), 'Sample'[Date] ) VAR _LatestQTY = CALCULATE ( SUM ( 'Sample'[QTY] ), FILTER ( ALL ( 'Sample' ), 'Sample'[Date] = _LatestNotBlankDate ) ) RETURN _LatestQTY

Result is as below.

Hi @Anonymous ,

Thanks for the response.

I had altered the messure because i want to make some filters in visuals,so i remove ALL function,please correct me if am wrong.

Also i can see there is no relationship between sample table and date table,it will be help ful if you can explain how its working and when am adding relation the data goes wrong.

Latest QTY =

VAR _LatestNotBlankDate =

MAXX (

FILTER (

'Sample' ,

'Sample'[Date] <= MAX ( 'Date'[Last Date each Month] )

'Sample'[Date]

)

VAR _LatestQTY =

CALCULATE (

SUM ( 'Sample'[QTY] ),

FILTER ( 'Sample' , 'Sample'[Date] = _LatestNotBlankDate )

)

RETURN

_LatestQTY

The above one is the result whwn am creating relationships

Hi @Anonymous

My code will show correct result whether you build relationship between Sample and Date table.

Compare mine with yours, we can see that I use All function in Filter. All function will remove all filters in Sample, calculate the result based on whole sample table. If you don't use All function result will calculate based on current row. So result should be incorrect.

For reference: Managing “all” functions in DAX: ALL, ALLSELECTED, ALLNOBLANKROW, ALLEXCEPT

Hi @Anonymous ,

Agreed with you,adding relation will give same result.

I have one more concern ,i want see visual based on some filters in sample table(Date filter working and others not).

Currently its not working,currently i have filtered based on QTY.Like this in my table i have customer names,please help to fix this

Hi @Anonymous

Which code did you use in this screenshot? I think you didn't build a relatisonship in above sample. I think you want yo show the QTY at the last day instead sum of the QTY of the whole month. Could you tell me why Jan, Feb and Mar show 2000 in your screenshot? Please show me the result you want by screenshot.

Hi @Anonymous ,

Its by my mistake,i added a duplicate row as same as original data for testing .That is the reason its showing doubled amount.

As you said i want the data as QTY at last day of each month.From your code am getting that result but the issue was i want to filter it by some colums usng slicers.

I had attache screen shot of my actual data and the code used.

1.This is the report am developing,here i want to filter values by column in Data table.

But its not considering my filters

2.Meassure i had used given below

Latest QTY =

VAR _LatestNotBlankDate =

MAXX (

FILTER (

ALL ( 'Data' ),

'Data'[SIM Summary Snapshot: Created Date] <= MAX ( 'Date'[Last Date each Month] )

Data[SIM Summary Snapshot: Created Date]

)

VAR _LatestQTY =

CALCULATE (

SUM ( Data[SIM Count] ),

FILTER (ALL( Data), Data[SIM Summary Snapshot: Created Date] = _LatestNotBlankDate )

)

RETURN

_LatestQTY

3.Data in the table
