Sum of 2nd latest value from non-continuous selection

[thisisausername]

I have a slicer that allows users to select a week ending date(s).

The selection the user makes will not always be continuous e.g. may select w/e 31st January, 17th January, 10th January

I want to sum Total Sales for the 2nd-latest week selected, how would I do that in DAX? (so for the 17th January in the above example)

Hi @thisisausername ,

Could you tell me if your problem has been solved?
If it is, kindly Accept it as the solution. More people will benefit from it.
Or you are still confused about it, please provide me with more details about your table and your problem or share me with your pbix file from your Onedrive for Business.

Hi @thisisausername ,

In order to get the total value of the next week of the selected date, you need to create a separate date table. In Filters, set Show items when the value is 7. This is to keep the last date of the week in the slicer.

DateTable = ADDCOLUMNS(CALENDAR(DATE(2021,1,1),DATE(2021,12,31)),"WEEKDAY",WEEKDAY([Date],2))

 

Create the measure.

Total value =
CALCULATE (
    SUM ( 'MainTable'[Value] ),
    FILTER (
        'MainTable',
        WEEKNUM ( [Date], 2 )
            = WEEKNUM ( SELECTEDVALUE ( DateTable[Date] ), 2 ) + 1
    )
)

You can check more details from here.

Tips: Since I used the RANDBETWEEN function, the value in the main table may change randomly. Please pay attention to the result after the change.😋

@thisisausername , Please try for date , a measure

Second last =
var _max= maxx(allselected(Date), Date[week end Date])
return
calculate(max(Date[week end Date]), filter(allselected(Date), Date[week end Date]<_max))

or a measure like this with modification of date

Last Day Non Continuous = CALCULATE([sales],filter(ALLSELECTED('Date'),'Date'[Date] =MAXX(FILTER(ALLSELECTED('Date'),'Date'[Date]<max('Date'[Date])),'Date'[Date])))
