Get previous date values

Hi Guys,

I have a table that contains a report date and  values for that date. The dates are unique in the table.

In the visual I would like to highlight the differences of Amount 1 (Report date-Prev. Report Date) and Amount 2 (Report date-Prev. Report Date) .

I was successful in determining the previous report date, however, I can't determin the previous amounts (or at least the difference)

Actually the difference would also work.

 

Table1:

Report DateAmount1Amount2Prev. Report DatePrev. Amount1Prev. Amount2
17.03.20215015415.03.202124148
15.03.20212414814.03.202118523
14.03.20211852320.02.202133885
20.02.202133885   

Any idea how I can add this information to my table using DAX? Or a Measure?

Thanks in advance.

    Hi,

    pls see below:

    PrevAmount = 
VAR _selDate = SELECTEDVALUE(DimDate[Date])
VAR _maxDate = CALCULATE(LASTNONBLANK(DimDate[Date], CALCULATE(SUM('Table'[Amount1]))), FILTER(ALLSELECTED(DimDate), [Date] < _selDate))
RETURN
IF(NOT(ISBLANK(SUM('Table'[Amount1]))),
CALCULATE(SUM('Table'[Amount1]), FILTER(ALLSELECTED(DimDate),DimDate[Date] = _maxDate)), BLANK())

    Kind regards, Steve.

    TheHans , Try a measure like

     

    calculate(sum(Table[Amount1]), filter(allselected(Table), Table[Date] =calculate(max(Table[Date]),filter(allselected(table), [Date] <max([Date])))))

      Hi Amit,

      thanks for the quick reply. I get as a result 24 for every row.

       

      Is there a way to add new columns as in my example "Prev. Amount1" and "Prev. Amount1" which is calculated out of the existing data in the table?

       

      Basically the result of this should look like in the sample table above.
