Get previous date values

[TheHans]

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 Date	Amount1	Amount2	Prev. Report Date	Prev. Amount1	Prev. Amount2
17.03.2021	50	154	15.03.2021	24	148
15.03.2021	24	148	14.03.2021	185	23
14.03.2021	185	23	20.02.2021	33	885
20.02.2021	33	885

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.
