Calculation with multible variables in time
Hi all,
I am facing a problem in my Power BI File.
I am making a calculation based on some variable. What I am doing is comparing two numbers (current and past period) with each other to calculate the difference. To counter very small values there is a IF statement to filter these small values. My current Dimensionula is:
VAR LY_This_Period = CALCULATE(SUM('Table1'[Amount]),'Table1'[Dimension]=“Dimension”)
VAR LY_Past_Period = CALCULATE(SUM('Table1'[Amount]),PARALLELPERIOD('Calendar'[Date],-1,MONTH),'Table1'[Dimension]=“Dimension”)
VAR LY_Production_Period_DuringYear = CALCULATE(SUM('Table1'[Amount]),'Table1'[Dimension]=“Dimension”)-CALCULATE(SUM('Table1'[Amount]),PARALLELPERIOD('Calendar'[Date],-1,MONTH),'Table1'[Dimension]=“Dimension”)
RETURN
IF(AND(LY_Production_Period_DuringYear<0.049,LY_Production_Period_DuringYear>-0.049),BLANK(),
IF(OR(LY_Past_Period=0,LY_This_Period=0),BLANK(),LY_Production_Period_DuringYear))
But the problem that I face is that in the month Januari it should not take the parral period but the first date of the year. Consequential it is needed that in February the calculation only is made based on the last date of January instead of the total calculation of January.
Do you have any tips or suggestions?
Hi, Anonymous
Based on the data you provide, you can try the following methods.
Current value = SUM(Data[Value])Previous value = Var PrevDate=MAXX(FILTER(ALL('Data'[Date],Data[Year]),'Data'[Date]<SELECTEDVALUE('Data'[Date])&&[Year]=SELECTEDVALUE(Data[Year])),'Data'[Date]) Var Prevalue=CALCULATE([Current value],FILTER(ALL(Data),[Date]=PrevDate)) Return PrevalueOutcome = IF([Previous value]<>BLANK(), [Current value]-[Previous value])The result of the calculation is different from the result you expect. Consider if there is a problem with your desired result calculation?
Let me give you an example.
But in your results.
Please check if there is a problem with your result calculation in Excel, thank you.

Can you provide sample data for testing? Sensitive information can be removed in advance. What kind of expected results do you expect? You can also show it with pictures.
