Formatting Year and Calendar Week

[Anonymous]

Hello, 

I have a data set, which includes a column for year (2018 and 2019) and a column for calendar week (1,2,3...)

Is it possible to format the columns so that they are recognized as year and calendar week ? 

The data set is too large for a daily basis data set. 

Thanks

Anil

Try this -

Year-Wk = YEAR ( DS_1[Execution Date] ) & "-" & CONCATENATE ( IF ( WEEKNUM ( DS_1[Execution Date],21 ) < 10, "0", "" ), WEEKNUM (DS_1[Execution Date] , 21) )

I believe my problem description was not well described from my side.

When I build graphs within Powerbi, I want to calculate the sales change in % between 2019 and 2018.

Under quick measures I can select the calculation " change in comparison to previous year". Aftwerwards, I need to select the data field, based on which the previous year calculation should be made.

The problem starts after this point. I cannot select the column "Year" as a basis for the previous year calculation. It is not accepted as a date format. Since I have only the year and not the day, I could not find a way to solve this issue.

Thanks for your time

Hi,

have you a Year dimension table? Or have you just one large table?

If you have a table Calendar with the list of Year, you can create these measures:

TotalValue = SUM(Value)

TotalValue PY = CALCULATE([TotalValue], FILTER( ALL(Calendar), Calendar[Year] = MAX(Calendar[Year])-1))

Total Value YoY = TotalValue - TotalValue PY

% vs TotalVaue PY = DIVIDE(Total Value YoY,  TotalValue PY)

So you want to calculate Year-on -Year % change?

Yes, but my column  "year" is not recognized in the selection field as a valid option.

Even though I tricked and entered fake dates I recieved the following error message (sorry for german)

Netto Umsatz YoY% 2 =

IF(

    ISFILTERED('powerbi'[Datum]);

    ERROR("Quickmeasures mit Zeitintelligenz können nur über die von Power BI bereitgestellte Datumshierarchie oder die primäre Datumsspalte gruppiert oder gefiltert werden.");

    VAR __PREV_YEAR =

        CALCULATE(

            SUM('powerbi'[Netto Umsatz]);

            DATEADD('powerbi'[Datum].[Date]; -1; YEAR)

        )

    RETURN

        DIVIDE(SUM('powerbi'[Netto Umsatz]) - __PREV_YEAR; __PREV_YEAR)

)
