Continuous Week Count

Hello,

 

I am working on a project where I need to display historical data on a weekly basis (i.e. one week ago, two weeks ago, etc). The relative date slicer will not work as far as I understand because I do not want to see the data combined but rather separated. The best way I could think to do this would be to create a continuous week counter in Power BI that counts each week year over year instead of the default of 1-53 for each year, then starting back at 1 on the first week of January. I have attached a screen shot of my data table showing how when the new year begins the week counter restarts at one. Is there a formula that I can use so that the week count is continuous (instead of starting at 1 at the beginning of a new year the week count goes to 54). I have looked through various questions on the forums but have been unable to find an answer. Thank you!!!PowerBI Question.png

@AdrianHamouda,

 

Try this solution.

 

1. Create calculated table:

 

WeeksByYear = 
SUMMARIZECOLUMNS (
    DimDate[Year],
    DimDate,
    "Weeks In Year", CALCULATE ( MAX ( DimDate[Week Num of Year] ) )
)

 

2. Create calculated column in DimDate table:

 

Week Number Since Inception = 
VAR vCurrentYear = DimDate[Year]
VAR vTable =
    FILTER ( WeeksByYear, WeeksByYear[Year] < vCurrentYear )
VAR vTotalWeeksInPriorYears =
    SUMX ( vTable, WeeksByYear[Weeks In Year] )
VAR vResult =
    IF (
        ISBLANK ( vTotalWeeksInPriorYears ),
        DimDate[Week Num of Year],
        vTotalWeeksInPriorYears + DimDate[Week Num of Year]
    )
RETURN
    vResult
