Need Assistance with Previous Week formula and the result to display on a card visualization

[solowolf]

Hello,

I am looking for some guidance on how to display a previous week's total on a card visualization. The functions I am using work very well on a table but not on a card. Any help is greatly appreciated.

<Apps PW =
VAR CurrentWeek = SELECTEDVALUE(DimDate[Week of Year])
Var CurrentYear = SELECTEDVALUE(DimDate[YearNumber])
Var MaxWeekNumber = CALCULATE(MAX(DimDate[Week of Year]), ALL(DimDate))

RETURN
SUMX(FILTER(ALL(DimDate),
    IF(CurrentWeek = 1 ,
        DimDate[Week of Year] = MaxWeekNumber && DimDate[Year] = CurrentYear - 1,
            DimDate[Week of Year] = CurrentWeek -1 && DimDate[Year] = CurrentYear)),
            [Total Applications])>

Regards, Patricio

Hi @solowolf , 

You could try to use below measure to see whether it work or not.

Measure = CALCULATE(SUM('Table'[amount]), FILTER(ALLEXCEPT('Table','Table'[name]), YEAR('Table'[date])=SELECTEDVALUE('Table 2'[year])  && WEEKNUM('Table'[date])=MAX('Table 2'[week])-1))

You could refer to my sample for details.

Hello,

Thank you so much for your help. I ended up doing a poor man's fix to this. In my date table from the source (SQL Query) I flagged the following using columns before bringing them into my model:

1. prior day =1

2. prior week =1

3. prior month = 1

4. prior year =1

...and I did the same for current, day, week, month and year.

This way I was able to write a simple DAX formula like such:

Total Last Month = CALCULATE([Total Applications], DimDate[PriorMonth] = 1)

For example, if March is your current month, then all of the dates for March will be flagged with a "1" and the previous month dates (February) will be flagged as 1.

I hope this helps someone out there that had the same issue as I did.
