KPI Visual - Last week comparison

[Anonymous]

Hello, im very new to power bi, and so im, still, a little lost week dax.

I want to make a visual that compares the last week, something like this:

which the goal should be the value of last week.

I tried to made a measure like this:

Realizadas Last Week = CALCULATE(sum(ft_dados_base[realizadas]);filter(ft_dados_base;ft_dados_base[semana_ref]="Semana W-1"))

But shows me like this:

the original idea would be to show,  in the column "Realizadas LastW" in the W51, the value of the W50, so in the KPI visual the goal would be of the W50.

I tried to search for an answer but couldnt find one.

what can i do to made this work?

thank you

Hi @Anonymous

It would probably be easier to have just the week numbers instead of the 'W' plus the number. If you have the weeks in the rows of the matrix as you show, you can use a measure like:

Measure=
VAR  _CurrentWeek = SELECTEDVALUE(Table1[Week])
VAR _PreviousWeek=  "W" & VALUE(MID(_CurrentWeek, 2, LEN(_CurrentWeek)-1))-1
RETURN
CALCULATE(SUM(Table1[realizadas]), Table1[Week]=_PreviousWeek)

Hello @AlB i have a column with the yearweek too, the W51 is represented with 201851.

But it worked 😄

Shows the goal as a WoW percentage

Thank you so much for the help.

Cool 

If it's what you were looking for, please accept the answer as solution so that it's visible for others as well.

Done 😉

Just, for my knowledge.

What would be the measure if i had the week without the W?

Would be the same but without the mid function?

Yes, if you have a number you can just subtract the 1 directly to get the previous week. You don't need all the hassle of converting forth and back between text and number.
