filter problem in a calculate function - power bi desktop
jessicaf31 - I believe your problem is context with your jourdernierjour and/or DernierJour measure. In the context of your report, it shows 3, but in the row context when your sumjoursemaine measure is calculating, DernierJour always equals the MAX of that row and thus jourdernierjour always equals the joursemaine column.
Try changing your DernierJour measure to this:
DernierJour = MAXX(ALL(Transactions),Transactions[Date])
What this does is force DernierJour to always evaluate in the context of all of the rows, which means that DerierJour will always be the MAX date within the table, which means that jourdernierjour will always be the value of the weekday of the MAX date in the table, which *should* mean that you get the right answer in your report.
I believe that you are missing a "MAX" in your FILTER. I did this measure:
Last Value = CALCULATE(SUM([Value]),FILTER(ALL(dates),[date]=MAX([Date])))
My table had a Date column and Value column, this returned the value from the last date in the table.
I am not sure how day 3 (Wednesday) is the last date in your table but I assume that's just how your data model works.
Hi !
Thanks for your answer but I also have this measure, which works.
But the other is different : it is not the max of a date that I want to filter, but only the days which are equals to my last day.
My max(date)=wednesday 24 february, so it is day 3, so I want the sum(value) for all the days 3, and I have this total in my table at the left (886K).
This formula shows me the good results :
sumjoursemaine = CALCULATE(SUM(Transactions[amount]);FILTER(ALL(Transactions);Transactions[joursemaine]=3))
But I want the last parameter : 3, to be a variable ("jourdernierjour") :
When it is a variable it doesn't work :
Thanks again !

jessicaf31 - So, I am not super familiar with your data model, but here if you can replicate this, it should get you there.
Sum of Last Value = VAR LastDayofWeek = AVERAGEX(FILTER(ALL(dates),[date]=MAX([Date])),[DayofWeek]) RETURN ( CALCULATE(SUM([Value]),FILTER(ALL(dates),[DayofWeek]=LastDayofWeek)))
So, first, figure out the MAX of the date and what the DayofWeek translates to. Assuming that all Wednesdays are "3", then taking the average will return 3 no matter how many 3's there are. My table has a Date column and a DayofWeek column calculated from the date using WEEKDAY().
Use that value to filter the rows in the table and sum the appropriate column ([Value])
Greg_Deckler Thanks again for taking time to answer and help me.
I have done the same but it is still not working.
I will describe all the steps I have done and maybe you will detect my mistake :smileyvery-happy:
1) I've created a measure DernierJour = MAX(Transactions[Date]) (DernierJour means LastDay in french :smileyhappy: )
-> it returns Wednesday 24 February 2016
2) I've created a measure jourdernierjour = WEEKDAY([DernierJour];2) (for knowing the day of the LastDay)
-> it returns 3
3) I've created a column joursemaine = WEEKDAY(Transactions[Date];2) (for knowing each weekday for each date)
3) Now I want to know the total of amount only for the days which are wednesdays (LastDay) so I've created the measure :
sumjoursemaine = CALCULATE(SUM(Transactions[amount]);FILTER(ALL(Transactions);Transactions[joursemaine]=[jourdernierjour]))
-> it returns the total of all Transactions[amount] (6,8M) without filtering on the last day (I want 886K)
Whereas when I enter this formula :
sumjoursemaine = CALCULATE(SUM(Transactions[amount]);FILTER(ALL(Transactions);Transactions[joursemaine]=3))
It works...:smileyfrustrated:
Thanks again !!
Dear Greg,
right now I'm struggling with a FILTER formula in my calculation - COUNTROWS /FILTER combination to be precise, but it doesn't work for me..
I see that your solutions are always workable and I take a dare to ask:
could you advise maybe, what do I do wrong? 🙂
thank you in advance for your help!
Katia
