Hi everybody !
I have a requeriment that i don't know how to achieve. Question is simple, how can I compare this year sales with exactly the same weekday sales of last year. take for instance, Today is July 1st 2016 i must compare today sales with sales on 29th June 2015 because this two days are monday of the same week.
You can think that's piece of cake, just DATEADD -365 days or DATEADD -1 year but I have to say there are some years that doesn't have 365days. For instance, this febrary have 29 days and febrary of last year have just 28, aka leap-year.
I think this could resolve my problem but actually dax doesn't accept 'week' as parameter
Ventas cliente preferente YTD:=CALCULATE( [Ventas cliente preferente] , DATEADD(Tiempo[Fecha],-52,week) )
I hope you can help me
Thanks in advance
Hi @Vvelarde, yep you're right it was 3th July 2015 I confused it with August.
About your answer, It work for this year, but what happen if the year is a leap-year? It has 366 days and a normal year has 365. It have to be dynamic or something like that. My solution have to work to infinity and beyond
A leep year still has 52 weeks so you will hit the same weekday.
But in years with 53 weeks you have to decide whether you want to go 364 days (52*7) back or (53*7) - the easy way is always to use 364 (52*7) :-)
I want to know if your Tiempo[Fecha] is continuous date or not.
If it’s continuous date you can create a measure like below:
Measure yourMeasure = CALCULATE(SUM('Tiempo'[yourColumn]),SAMEPERIODLASTYEAR('Tiempo'[Fecha]))
When you use filter on this measure, remember to remove date hierarchy, just use date.
On the other way, if your Tiempo[Fecha] is not continuous date, there is not way to come to that result you want.
One solution that came to mind is on the date (calendar) table
1. create a column WeekNo= Weeknum([Calendar[FullDate]) ( Full Date is the Date column in DD/MM/YYYY format)
2. Create a column WeekDayNo = WeekDay(Calendar([FullDate])
3. Create a column Year = Year(Calendar[FullDate])
4. Create a column DWY = ([WeekDayNo]*100+[WeekNo])*10000+[Year] . This will create numbers like 5012015, 5012016, etc. etc
depending on the Date.
5. Join your fact table to the Calendar table
6. Create a measure sya for Sales = sum(Facttable[SalesAmount])
7. Create a measure to compute the sales for same day same week last year as
SalesLYDWY = Calculate([Sales], Filter(ALL(Calendar),Calendar[DWY] = Max( Calendar[DWY]) -1 ))
8. You should now be able to view the Sales and SalesLYDWY side by side.
Sample of what I did
This should work for all years and weeks for eternity.
If this solves your requirement please accept this as a solution and also give KUDOS.
Thank you, this is great.
The only challenge I have is that my last year based on your number. 7 has one drawback.
Net Sales LY test = CALCULATE([Net Sales test];FILTER(ALL('TestDWH Date');'TestDWH Date'[DWY] = MAX('TestDWH Date'[DWY])-1))
When I have it on days, i.e. monday, tuesday etc, my "total" row in f.ex. a table only show value for sunday LY. Do I need any IF statement?
Could you please post your pbix in one drive / google drive and share the link.
Please also explain what is not working correctly.
