# Total Sales Last week Calculation DAX - Non Standard date

Hi @Greg,

Please see attached PBIX sample file regarding my query around Total Last Week calculations (Link to original query - Non-Standard Time Intelligence) .

I have a relative date filter on the visual also, to only show the last 3 weeks as this is the only way I can display the most recent data. Is there any way I can build this into the calculation without having a filter on the page?

Thanks in advance for your help

@Nurry90 Hey Mate , You can try this

Try This Dax
last 3 week sale =

``````= CALCULATE([TotalSales],

DATESINPERIOD('Date Table'[Date],

SELECTEDVALUE('Sales Info'[Wk Beginning]),-21,DAY)

)
``````

Give wk beginning date from sales table . I hope this will work for you .

Hi @samharishk,

Thanks for getting back to me. Not sure if the above is what Iām looking for. I need to get the sales amount by product for the previous week. Your formula is giving the same sales for ātotal salesā ātotal sales last weekā and " last 3 week sale" .

My formula for total sales is the total over many years(in my own dataset) as I cannot figure out how to get a dynamic total YTD calculation. I am not sure if this is why my calculations are not working out for me.

Time intelligence is not my friend, especially because I have a complex date table.

@Nurry90 .For Last week sale

last week sale =

CALCULATE([TotalSales],

DATESINPERIOD(āDate Tableā[Date],

SELECTEDVALUE(āSales Infoā[Wk Beginning]),-7,DAY)

)

You can also try these formulas ,
YTD Sales = CALCULATE ([TotalSales], DATESYTD((āDateā[Date]),ā12/31ā))
This Sales = CALCULATE ([TotalSales], DATESYTD((ENDOFYEAR(āDateā[Date])),ā12/31ā))
Last YTD Sales = CALCULATE ([TotalSales]), DATESYTD (Dateadd(āDateā[Date], -1, Year),ā12/31ā))
Last YTD complete Sales = CALCULATE ([TotalSales], DATESYTD(ENDOFYEAR(Dateadd(āDateā[Date],-1,Year)),ā12/31ā))
To get the best of the time intelligence function.
Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s.

Hi @Nurry90

Not sure I have understood your question but I provide a formula using DATESBETWEEN and you can select have far back you would like to go, 7 14 21 days.
See New Total Last Week.

Hi @Nurry90
Please ignore my last post I posted the wrong file. Sorry.

Here is the correct file Sample PBIX file EnterpriseDNA1 (1).pbix (420.4 KB)

Hi @michael66,

The calculation works fine when I use the FinYear & Week as part of the table, but once applied to a table with the products, it adds the total this week to the total last week.

See below - Product 1 Total sales for wk 19/10/2020 = \$285.10, the total the prior week 12/10/2020 = \$216.10. Once you remove the āwk Beginningā you can see that instead of the total last week showing \$216.10, it is \$501.20 (this weeks sales, and last weeks sales added together). Not sure if I am explaining this correctly, or if I am just missing something?!

Hi @Nurry90

I hope I am not misleading you or misunderstanding you.
Try using the Wk Beginning from the Date Table not the Sales Info.
Should look like this.

Cheers
Michael

Hi @michael66,

Thanks for your help here. Not sure how to explain this, sorry! I want to have a table which shows, Product, Total Sales and Total Sales Last Week, I donāt want to have the date shown, or the week number. So product 1 Total sales (this week) is \$285.10 and Total Sales Last week should show \$216.10, not \$501.20.

Similarly, product 101, total sales(this week) is \$906.39 and total sales last week is \$254.89, not \$1161.28.

There is something wrong in the below measure, that is adding the sales together.

``````total last week =
VAR _ListOfWeeks = SELECTCOLUMNS(
ADDCOLUMNS(
VALUES( 'Date Table'[FYWeeknYear]),
"@LW", CALCULATE(
MAX( 'Date Table'[FYWeeknYear] ),
FILTER(
ALL( 'Date Table' ),
'Date Table'[FYWeeknYear] < EARLIER ('Date Table'[FYWeeknYear] ) )
)
),
"Weeks", [@LW]
)
VAR _Result = SUMX(
FILTER(
ALL( 'Date Table' ),
'Date Table'[FYWeeknYear] IN _ListOfWeeks ),
[TotalSales]
)
``````

RETURN
_Result

Sorry to be bothering you! But very appreciative of the help

Thanks,
Noelle

Hi Noelle
If you donāt show the date in some form you lose Context donāt you. Date Context.
How does PBI know what is this week vs last week vs the weeks before that.
I have done another table where I have left the Wk Beginning in but through formatting you donāt see this field.
I also added a slicer so you can select the time period.Sample PBIX file EnterpriseDNA1 (1).pbix (421.9 KB)
Hope this helps, because thatās all Iāve got. I will watch and see with interest what others say.
My apologies for not solving your issue, if this does not work for you.

Hi @michael66,

Thank you for trying Not the solution I was looking for as it is still adding the previous week to the current week. Not to worry, Iāll work through what you have given me and see if I can figure it out!

Thanks again! Your help is greatly appreciated

The easiest way to tackle this is to add a new column to your date table that evaluates to either āCurrent Weekā, āLast Weekā based on the date or the relative week (as is available in the practice dataset), or blank().

Once you have this, youāll be able to use a matrix visual. The new calculated column as the columns, and the products as rows. A bit like this, where Iāve used the relative weeks on the columns:
