I am attempting to get a previous day's value. Unfortunately it doesn't seem to be working for me. Here is the formula I am using:
Previous Day Sales = CALCULATE(SUM('table'order_total]),PREVIOUSDAY('table'[ship_date]))
When I attempt to put it in the report I get (Blank). I know there is data in both the date and the order total fields for the previous day. I can get TOTALYTD and TOTALMTD to work fine using the following so the dates seem fine.
YTD Total Sales = TOTALYTD(SUM('table'[order_total]),'table'[ship_date])
Any ideas what I am doing wrong?
Hey PBIn00b -
Are you using a a calendar table? It's best practice to use a calendar table with a continuous range of dates. That way even if your business doesn't run 24/7, your date table has 1 row for EVERY day in the year(s).
Once you create a calendar table, you can create a relationship between the [CalendarDate] and 'table'[ship_date]. Power BI will take care of the rest.
My thought is that for your given filter context, there is no data with a ship date that's 1 day earlier? Can't confirm without seeing your data.
Hope this helps!
Hi ChrisHaas, thanks for your reply.
I do have a calendar table. There is a relationship between my ship date and my calendar table.
I checked the raw data and there are definitely orders from yesterday.
Also, I created another formula:
Yesterday = RELATED('ordertable'[Yesterday Sales])*'itemtable'[SKU Qty]
In the order table I set up a reference column that gives a 1 or a 0 if the date is yesterday. Then I just ask the formula to multiply that by the number of items sold. So 1 * items sold or 0 * items sold. I know there are other ways, but I wanted a very direct / basic visual of what was working or not. In this case I get data from yesterday.
I also feel like if it was a problem with my calendar table the MTD and YTD functions wouldn't work properly.
As I tested, when we directly import a date column into table visual, and include a calculated measure with PREVIOUSDAY() function, I reproduced same issue as yours. The measure return all BLANK().
However, I find if we build a date hierarchy with the date column and import the data field under hierarchy, the measure works properly.
I would recommend you sumbit this issue as potential bug on Idea: https://ideas.powerbi.com/forums/265200-power-bi. We will also report this issue internally.
@PBIn00b, with the Previous Day Sales = CALCULATE(SUM('table'order_total]),PREVIOUSDAY('ta
Or, you can have the DAX to be similar to:
CALCULATE(SUM('Purchasing PurchaseOrderDetail'[UnitPrice]),PREVIOUSDAY('Purchasing PurchaseOrderDetail'[DueDate].[Date]))
I have the same problem, while niether PREVIOUSDAY nor DATEADD functions work when I want to calculate the SUM(sessions) for a previous period. ( I need this calculation to know the growth rate for day over day
I have searched the whole powerbi community in the last three days, and much to my surprise, it is still unresolved
This is my formula : PreDaySessions = CALCULATE(SUM(Visitor[SessionS]), DATEADD(Visitor[Date].[Date], -1 , DAY))
Thanks in andvance,
