PreviousDay comparison

HI All,

 

I'm trying to make a simple report that is sorted by category, then subcategory showing sales today and sales yesterday. 

 

A slicer is used to select the date.

 

Working from a table of sales transactions and a date dimension. 

 

Can anyone hellp me with the DAX to create the "Sales Yesterday" column?

 

Many thanks,

Matt

Hi Mattperry008,

 

According to your description, you need to add a column to display yesterday's sales amount, right?

 

If that is the case, you can add a calculated column to get the sales amount of yesterday. I have tested it on my loca environment, here is sample DAX expression for you reference.
PreviousDay = DATEADD('PreviousDay'[Date],-1,DAY)
PreviousDaySales = LOOKUPVALUE('PreviousDay'[Sales],'PreviousDay'[Category],'PreviousDay'[Category],'PreviousDay'[Subcategory],'PreviousDay'[Subcategory],'PreviousDay'[Date],'PreviousDay'[PreviousDay])

Hi Everybody,

 

Still not having any luck with this one, so will try to give more info about issue. Have moved to the Contoso sample sales data from Microsoft, and still cant get it working.

 

What I need to do is display a column of sales from today and a column with sales from yesterday. 

 

The DAX I am using is Previous Quarter Sales = CALCULATE(SUM(Sales[SalesAmount]), PREVIOUSDAY(Calendar[DateKey]))

 

But when I drag the measure onto the visualisation, nothing appears for prev quarter sales.

 

Would appreciate any assistance - even pointers to good tutorials on time intelligence.

 

Many thanks,

Matt
