Previous Month without filter

[legrand]

Hi,

I want to calculate the invoice count or average order value of the previous month. I got this working with either DATEADD() or PREVIOUSMONTH() but only when filtering my Power BI sheet to the current month (slicer or filter on the right hand side).

When not filtering to the current month, the number shows "Blank" when using PREVIOUSMONTH() or the count of all invoices - 1 Month when using DATEADD().

Is there a solution without having to filter the report?

Many thanks!

Hi,

I hope, posting a link like this is ok:

I created two measures:

CountLastMonth = CALCULATE(COUNT(Invoices[InvNr]);DATEADD(DateTable[Date].[Date];-1;MONTH))

CountPreviousMonth = CALCULATE(COUNT(Invoices[InvNr]);PREVIOUSMONTH(DateTable[Date].[Date]))

Many thanks!

Hey,

easiest way is just to add another measure:

CountPreviousMonthFromToday = CALCULATE([CountPreviousMonth];DateTable[Date]= Today())

 The reason is that Powerbi doesnt know for a single value what is the last passed month. Your Measure  

CountPreviousMonth = CALCULATE(COUNT(Invoices[InvNr]);PREVIOUSMONTH(DateTable[Date].[Date]))

returns a table. 

For correct function of measure 

CountPreviousMonthFromToday 

you have to extend your date table to minimun until today.

Hope it helps.

Greetings.

CountPreviousMonth = CALCULATE(COUNT(Invoices[InvNr]);PREVIOUSMONTH(DateTable[Date]))

sorry, there was a 'Date' to much 😄

find correct formula above

Hi,

thanks for the explanation. I tried your solution but the new measure still shows blank. I attached the modified PBIX.
