Hello guys,
I have a problem that I wish to solve, if anyone could help. I tried to calculate a value of the same day, from previous month and I don't have a clue about how to do it. The comparation that I wish to show is the sales of 05-sep-2017 subtracting 05-aug-2017, in a line chart opened by day, for example. It wuold be something like this:
test = Calculate(SUM([Value]) , DATEADD([Date Event].[Day]))
-
Calculate(SUM([Value]) , DATEADD([Date Event].[Day], -1, month))
Can anybody help with a solution?
Thanks in advance
Solved! Go to Solution.
Hi @dcrios,
I created a sample table based on my assumption.
Please create measures like:
Last Month = CALCULATE ( SUM ( [Value] ), FILTER ( ALL ( 'Month-Sales' ), MONTH ( 'Month-Sales'[Date Event] ) = MONTH ( MAX ( 'Month-Sales'[Date Event] ) ) - 1 && DAY ( 'Month-Sales'[Date Event] ) = DAY ( MAX ( 'Month-Sales'[Date Event] ) ) ) ) difference = MAX('Month-Sales'[Value])-[Last Month]
Best regards,
Yuliana Gu

Great work, thanx it solves my pblm too, can u please explain in step by step
Hi,
Drag the date column to the visual filter and apply a criteria of October 5. Then write this calculated field formula
=CALCULATE(SUM([Value]),PREVIOUSMONTH(Calendar[Date]))
You should have a calendar table with running dates. There should be a relationship from the Date column of your source data table to the Date column of your calendar table.
@Ashish_Mathur my calendar table has future dates as we have set targets till 2019. This seems not to work .
