Average Graph without the Last Month

[Young_G_Han]

  Dear Kudos

I had great help from this community and got many good Dax measures.
One of them helped me to draw the following average graph.
I could compare average sales per month year by year.
But there is one problem with this one: I have much less sales at the beginning of the month than in the previous months.

So the average becomes much less... during the beginning of a year, it affects a lot.

I want to eliminate the latest month from the calculation but I couldn't...

Can you improve the Dax measure?

The measure I used is the following.

calculate(averagex(values(date[month]), calculate([sales])), datesytd(endofyear(date[date])))

  Dear All

I successfully made a measure that will show the monthly average sales of each year, excluding the latest month.

Why do I need it?

When we are in the middle of a month, the average would be smaller compared to the previous year due to fewer sales of the current month.

So, I used a filter to exclude current month sales, the logic is simple and needs two measures.

Before to use this measure, you need to add a column in the DATE table.

YEAR&MONTH = FORMAT(DATE[DATE], "YYYYMM")

Daily Sales =
CALCULATE(SUMX(DATA, DATA[VALUE]), FILTER(DATE, DATE[YEAR&MONTH] <> FORMAT(TODAY(), "YYYYMM")))

Then

Average Month =

IF(

SELECTEDVALUE('_DATE'[YEAR&MONTH]) > FORMAT(TODAY(), "YYYYMM"), BLANK(),

CALCULATE(AVERAGEX(VALUES('_DATE'[MONTH]),

CALCULATE([Daily Sales])), DATESYTD(ENDOFYEAR('_DATE'[DATE])))

)

This will show the average sales per month in each year.

Cheers for users!

Hi @Young_G_Han ,
Here some steps that I want to share, you can check them if they suitable for your requirement.
Here is my test data:

Create a year column

Year = YEAR('Date'[DATE])

Create a average column

Average Sales by Year = 
CALCULATE(
    AVERAGE('Date'[Sales]),
    FILTER(
        ALLEXCEPT('Date','Date'[Year]),
        'Date'[DATE] < DATE(2024,2,1)
    )
)

Final outtput

  Dear v-heq-msft

Thank you for the reply.

Because my sales data has the daily sales, the measure returns different result.

I have changed your measure like below, it was working in the sample BI that you attached.

Average Sales by Year =

CALCULATE(

    AVERAGE('Date'[Sales]),

    FILTER(

        ALLEXCEPT('Date','Date'[Year]),

        'Date'[DATE] < MAX('Date'[DATE])

    )

)

But in my original BI report, it shows much smaller values since the measure calculates average daily sales in a month.

I have to make an average of monthly sales...

Do I have any chance to improve your solution???

Thanks in advance.

You add a filter that excludes the current month.

Your formula looks a bit, uhm, elaborate. Recommend you simplify it by using either CALCULATE(AVERAGE()) or AVERAGEX(), but not both together.

Dear Ibendlin

Thank you for your advice.

My problem is that my Dax ability is not good enough to edit the measures. How can I filter the measure?

My graph doesn't have any date filter, it shows all years and months.

Can you help?
