Calculate individual month wise product sales and then divide it by number of months? Pls help me

[Anonymous]

I have the following scenario

Product        Sales           Month

A                  100              Jul

B                  200              Jul

C                  300              Jul

A                  200              Aug

B                   100             Aug

C                   50             Aug

Now, I want the following output:

First it should divide the product sales/overallproduct sales for july and then it should do the same for august

After that, i want both the result values to be divided by number of months, in this case 2 months.... as i select july and august

How to achieve this in DAX?

=> SUM ([Product] 'A') For july / SUM([Product]'A'+'B'+'C') for july

100/600

=0.16 

=>SUM ([Product] 'A') For August/ SUM([Product]'A'+'B'+'C') for August

200/350

=0.57

Finally, these two values (0.16+0.57) should be divided by 2 months

=0.16+0.57

=0.73/2

FINAL OUTPUT Needed=0.36

Pls help me guys how to achieve this

Hi  @Anonymous 

Here are the steps you can follow：

1. Create calculated table.

Table 2 =
SUMMARIZE('Table',
[Month],
"sum_A",CALCULATE(SUM('Table'[Sales]),FILTER('Table',[Product]="A")),
"sum",SUMX(FILTER('Table','Table'[Month]=EARLIER('Table'[Month])),'Table'[Sales]))

2. Create calculated column.

Divide =
DIVIDE([sum_A],[sum])

Average =
AVERAGE('Table 2'[Divide] )

3. Result.

You can downloaded PBIX file from here.

Did you try the expression I provided?  That should give you the avg pct of overall sales.

Sorry, actually I have used this logic @mahoneypat :

Average % =

AVERAGEX(VALUES('Date'[MONTH]),
IFERROR(
CALCULATE(sum(Table[SALES])
/
sumx(

ALL('TABLE'[Product]),


CALCULATE(SUMX(Table,Table[sales]))
)
,"NA"))

Please try this measure expression in a table visual with the Product column.

AvgMonthly =
AVERAGEX (
    VALUES ( Table[Month] ),
    DIVIDE (
        CALCULATE (
            SUM ( Table[Sales] )
        ),
        CALCULATE (
            SUM ( Table[Sales] ),
            ALL ( Table[Product] )
        )
    )
)

Thank you for the reply @mahoneypat 

I used this logic in the following way:

Average % =
IFERROR(
sum(Table[SALES])
/
sumx(

ALL('TABLE'[Product]),


CALCULATE(SUMX(Table,Table[sales]))
)
,"NA")

But,

When i select two months in the slicer, dax is only summing up the sales value for july and august, it is not doing the average of (summed up julay and aug sales value)

[amitchandak]

@Anonymous , Try like

divide(calculate(Sum(Table[Sales])),calculate(Sum(Table[Sales]),allexcept(Table,Table[Month])) )

[Anonymous]

The expression refers to multiple columns. Multiple columns cannot be converted to a scalar value.

Thanks for the reply @

amit!

I am getting this error when i try to do implement the logic

[manikumar34]

@Anonymous , 

Try something like this.

SUM (Table[Product]) / Calculate(SUM (Table[Product]),All(Table[Product]))
