Help needed with measure

[Sander1401]

Hi all,

I need help with a simple measure, but I don't get it working...
I have a dataset with Producttype - current month and Producttype - last month and numbers.
It shows the number of customers going from Producttype - lastmonth into Producttype - current month.
Now I want to built an overview which shows a measure with the aggregated numbers per Producttype - current month and the aggregated numbers per Producttype - last month.

See for an example below:

Producttype - current month	Producttype - last month	Count
A	A - B	29
A	A - C	2.882
A	A - D	1.618
A	A - D - B	3
A	A - D - C	4.843
A	A - D - C - B	3
A	D	56
A - B	A	1.142
A - B	A - C	6
A - B	A - C - B	3
A - B	A - D	6
A - B	A - D - B	41
A - B	A - D - C	6
A - B	A - D - C - B	30
A - B	D - B	1
A - C	A	2.734
A - C	A - C - B	5
A - C	A - D	42
A - C	A - D - C	769
A - C	D	3
A - C - B	A	3
A - C - B	A - B	4
A - C - B	A - C	376
A - C - B	A - D - C	4
A - C - B	A - D - C - B	13

Producttype - current month	Count - IN
A	9.434
A - B	1.235
A - C	3.553
A - C - B	400

Producttype - last month	Count - OUT
A	3.879
A - B	33
A - C	3.264
A - C - B	8

I've made a combination of calculations but now I only have the total in every row and not every row specified.

COUNT - IN = 

CALCULATE(

        SUM([COUNT]),

        'Table'[Producttype - current month] = "A",

        'Table'[Producttype - last mont] <> "A"

        )

        +          

    CALCULATE(

        SUM([COUNT]),

        'Table'[Producttype - current month] = "A - B",

        'Table'[Producttype - last mont] <> "A - B"

        )  

        +  

       etc....

Hi @Sander1401 ,

I can probably understand your idea from the formula you provided, but I don't correspond to your desired result. I don't know what you expect, such as 9.434 is calculated from the sample data.

For now, you may try this measure

COUNT - IN =
CALCULATE (
    SUM ( 'Table'[Count] ),
    FILTER (
        ALLSELECTED ( 'Table' ),
        [Producttype - current month] = MAX ( 'Table'[Producttype - current month] )
            && [Producttype - current month] <> [Producttype - last month]
    )
)

Best Regards,
