DAX - Sum with max and filtered data

[GustavoCamargo]

Hi everyone,

I'm struggling with DAX calculation problem as follows:

I have a table similar as mentioned below. I want to find a calculation based on summed maximumn value of 'SERVICE_QTY' times 'NET_PRICE'. I should be able to filter the data by Product Line and Model name.

PROD_ID	PRODUCT_LINE	MODEL_NAME	NET_PRICE	SERVICE_QTY	SALES
AAAA	PRODUCT A	MODEL A	259.9	2	20
AAAA	PRODUCT A	MODEL B	259.9	3	20
AAAA	PRODUCT A	MODEL C	259.9	2	20
AAAA	PRODUCT A	MODEL D	259.9	2	20
AAAA	PRODUCT B	MODEL E	259.9	2	20
AAAA	PRODUCT B	MODEL F	259.9	3	20
BBBB	PRODUCT A	MODEL A	300.5	4	15
BBBB	PRODUCT A	MODEL B	300.5	3	15
BBBB	PRODUCT A	MODEL C	300.5	1	15
BBBB	PRODUCT A	MODEL D	300.5	1	15
CCCC	PRODUCT B	MODEL E	350.2	2	10
DDDD	PRODUCT B	MODEL E	259.9	2	5
DDDD	PRODUCT B	MODEL F	259.9	3	5

I have created this measure:

QTY_PRICE = 
var MaxQty = 
    CALCULATE(max('Table'[QTY]), ALLEXCEPT('Table', 'Table'[PROD_ID], 'Table'[PRODUCT_LINE], 'Table'[MODEL_NAME]))
Return
    CALCULATE(MaxQty * MAX('Table'[NET_PRICE]), 'Table'[SALES] > 5)

With that I am able to filter the data and calculation by rows is right, however total sum showed is completly wrong...

In the example, it suppose to be 2936 instead of 1400 (image below)

Any thoughts?

Thanks in advance.

@GustavoCamargo 

1400 is calculated based on your return using the MAX price * MAX Qty.

It is a very common question that why the measure total is not the sum of the previous rows on the table visual. I really suggest you to take a look at the 2 short blogs.
