Conditional Grouped SUM

[Anonymous]

Hello everyone,

I am having trouble to sum a column by ticket ID but the ticket_ID must follow a rule. 

Ticket_id	Product	Product_Type	Amount
1	A	0	10
1	B	1	5
1	C	0	10
2	A	0	10
2	C	0	10
3	B	1	5
4	B	1	5
4	C	0	10

I want to sum the total sales, of tickets that have at least a Product_type = 1.

In the example above, the result should sum the total amount of tickets 1, 3 and 4 (a total of 45) because they have at least one product of type 1.

The iteration ove the values of ID's will provide access to aggregation over ID level as will as to check conditions row by row (aggregated at ID level)

Try

Product	Total Amount =
SUMX (
    VALUES ( Data[Ticket_id] ),
    VAR Check =
        CALCULATE ( COUNTROWS ( CALCULATETABLE ( Data, Data[Product_Type] = 1 ) ) )
    RETURN
        IF ( NOT ISBLANK ( Check ), CALCULATE ( SUM ( Data[Amount] ) ) )
)

@tamerj1 perfect! 

Is it to much to ask the rational behind your code?
