Create a measure that calculates sum of distinct values over multiple columns in a table

[Anonymous]

My table has following structure:

In this table, if a combination of country and case have multiple weapons involved, the value shall be contained in those multiple rows(for example the 200 in row 2 and 3 here). However, I want to be able to create a table visual that gives the sum of the value per country, taking into account that only the distinct values per country and case should be summed up.

Table should look like this:

Germany 300

Belgium 200

Netherlands 100.

I'd like to use a calculated measure for this, but not sure how to code it. Can someone help me?
Regards,
Sander

Hi @Anonymous 

Try this

Totals =
SUMX (
    SUMMARIZE (
        Country,
        Country[Country],
        Country[Case],
        "Value", DISTINCT ( Country[Value] )
    ),
    [Value]
)

Replace Country by your tablename.

Hi @Anonymous ,

I forgot to add the following lines.

Now create a table visual with Country and Totals

You will get your desired result.

@Anonymous  hi can you explain the rule a bit better, why for germany is it only 300 and not 400?  there doesnt seem to be a clear rule for which row you want if there is more than one.
