complex filtering of one or more values

[mistertobi_1997]

Hi there, 

I have a question regarding a "special" filtering in Power BI. 
For example, I have a table with an ID ("A123" and "B123"), with a Country ("Germany", "France", "Spain") and values (Germany: "A123" = 100, "B123" = 200; France: "A123" = 300, "B123" = 400; Spain: "A123" = 500, "B123" = 600). 
In my table, I have a high quantity of my two IDs (e.g. 10 times "A123" and 10 times "B123", but I would like to show only the value of one ID, depending on the selected country. 

Furthermore I would like to have the possibility to filter for an ID. For example if I filter A123 and Germany, I will receive the value 100. If i filter nothing, I would like to see the sum of every value for every country, but only once. In this case, this would be 100+200+300+400+500+600= 2100 and not (100+200+300+400+500+600)*10*10.

Is there a possibility or a function to implement this idea? 

Thanks in advance
