Measures

nuovo2 What i understand from this, you have a table which has list of all 10K memebrs and their country name. You wish to calculate total income for each country (Total Members * Income). So in this case, you can have second table where you will have country name and the income then you can link first and second table on the country name and do the calculation.

Total Income= count(members) * sum(income)

Please let us know if you wish to have something else. 

Hi nuovo2 ,

Create a measure.

income = calculate(distinctcount(member),allexcept(table,country))*number

Best Regards,

Jay

Although I am new, I have also been able to implement your solution with success. I just want to add the thousands separator plus the euro symbol.
