Partial Ignore of selections in filds using Set Analysis

[Ilya_Bobrov]

Good day!
I got a problem with my expression.
When i select a month in the filter, i need to reflect data 
from the beginning of the year to the selected month inclusively. 
I used 1 in my set analysis expression,
but i need to keep the choice in the other filters(There are a lot of them) 
not used in the expression.
The expression itself:
sum({1<[SalesYear]={$(=year(now()-2))},[MonthNum]={"<=$(=num(Month(Date#(GetFieldSelections([MonthName]),'MMMM'))))"}>}[Sales]) 
Thank you in advance!

I solved this problem by changing my expression and adding to it a variable containing a list of fields

Exspression:

sum({1<SalesYear={$(=year(now()-2)-1)},[MonthNum]={"<=$(=num(Month(Date#(GetFieldSelections([MonthName]),'MMMM'))))"},$(=concat({<$Field={$(=vFieldlist)}>} '[' & $Field & ']='&'$:: '&'['&$Field&']',','))>}[Sales])
