Hi ​@tjain02 ,

The second part will be mapped to the “Local” item in the Conversion dimension because of this piece of formula: 
 

rby sum : Conversion."Local"]

Hope this helps, 

Hey ​@Stef ,

My confusion is regarding the ‘+” operator. Wouldn’t that be used for summing values? Here in this context it seems it is being used to separate values based of different list items

Hi ​@tjain02 ,

I see. Imagine you would have three separate metrics:

Metric A:
'FX_01_Calc_FX Rates Staging'iADD constant: Version] o by sum  : Conversion."Group"]

Metric B:
1rADD constant: Month, Currency, Version] iby sum : Conversion."Local"]

Metric C:

(A+B) Afilter:'Set_Filter_Version Window']

In metric C you would get the same result as in your combined formula. The + operator indeed sums the values but because they are both allocated by another item of the Conversion dimension you would never see the sum unless you’re looking at “Local” + “Group” (which does not make sense). 

Hope this helps,

Hey ​@Stef , thanks for explaining it in this way. Makes sense now.
