I have a father's entity with one child entity.

My CRM is euro based but this record needs dollar as currency. So i have a total on father entity that takes the sum of all the child's record, but the sum is taken from base field with the aggregate function, so the father's entity takes lower value than it should. I tried also to take the based field as destination field for the rolldown, but it's impossible to write some direclty.

Someone have any ideas?

(I apologize for my bad english)
