I am trying to create a user field, which would have a conditional value associated with it, based on a custom condition. Basically, the condition checks if field X is in a certain range, and assigns a TRUE or FALSE. Based on this, I want my field to be equal to one of the two fields in the business class (if TRUE, equal to native field, if FALSE, to the user field). I would also accept having this condition directly in a compute, or a derived field. Is there a way to do this?
