In an SSRS report I've got a row group for which a handful of variables are defined; i.e. they are defined at the group not the report level. Some of the variables are a function of the other variables.
Within the context of a row is the value for the variable at that row re-evaluated each time the variable is referenced (either to display in a tablix or as part of a another variable's calculation) or are the values evaluated once for each row and cached for subsequent display and calculations?
