Returned value

Returns an array of two elements. First element contains an alias of selected report field. Second element contains an expression similar to those returned by the getColumnList helper class method with only difference that report settings are taken into account, such as: whether the field is countable, which operation is applied for field calculation (total, number of unique values, average, maximum, percent of column and etc.).
