問題文
An author adds a custom member to the Region column of a pivot table. The new member offers no drill at all, though the ordinary regions beside it still do, and the author has to say which kind of custom member was added. Which kind is it, and what accounts for the missing drill?
選択肢
- A group, whose members come from selection steps, and steps are evaluated once the drill path of the column is discarded.
- A calculated item, which stands for a computation between members and is represented as a single member that can't be drilled.
- A group, which stands for a list of members and offers no drill because such a list carries no path to a lower level.
- A calculated item, whose aggregation is chosen after the drill path is read, so the member stays at the level it was made on.
