選択肢
- A FIXED LOD expression always follows the dimensions currently on the view.
- A table calculation operates on the raw, row-level data before aggregation, which is why its window can reach rows the view has excluded.
- A FIXED LOD expression computes at a specified granularity regardless of the dimensions on the view.
- Table calculations change the number of underlying rows in the data source.
- A table calculation operates on the aggregated results already displayed in the view.
