Tableau — Hard What is the purpose of Tableau’s RUNNING_SUM() versus a FIXED LOD cumulative total, and when would each be preferred? A RUNNING_SUM() is only available in Tableau Desktop; FIXED LOD cumulative totals are only available in Tableau Server B FIXED LOD cumulative totals are always faster than RUNNING_SUM() C RUNNING_SUM() is a table calculation that accumulates values in the order they appear in the view and is sensitive to sort order and partitioning; a FIXED LOD cumulative total is computed at the database level and is independent of the view's layout, making it more stable for embedded or exported scenarios D They produce identical results in all scenarios; the choice is purely a matter of syntax preference Show explanation
