ssas - How should one define a second date hierarchy in SSAS?

Question

I have a time table and a sales fact table with multiple dates (order received date, ship date).

I want to define a hierarchy on the order received date and another hierarchy on the ship date.

The cube editor in visual studio allows me to define multiple relationships on these table, but I don't see a way in the hierachy editor to define which relationship to use for the hierarchy.

Am I missing something, or am I supposed to insert the time table into the model twice, which single relationships on each?

Thanks, --sw

这不是你使用角色扮演维度的地方吗？因此，您拥有了包含所有层次结构的日期维度，然后您再次将其加入到发货日期的事实表中，现在您有了一个包含所有日期维度层次结构的“日期（发货日期）”维度。

顺便说一句，您只需创建一次 Date 维度，它每次角色扮演时都会在多维数据集中获得一个新别名。
