When merging two dimensions, you might have a situation where each dimension has a different default member.

在合并两个维度时，可能出现每个维度有一个不同的默认成员的情况。

To set a default member for a dimension, add that dimension to the model, and then set the default member property.

为了设置维度的默认成员，需要将该维度添加到模块，然后设置默认成员的属性。

youdao

If the default member is not explicitly set on the virtual dimension, the default is the dimension from the first cube selected to compose the virtual cube.

如果没有在虚拟维度上显式地设置默认成员，那么默认值就是选择用于构成虚拟数据集的第一个数据集的维度。

Moving derivatives trades to clearing-houses mitigates the effect of a default of a clearing member (Lehman Brothers' cleared trades were handled smoothly in 2008, for example).
