Hi Shuai,
It is a display issue I think, you don't need to care about it much. If brings confusion, we can refine it.&nbsp;

Hi Shuai,

Sometimes, it can be another fact table (such as a very big user table, joining with a transaction table), "dimension table" is not accurate as well. I think that's why the original developer implemented it with this logic.

Hi Shuai,

Sometimes, it can be another fact table (such as a very big user table,
joining with a transaction table), "dimension table" is not accurate as
well. I think that's why the original developer implemented it with this
logic.
