Subject Segment columns and dimension columns
Date Wed, 19 Sep 2018 07:13:39 GMT

I am having a question regarding two types of columns mentioned above. If I am using a column
as a segment column, such as DAY, and it’s required as the filter in queries, should I also
put it in the dimension columns, or is it redundant to do so? If it’s included in the dimension
columns, does it mean the records from different segments can’t be merged since the DAY
field is different (DAY=20180918, DAY=20180919)?

Thanks for your help!

Best, Feng.
