Need Help identifying what this is and how to recreate it.

[OhLookAnError]

I am moving pages from one report to another and I need to recreate this date hierarchy but this field has an emblem next to it I've never seen so I'm not sure what it is or how to recreate it. Any help would be greatly appreciated!

@OhLookAnError , the first one has become a key column because you have marked the "date" table as Date Table.

You can create a new column

Date1 = [Date]

that can give you a hierarchy if auto-time intelligence

These are the reasons Date Hierarchy can be missing
