to make things complicated our devs use the same terminology for dates (different dates) across tables. i.e. both properties and other objects have a "createdAt" date attached, but the createdAt dates are unique to the table in which they sit.

Hi Hesseltje, thank you for your question. The URN in the date dataset refers to the date dimension template you are using and it generally doesn’t need to be modified. See for example: Manage Custom Date Dimensions. For your use case, I would recommend using the Date Dimension Loader.

Thank you Moises! I'll attempt this now.
