Hi Sev,

I'm a little confused with this part:

"We created the AdminDemographics dataset via: CREATE TABLE LIKE studydataset.demographics INCLUDING ALL We registered it with LabKey as a dataset with the additional key column field set to the _key column in the dataset, marked as system managed..."

Am I correct in thinking you actually created this demographics dataset not via the UI, but directly in the database?

Regards,

Jon
