The Name property in your screenshot is underlined and should be the unique property in your list.

Hi Francois,

The below snapshot from training material has a column labelled “Unique”. How do I see that at the mapping stage on my uploads?:

It looks like you’ve first created the dimension then tried to import data on it - to get a similar interface as the training material, you’ll have to click on Start from an import in the creation dialog.

Otherwise Pigment will create a default Name unique property.

If you’d like to keep your existing dimension, you can also edit the properties directly in the list view by going to the Configure panel, creating a ID property (unique) and editing the Name property.

ok thanks Francois
