Hi,Hope someone can help me out here. I uploaded a file that contains the following columns Encrypted ID and Customer Type. Encrypted client ID is something we store in an evar and was thus hoping to merge both datasets so I can see the customer type for each Encrypted ID in workspace and target. All I'm seeing is "unspecified" in workspace. I thought customer attributes worked as a mapping document but I'm not seeing anything asking for what evar I want the uploaded data to map to. Am I missing...
