Considering the amazon_attributed_events_ tables contain ad-attributed conversions across all of your Amazon Ads media, which of the following fields would allow you to aggregate them by sponsored ads vs. Amazon DSP?

The adproducttype field is the correct choice because it directly categorizes the advertising product, such as "Sponsored Products," "Sponsored Brands," "Sponsored Display" (all part of Sponsored Ads), or "Amazon DSP." This allows for clear aggregation and differentiation between these two major advertising channels within Amazon Marketing Cloud. trafficeventtype describes the type of event (e.g., "click," "impression") and does not distinguish between ad products. supplysource indicates where the ad was shown (e.g., "Amazon owned and operated," "third-party app") but doesn't differentiate between Sponsored Ads and Amazon DSP campaigns themselves.
