Una sola transacción en Amazon que incluya varios ASIN de tu marca estará representada por un solo evento de conversión dentro de cada una de las tablas amazon_atributed_events_*.

This statement is false. If a single Amazon transaction includes multiple ASINs from your brand, Amazon Marketing Cloud (AMC) will represent each ASIN as a separate conversion event within the amazonattributedeventsconversion table. This granular approach allows advertisers to attribute conversions to individual products, even when they are part of a multi-product purchase. If it were true, you would lose valuable insight into which specific products are converting within a single order.
