A campaign that has no active targets cannot be delivered and is returned with the status "Error". This is the case if during campaign creation the automatic harvester cannot find suitable keywords, products or categories, or if no custom targets have been added when harvesting is deactivated.
To help you identify these campaigns immediately, we've introduced a new label called "No targets" that visually flags the campaign. In addition, you can use the new filter option "Campaigns without targets" to filter corresponding campaigns and manually add targets via Customize option in Campaigns table or via Amazon Advertising Console.
