I run a daily report in a workflow with a query object, and extract a report file, where I retrieve the unique opens and clicks from a set of deliveries. I am querying the 'Delivery' resource and pulling [kpis/@recipientClick] and [kpis/@recipientOpen] data, among other data. These two numbers have not increased in the last several executions. The deliveries were from a couple of months ago, and I want to continue to track these numbers. There were over a million emails delivered, so I don't believe there are no more opens and clicks, especially since they were increasing every day. I am new to Adobe Campaign, so I might be overlooking something obvious.
