Hi Marc, Thanks very much for reporting. Your previous example then shows that *CategoryL5* really behaves like a segment. If it's a key column, even if you don't request for it, there should be two rows returned. I'll talk with engineering to see how we fix this.
As for your other questions: > 1) How do I know what are the "key fields" in a report? Unfortunately, it's not quite obvious from the field itself. But we try to document it in the summary description in the beginning of each report type page. 2) You wrote "Have a look at OfferId and CategoryL5, you can tell that > those two rows are different" - you mean combined, correct? Because the > OfferId here is the same Yes, combined. It's like you have a composite key in relational databases. Only one key can't tell uniqueness of a row. We have to use them together to tell uniqueness. I find this confusing and would expect to get just one row with the product > and with CategoryL5 set to the most recent value for that product... I've passed this feedback to engineering too. For now, would using date range help you? Or does it always return two rows for any kinds of date ranges?
