Vsevolod Ostapenko commented on KYLIN-3322:
-------------------------------------------
It's also reported as KYLIN-3687. It's good to have documentation updated, but
it's better to prevent creation of the incomplete TopN cube definitions through
the UI and via API calls.
> TopN requires a SUM to work
