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 > --------------------------- > > Key: KYLIN-3322 > URL: https://issues.apache.org/jira/browse/KYLIN-3322 > Project: Kylin > Issue Type: Bug > Components: Measure - TopN > Reporter: liyang > Assignee: Na Zhai > Priority: Major > > Currently if user creates a measure of TopN seller by sum of price, it is > required that user also creates a measure of SUM(price).
