But in the London version and higher, it is behaving differently. Even though the 'Created' field in 'Additional group by' is added, it does not appear in the 'Stack by' list. Steps To Reproduce Observation in Istanbul: Go to create ReportsGive the Table name 'Incident'Type - BarGroup by - CategoryAdditional Group by - Priority and createdAggregation - countselect stacked Based on the above observation, we can see that the in Istanbul release, 'Stacked by' has 'Created' as an option when 'Created' is added to 'Additional group by'. Observation in London and higher: Go to create ReportsGive the Table name 'Incident'Type - BarGroup by - CategoryAdditional Group by - Priority and createdAggregation - countselect stacked Based on the above observation, we can see that the in London release, 'Stacked by' doesn't have 'Created' as an option even when 'Created' is added to 'Additional group by'. In the versions London and higher, the available 'Stack by' fields is limited to catalog variables, reference fields, lists, and boolean values. Date/time, integer, long, string, list, and text fields cannot be used as stacked fields. Hence the 'Created' field does not appear in 'Stacked by' in the London version, whereas it appears in 'Stacked by' in the Istanbul version. Affected Versions London and higher versions Additional Information In Istanbul, all fields are supported in 'Stacked by'. In London and higher versions, only catalog variables, reference fields, lists, and boolean values can be used in 'Stacked by'. Date/time, integer, long, string, list, and text fields cannot be used as 'Stacked by' fields.
