SQWL Query to select SourcePort and DestinationPort

Hello,

I am trying to run this query in SWQL:

SELECT TotalBytes, TotalPackets, SourceIPSort, DestIPSort, Protocol, ProtocolName, SourcePortName, DestPortName, SourcePort, DestPort, SourceAppID, DestAppID, StartTime, SourceSinglePort, DestSinglePort, DisplayName, Description, InstanceType, Uri, InstanceSiteId

FROM Orion.NetFlow.ConversationsDetailReport

(Filter='NSF:C:10000000001-255249000001;TD:2016-11-22T00:00:00~2017-11-23T00:00:00,1,True,True')

However, there seem to be no results.

Is this table populated at all? And is it possible to upload data onto it?

Your help would be really appreciated.

Paolo
