What Phoneboy suggested is the older but possible option to correlate FW logs into Correlated Events that the SME will show (should work).
the better R80.10 & above alternative option is to generate a 'Session' log from your FW Rulebase policy, as All Session logs are indexed & shown by the SME.
using this method, you can decide which rules specifically to log into Session logs to also get indexed & shown by the SME.
How-To: Relevant rule > Track > R-Click > More > Activate log 'per Session'.
I'd advise to disable the 1st suggested option of activating Consolidated FW Sessions, if you decide on the 2nd Rulebase 'per Session' option, as it only puts an unnecessary load on your SME server to consolidate All FW logs into correlated events.
