You have to create a Custom Type for that field "Risk Name In WSReputation" and then you can use it in rule creation.
System Configuration -> Custom Types -> Add
Make sure not to use the same custom field on two fields in the same rule. So pick the events field of "Risk Name In WSReputation" with extra care.
Where can we create a new Custom Type. I dont see any field in System Properties. There is one Custom Settings tab, but there is no option to add any fields.Can you please help. We are using 9.6.0.
You are most probably logged in with an external account.
Login with NGCP username and you should see it right below Custom Settings.
