Business Rules basic questions
I am learning about Business Rules, but I have two fundamental questions. I have attached an image showing the example case & the questions:
1) There is a rule in the Inicial State that sends an email if incident.source = "Web". But if incident.source is always going to be Web, why RN isn't sending the email every time incident is updated? Or the Rule Engine only check the "Inicial State" for new incidents only? (and not updates?)
2) What is the purpose for using multiple Rule States? I thought every time an incident is updated, rule engine starts check the rules starting in Initial State....Or if there is a Second State (with transition from Initial State), now the updates of existing records will check only from Second State?
