Alert is created even though no event rule is applied

[masahironaka]

We use event management.
We manually triggered the event in a condition where no alert was created to verify.
However, the alert is created and the following message is displayed

message:Event rules are not applied.

so an alert is being created even though there is no event rule applied.

【question】
①Please tell me why an alert is created even though the applicable event rule does not occur.
②Is it possible that the alert is created because of event rule or business rule?

thank you.

"Created new simulated alert with state Open from event: "
