The status of each event instance is obtained by comparing the event instances of the current run of the agent to those of the previous run. You want to specify which event statuses will cause the agent to perform the email task.
You know that for the event condition you specified, the Product name, Retailer name, and Order method data items have duplicate values in two or more event instances. However, because the Order number data item has a different value for each event instance, you choose it as the event key.
You decide that the email task you added previously should
be performed only for event instances that did not appear in the
event list the last time the agent was run.
Tip: You can add multiple tasks to an agent and use task-level filters to include only those events that satisfy a Boolean condition. See Example - Task-Level Boolean Filter.
