Example: If change event does not exist, drop the related task event

Scenario

Suppose you want to drop an incoming task event if the related incident change event does not exist for a third-party application.

To drop an incoming task event, perform the following steps:

  1. Define the event selection criteria.
  2. Build the policy workflow.

Actions involved

  • Unless
  • Function

To define the event selection criteria

  1. Select Configuration > Event Policies and click Create.
  2. In the Event Selection Criteria, define a condition to select events from the third-party application (with the custom event class).

The following image illustrates how the event selection criteria will look.
