Negative event modes in Pattern components

By default, a Pattern fires a positive event when its criteria are met, but it does not fire a negative event when the aging out of an event creates a negative condition. However, you can configure the behavior to include negative events.

When you enable negative events, the component alternates between firing positive and negative events, starting with a positive event.

You can select the mode for negative events: Immediate or Delay.

• In Immediate mode, the actions are as follows.
  • When the Pattern component fires a positive event, it retains the events that fulfilled its criteria in the customer's state history. They continue to be used in evaluating the collection of events against the pattern criteria.
  • The component fires a negative event as soon as the pattern is no longer fulfilled by collection of events being held for the customer in state history.
  • The component continues to listen for incoming events and fires a positive event when the pattern is again fulfilled.
• In Delay mode, the actions are as follows.
  • When the Pattern component fires a positive event, it drops the events that fulfilled its criteria from the customer's state history.
  • The delay period, which is specified in the duration field, begins immediately. During the delay period, the component ignores incoming events.
  • At the end of the delay period, the component fires a negative event.

When you run a workspace that includes a Pattern component configured to use the negative event mode, on the Batch Run tab of the workspace, you must set the Inactivity Mode and Inactivity Date fields.

Inactivity Mode

Set this value to On for workspaces with Forward Inactivity components.

Inactivity Date

Set this to a value greater than the latest transaction date in the last transaction file being processed.
