Backward and Forward Looking Inactivity Components
Backward Looking Inactivity (BLI) components are used when, as the result of some present event, you want to verify that some other event did not occur within a specified previous time frame. For example, when a customer withdraws $10,000 from his account, you might want to test to see that she has not made any other withdrawals over $5,000 within the past two months.
The BLI component requires the following three parameters.
Terminating Event —the event that initiates the Backward Looking Inactivity
Inactivity Time Interval —the period of time between the occurrence of the Terminating Event and the non-occurrence of the Tracked Event
Tracked Event —the inactivity event, which may be the triggering of any of the following components.
Simple Event
Pattern
Forward Looking Inactivity
Another Backward Looking Inactivity
Container Manipulator
Action
The occurrence of the Terminating Event arms the BLI component and sets the end date for the Inactivity Time Interval. If the Tracked Event did not occur in the past time interval defined, the Backward Looking Inactivity will fire.
The Tracked Event has relevance only when the Terminating Event triggers and arms the BLI component.
