Business Logic Task Handler Considerations

Business Logic Task Handlers perform business logic validation during the synchronous processing phase of the task, which occurs prior to event generation. This allows you to:

• Perform task-level validation. For example, you can add or remove members of a group based on their office location, which is specified in the user profile screen.
• Prevent a task from being submitted if the validation fails.
• Automatically transform all of the information on a task screen so that it conforms to your business policies prior to task submission.

Note: You should not implement activities that take a long time to complete in a Business Logic Task Handler. Long running activities delay the submission of the task and are not well-suited for the synchronous phase where user interaction occurs. Instead, use a workflow process, which executes during the asynchronous phase of the task.
