Main Tasks and Subtasks
Each time you start an instance of Communications Inbound Receiver, Siebel Email Response starts one main task and five subtasks. The main task is assigned the first (lowest) task number (for example, 1318). The five subtasks are assigned the next numbers in sequence (for example, 1319, 1320, 1321, 1322, and 1323). The main task manages the subtasks and the message queue. The subtasks process inbound messages by pulling the inbound messages from the queue and passing them to the appropriate workflow.
Communications Inbound Processor has only one main task.
