1.6.11 Task categories and generation timing

Tasks can be categorized as follows according to the execution timing specified when the task was submitted for execution.

Table 1‒11: Task categories
No.	Task category	Description
1	Immediate	This category of task is generated when a user submits a service for immediate execution. When the service is submitted, the JP1/AO system generates a single task and executes it immediately.
2	Scheduled	This category of task is generated when a user submits a service for execution at a specified date and time. When the service is submitted, the JP1/AO system generates a single task and executes it once at the specified time. Between generation and execution, a scheduled task stays in Waiting status.
3	Recurring	This category of task is generated when a user submits a service for execution on a recurring schedule. When the service is submitted, the JP1/AO system initially generates a single task, and executes it at the specified time. As soon as the first task is executed, JP1/AO generates the next task which it executes based on the recurring schedule. This cycle of execution and generation is repeated on an ongoing basis. Between generation and execution, a recurring task stays in Waiting status.

The following table shows the timing with which tasks are generated.

Table 1‒12: Task generation timing
No.	Service execution timing	Generated task	Task generation timing	Description
1	Immediate	Immediate execution	When the service is submitted	The task is generated when the user submits the service for execution.
2	Scheduled	Scheduled execution
3	Recurring	Recurring execution (First task)
4	Recurring	Recurring execution (Next task)	When the task is executed	JP1/AO generates the next task when it executes the first task. The cycle of executing a task and then generating the next task continues based on the recurring schedule, until canceled by a user.
