# Scheduling tasks

Scheduling tasks is a convenient way of continually updating the Storage Zone and associated data mart(s). For instance, you could schedule a data warehouse task to run at 4:00 pm and then schedule a data mart task to run at 5:00 pm.

Note that as Compose does not provide a task-chaining option (i.e. run another task as soon as the current task completes), it may be better to schedule tasks using an external tool that supports this capability.

You can also use the command line interface (CLI) to run a task. For details, see [Running tasks using the CLI](https://help.qlik.com/en-US/compose/December2024/Content/ComposeDWDL/Main/DL/Tasks%20and%20Workflows/run_etl_tasks_with_cli.htm).

To schedule a task:

1. Click the **Schedule** toolbar button.

2. In the **<Name> Scheduler** window, choose one of the following options from the **Run Job** drop-down list.

   * **Once** - to run the job once on a specific date and time.
   * **Every** - to run the job at set intervals.
   * **Daily** - to run the job every day at a specific time.
   * **Weekly** - to run the job on selected days at a specific time
   * **Monthly** - to run the job on the *n*th of every month at a specific time
   * **Advanced** - to use a Cron expression. For a description of allowed cron formats together with usage examples, see [Cron format and examples](https://help.qlik.com/en-US/compose/December2024/Content/ComposeDWDL/Main/DW/Cron%20Format%20and%20Examples/cron_format_and_example.htm).

3. Set the scheduling parameters according to the selected scheduling option.

4. Click **OK** to save your settings.

   The date and time the next instance is scheduled to run will appear in the **Next Instance** column.

5. To disable a scheduled job, select the task and click the **Edit Scheduling** toolbar button. Then, select the **Disable** check box in the **<Name> Scheduler** window.

6. To cancel a scheduled job for a task, select the task and click the **Edit Scheduling** toolbar button. Then, in the **<Name> Scheduler** window, click **Delete**.
