6. Click Property in the right-side sidebar. In the Property panel, configure the task's Basic Information, Check Conditions, Scheduling Properties, Schedule Dependency, Runtime Configuration, and Resource Configuration.

   • Basic Information

     Specify basic information for the task, such as the name, owner, and description. For more information, see Configure basic task information.

   • Check Conditions

     Parameter	Description
     Check Object	Select the object to check. Only Real-time Integration Task is supported.
     Real-time Integration Task	Select the real-time integration task to check. You can select any submitted real-time integration task within the current tenant.
     Output Table	Select an output table from the selected real-time integration task to check.
     Offset Check	Select Offset from scheduled time or Specify offset. Offset from scheduled time: Enter an integer from -1440 to 1440. The default value is 3 minutes. Specify offset: Supports variables. For example, use the scheduled time variable $[yyyy-mm-dd HH:mm:ss] or a specific time such as $[yyyy-mm-dd 15:00:ss]. After configuration, click Preview to preview the parameter value.
     Stop Check Policy	At the scheduled check time, the system periodically retries based on this policy. If the condition is still not met after all retries, the check is stopped. The total check duration cannot exceed 720 minutes (12 hours). The default check interval is 3 minutes and the number of checks is 10. The minimum interval is 1 minute with a maximum of 720 checks. The maximum interval is 10 minutes with a maximum of 72 checks.

   • Scheduling Properties

     Configure scheduling properties such as the scheduling cycle and time. For more information, see Configure scheduling properties for offline tasks.

   • Schedule Dependency

     Configure upstream and downstream dependencies for the task. For more information, see Configure schedule dependencies for offline tasks.

   • Runtime Configuration

     Set a task-level runtime timeout and a retry policy for failed tasks. If not configured, the task inherits the tenant-level defaults. For more information, see Configure runtime for computing tasks.

   • Resource Configuration

     Assign a resource group to the task. The task uses resources from this group at runtime. For more information, see Configure resources for computing tasks.

7. Click the Submit icon above the editor pane to submit the current task.

8. On the Submitting Log page, review the Content to Submit and Pre-check results, and enter any remarks. For more information, see Guidelines for submitting offline computing nodes.

9. Click Confirm and Submit.

What to do next

• In Dev-Prod mode, you must publish the task to the production environment after submission. For more information, see Manage publish tasks.

• In Basic mode, the task is automatically scheduled in the production environment after submission. You can view the task in the Operation Center. For more information, see Manage integration and computing tasks, Manage one-time tasks.
