Manage Tasks

You can manage tasks by modifying or deleting tasks and also define task precedence.

• Modify: Use the edit icon to modify details of existing tasks of a Batch definition such as Task Description, Task Type, Batch Service URL, and Task Service URL. You can also add a new task parameter and enable or disable existing task parameters.
• Delete: Use the delete icon to remove a task from a Batch definition from the Define Task window.
• Define Task Precedence: Task Precedence specifies the execution-flow of a Batch. Task Precedence value facilitates you to determine the order in which the tasks of a Batch are executed.

For example, consider a Batch consisting of 4 tasks. The first 3 tasks do not have a precedence defined and hence will be executed simultaneously during the Batch execution. But, task 4 has a precedence value as task 1 which indicates that, task 4 is executed only after task 1 has been successfully executed.

You can set Task precedence between Tasks or define to run a Task after a set of other tasks. However, multiple tasks can be executed simultaneously; cyclical execution of tasks is not permitted. If the precedence for a task is not set, the task is executed immediately on execution of the Batch.

To define the task precedence in the Define Task window:

1. Click Menu button corresponding to the task for which you want to add a precedence task.
   The Task Precedence Mapping window is displayed.

   Note:

   The Task Precedence option is disabled if a batch has only one task associated.

   1. Select one or multiple tasks you want to execute before the current task, from the Available Tasks pane and click >. Press Ctrl key to select multiple items.
2. Click Save.
3. Click Preview to view the precedence information.
