Define Task Precedence

Task Precedence indicates the execution-flow of a Batch. Task Precedence value in the Task Details facilitates you to determine the order in which the specific Tasks of a Batch are executed.

For example, consider a Batch consisting of 4 Tasks. First 3 Tasks does not have a precedence defined and hence will be executed simultaneously during the Batch execution. But, Task 4 has 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 schedule a Task to run after another Task, or even define to run a Task after a set of other tasks. However, multiple tasks can be executed simultaneously and cyclical execution of tasks is not permitted. If the precedence for a Task is not set, the Task it is executed immediately on Batch execution.

To define the task precedence in the Batch Maintenance screen:

Select the button adjacent to Component ID of the required Task. The Task Precedence Mapping browser is displayed.

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

- Select the required Task from the Task List and click . You can press Ctrl key for multiple selections.

- To remove a Task, select the task from Select Tasks pane and click .
