Define Task Precedence
Task Precedence indicates the execution-flow of a batch. Task Precedence Value helps to determine the order in which the specific tasks of a batch are executed.
For example, consider a Batch consisting of four tasks. The first three tasks
lack define precedence and hence will be executed simultaneously during batch
execution. However, Task 4 has a precedence value as Task 1, indicating that Task 4 is
executed only after the successful completion of Task 1.
You can set Task Precedence between Tasks or define to run a Task
after a set of other tasks. While, multiple tasks can be executed simultaneously,
cyclical execution is not permitted. Tasks without defined precedence execute
immediately upon Batch Execution.
Note:
The Task Precedence option is disabled if a batch has only one associated task.To define task precedence:
- Click Add or Remove Precedence corresponding to the task
requiring precedence, to access the Precedence Mapping
list.
- Click Save to update Task Precedence in the batches.
- Click Preview to view the precedence information.
