Using the Job Designer, a user can configure the Tasklets that make up a Job. Initially, a Job will have no Tasklets associated with it. A Job without any Tasklets is of no value (does nothing). So to add a Tasklet to the Job, click the "Add" button. This will allow you to add a new Tasklet to the Job. Adding a new Tasklet will take you to the Tasklet Add screen where you will set the necessary Tasklet attributes and save them. This includes choosing the specific Tasklet component. Once saved, you will be returned to the Job Workflow screen.
Once the Tasklet is added, you will see the Tasklet in the Workflow screen. At this point you can add more Tasklets in the Workflow (before or after the existing Tasklet). The Tasklet can be further edited by clicking the "Edit" button. This will allow you to edit general Tasklet attributes.
If there are multiple Tasklets in the Workflow, you may change the order of execution by using the arrow buttons to move the Tasklet to the right or left, respectively, by one position at a time.
The "x" button will delete the Tasklet from the Workflow. The "I/O" button will bring up the Tasklet I/O Mapping screen to allow the user to map the outputs of one or more Tasklets to the inputs of another Tasklet that executes further down the in the Workflow chain. This is a very powerful feature, because it can allow Tasklets that have no prior knowledge of each other to communicate and pass data between each other when a job is run. So the output of one Tasklet can be passed as input to another Tasklet that runs later in the job chain.
The "?" label shows a tooltip with the Tasklet's full name, type, and description. Put your mouse over the "?" label to see this information in a tooltip.
If the Tasklet name is long, you will see the name end with the characters ".." indicating the name has been shortened for display purposes. Place the cursor over the "Edit" link and you will see a toolip showing the full length name of the Tasklet.
