A workflow is combination of multiple tasks connected with links that trigger in a proper sequence to execute a process. Every workflow contains a start task along with other tasks. When you execute the workflow, you actually trigger the Start task, which in turn triggers other tasks that are connected in the flow.
The following figure shows you a sample workflow:
Informatica PowerCenter provides options to create Workflow manually and automatically; these options are discussed in the upcoming sections.
To create a workflow manually, perform the following steps:
wf_WORKFLOWNAME
. Then, and click on OK. We are using wf_PASS_THROUGH
as the workflow name for our reference.A start symbol appears on the screen in Workflow Manager. Also, the wf_PASS_THROUGH
workflow appears under the navigator, as shown in the following screenshot:
With this, we have learned how to add the start task as a first step to creating the workflow. In the next section, we will create the workflow directly from designer screen.
Informatica PowerCenter provides a utility to create the workflow directly from the designer client tool. This feature lets you create a workflow for a particular mapping from designer screen. To create a workflow from designer screen, perform the following steps:
wf_PASS_THROUGH_EMPLOYEE
and s_m_PASS_THROUGH_EMPLOYEE
as our workflow and session task name. Now, click on Next.PowerCenter will generate a workflow with a start task and session task in Workflow Manager. Open the Workflow Manager screen to check the workflow. If you are already connected to Workflow Manager, disconnect the repository and connect again to see the workflow under the navigator.
