When a concurrent workflow does not have unique instance names or when you do not want to run the configured instances, you can start a workflow with the Workflow Designer. If you start the concurrent workflow with the Start Workflow option, the Integration Service runs the workflow with the attributes and variables you define on the workflow Properties and Variables tabs. The Integration Service does not run any of the configured workflow instances.
To start one concurrent workflow instance:
Open the folder containing the workflow.
From the Navigator, select the workflow that you want to start.
Right-click the workflow in the Navigator and choose Start Workflow.
The Integration Service runs one instance of the workflow with the attributes from the workflow Properties and Variables tabs.
