You can manage existing external data flows on the External processing tab of the Data Flows landing page. For each external data flow, you can view its ID, the external data flow rule, the start and end time, the current execution stage, and the status information. You can also start, stop, or restart an external data flow, depending on its current status.
In the Action column, select whether you want to start, stop, or restart an external data flow. Different actions are available, depending on the current status.
