Adding pre- and post-activities to data flows
You can specify the activities that are executed before and after a data flow run. Use them to prepare your data flow run and perform certain actions when the run ends.
Pre-activities run before assignments are created.
Post-activities start at the end of the data flow regardless of whether the run finishes or fails.
Both pre- and post-activities run only once and are associated with the data flow run.
