Adding pre- and post- activities to data flows


Only available versions of this content are shown in the dropdown

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, fails, or stops. Both pre- and post-activities run only once and are associated with the data flow run.

  1. Create an instance of the Activity rule.

  2. On the Pages & Classes tab, specify the following details:

    • Page name: For example, RunOptions
    • Class: For example, Data-Decision-DDF-RunOptions
