To edit an Execution Set, click on the checkbox to the left of an Execution Set name and click Edit.
You can also rename an execution set without going to edit as below:
Once all your modifications are complete, click Save. You will be notified with the message below asking you to restart the scheduler in case you made modifications to the scheduling properties.
You will also notice that the row under "Last Update" column has been updated to reflect the last update done to the execution set and the name of the person who did the update will appear in "Last Updated By".
Tip
Columns on the Execution Sets page can be sorted according to your preference.
