To completely delete a process flow:
Right-click the process flow’s name in the Navigator pane, and then click Delete in the shortcut menu. Alternatively, you can click the process flow’s name to select it, and then click the Delete button on the toolbar or click Delete in the Navigator menu.
Note: If the delete menu options and toolbar button are not available, then you do not have the correct access permissions to delete this process flow.
A dialog displays, asking you to confirm the deletion. Click Yes and EPX deletes the process flow, provided that it does not have any dependencies.
