Redwood OM pages without PDH implementation? Item setup Redwood enabled can it be done without PDH?

To enable Redwood for Order management, one of the crucial step is to complete Item setup, Configuring Index from Tasks available in PIM task pane. I am experiencing that the tasks are not available in that pane. Can anyone please help on how to enable those tasks.
