Set up PO

[turbo]

Hi all,
In the PO setup step:
Step 15: Set Up Oracle Workflow is required. But I don't install Oracle Workflow. So Do I need to setup these step in Oracle Workflow:?
? Step 1: Partitioning Workflow Tables
? Step 2: Setting Global User Preferences
? Step 3: Setting Up an Oracle Workflow Directory Service
? Step 4: Setting Up Additional Languages
? Step 5: Setting Up Background Workflow Engines
? Step 6: Implementing Notification Mailers
? Step 7: Modifying Your Message Templates
? Step 8: Adding Worklist Functions to User Responsibilities
? Step 9: Setting the WF: Notification Reassign Mode Profile Option
? Step 10: Setting Up Notification Handling Options
? Step 11: Setting Up for Electronic Signatures
? Step 12: Customizing the Logo on Oracle Workflow's Web Pages
? Step 13: Adding Custom Icons to Oracle Workflow
? Step 14: Setting Up the Business Event System

Thanks!
