You do not need supporting documentation to report PDUs and renew your credential. You should complete the online Activity Reporting Forms in the appropriate amount of time and submit the Self-Directed Learning (SDL) worksheet for your reported SDL activities.
NOTE: PMI recommends you maintain a personal folder for all PDU-related documentation and keep this documentation for at least 18 months after your CCR cycle has ended. If you are randomly selected for an audit, you will need to provide this documentation.
