Any information you enter during the registration steps will be saved once you click the <Save> button on the portal screen. For example, if you are on Business Capabilities, for example, by clicking on the navigation buttons on the bottom of the screen to the previous screen (e.g., <Prev: General Overview>) or to the next screen <Next: Diversity>), you will also save any information you entered.
Note: While the information is saved, it has not been verified and you will still need to verify it when you return, especially if you received any system-generated error messages. Also, you can logout and return at a later date to finish registration.
