Because each configuration parameter is opened up for editing one at a time, you can Update your changes without advancing to the next step in the market certification case. Use the Update link to save the changes you have made in the configuration parameter. Your changes will be validated when you click Save at the bottom of the page.

This will not exit the update mode for this configuration parameter; if you wish to edit a different parameter, click the Edit link for that parameter, otherwise click ">> Save & Next" at the bottom of the page.
