Once you are satisfied with the settings on the Basic tab, you do not need to progress through the
remaining tabs unless you want to change some of the advanced controls. As soon as you click OK on

Note

Whether you make changes to only one or to multiple tabbed pages, your changes are applied

to the database only when you click OK to close the dialog box.
