When you define a page's HelpLink and the user selects the Help link in Business Central while on that page, they will be directed to the custom link that's defined for the page. The rest of the pages in the system that are not part of your application will continue to go to the Microsoft online help website.

You can either define page-specific help links or direct all of your pages to a generic landing page. The choice is yours.

As an added bonus, you can also specify help links not only on pages, but also on report request pages and XMLports!
