A code review is a mercifully simple concept to understand. Code reviews are aptly named since they are essentially the practice of having another developer on your team review your code before you merge it upstream.
A solution is a detailed description of a customer issue and the resolution of that issue. Solution managers, administrators, and users with the appropriate permissions can create, review, and categorize solutions. They can also publish solutions to the Self-Service portal and make solutions public.
The Solutions tab displays a home page that lets you quickly locate and manage solutions. If your organization uses solution categories, you can browse for and find solutions by category. You can also sort and filter solutions using standard and custom list views.
