What does the 'save' button do after comments are added to a record in LeaveWeb?

The 'save' button in LeaveWeb is designed to preserve any changes made to a record, including newly added comments. When comments are inputted and the 'save' button is clicked, the system stores those comments alongside the existing data associated with that record, ensuring that the new information is not lost. This functionality is essential for maintaining an accurate history of communications and updates within the system.

Other choices do not accurately reflect the purpose of the 'save' button. Closing the application typically would not occur simply by pressing 'save'; instead, it would require a specific command to close. Deleting previous comments is also not an action facilitated by the 'save' function; it acts to keep or add information rather than remove it. Finally, the task of updating the member's leave balance involves different processing logic and would not be the direct result of saving comments. Thus, the action of saving comments is the correct understanding of the feature's purpose.
