Explanation
Enabling suggested articles on new cases, enabling article submission during case close, and creating an email template to send articles as PDF attachments are recommendations that a consultant should make to assist agents with the resolution of cases using Knowledge. Suggested articles are a feature that automatically recommends relevant articles to agents based on the case information. Agents can view the suggested articles in the case feed or the knowledge sidebar, and attach them to the case or email them to the customer. Article submission during case close is a feature that allows agents to create new articles or update existing articles from the case resolution page. Agents can use this feature to capture and share their knowledge after resolving a case. An email template is a type of template that can be used to create and send emails from Salesforce. An email template can include merge fields, images, links, and other formatting options. An email template can also include a knowledge article as an attachment or a link. Agents can use this feature to send an email with the article to the customer from the case record page or the Service Console.
