Adding conditional logic to the instructions and adding a formula block to the macro are solutions that a consultant can suggest to meet the agent's requirements of sending email to customers prior to violating an SLA based on three different SLA levels using macros. These solutions can help create macros that perform different actions based on different criteria, such as the SLA level of the case. For example:
* Adding conditional logic to the instructions is a solution that involves using IF and ELSE statements to control when to execute certain actions in a macro. Conditional logic can be used to create a macro that checks the SLA level of the case and sends an appropriate email template based on the SLA level. For example, if the SLA level is Gold, send an email template with a high priority message; else if the SLA level is Silver, send an email template with a medium priority message; else, send an email template with a low priority message.
* Adding a formula block to the macro is a solution that involves using formulas to calculate values or perform logic in a macro. Formula blocks can be used to create a macro that calculates the time remaining before the SLA violation and inserts it into the email body using quick text. For example, use a formula block to subtract the current date and time from the SLA violation date and time, and format the result as hours and minutes. Then use quick text to insert the result into the email body.

To comply with global data protection and privacy regulations, the consultant should recommend systematically searching for and removing all customer personal data from production and sandbox environments. This includes data in records and unindexed free text fields, followed by refreshing sandboxes to eliminate any residual data, ensuring compliance and safeguarding customer privacy.

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.
