Understanding the Limitation

When working with Prompt Builder, the primary object is used to determine the available fields in the prompt. In this case, the primary object is Case, and the EmailMessage fields are related to the Case object but are not directly available in the prompt.

The root cause of this issue is the way the Prompt Builder handles related objects and fields. The EmailMessage fields are not included in the prompt by default, and there is no direct way to access them.

Including Case Emails in the Prompt

To include the last 5 emails in the prompt, you can use Flow or Apex to summarize and store the emails on the Case object. This approach allows you to create a custom field on the Case object that contains the summary of the emails.

Apex Example

// Example Apex code to summarize emails and store on Case object
List<Case> cases = [SELECT Id, Subject FROM Case];
for (Case c : cases) {
    List<EmailMessage> emails = [SELECT Subject, Body FROM EmailMessage WHERE ParentId = :c.Id ORDER BY CreatedDate DESC LIMIT 5];
    String emailSummary = '';
    for (EmailMessage email : emails) {
        emailSummary += email.Subject + ' - ' + email.Body + '
';
    }
    c.Email_Summary__c = emailSummary;
    update c;
}

Alternatively, you can use a custom component to fetch the emails and display them in the prompt.

Knowledge Article Integration

Prompt Builder can automatically use Knowledge Articles via grounding, but it is recommended to explicitly pass Knowledge summaries into the prompt for better control and customization.

Heads up: When using Knowledge Articles in prompts, make sure to configure the Knowledge settings correctly to avoid any issues.
