why can’t I set the value of a message email template with suitescript?

AI generated answer (using internal Slack threads):

In NetSuite, you cannot directly set the value of a message email template with SuiteScript. This is because email templates in NetSuite are not directly accessible or modifiable via SuiteScript. However, you can use the

render.mergeEmail

method to generate an email body based on a specific email template and a set of records. This method returns a

render.EmailMergeResult

object, which contains the generated email subject and body. You can then use these values to send an email via SuiteScript. Here's a basic example of how you might use this method:

javascript
var emailMergeResult = render.mergeEmail({
    templateId: '123',
    entity: {
        type: record.Type.CUSTOMER,
        id: '456'
    },
    recipient: {
        type: record.Type.CONTACT,
        id: '789'
    }
});

var emailSubject = emailMergeResult.subject;
var emailBody = emailMergeResult.body;

In this example,

templateId

is the internal ID of the email template,

entity

is the record that the email is about, and

recipient

is the record of the person who will receive the email. Please note that while you can use this method to generate an email body based on a template, you cannot use it to modify the template itself. The template must be created and managed in the NetSuite UI. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
