I am using render.mergeEmail, with a vendor bill Id, In the template there is a {transactionnumber} field, it is not filling that info in template.

AI generated answer (using internal Slack threads):

Based on the conversations, it seems like the issue you're facing is related to the way you're using the

render.mergeEmail

function. When using this function, you need to pass the transaction id as a parameter. This is done by adding

transactionId: id

to the function call. Here is an example:

javascript
var mergeResult = render.mergeEmail({
    templateId: 12,
    transactionId: journalEntry.id
});

In your case, you should replace

journalEntry.id

with the id of the vendor bill you're working with. Also, it's important to note that the

relatedRecords

parameter in the

email.send

function is used to attach the email to the record so you can see it in the record's emails. It doesn't affect the email template merge using

render.mergeEmail

. As for the

{transactionnumber}

field in your template, it should be replaced with the actual field name from the vendor bill record. For example, if the field name is

tranid

, you should use

${transaction.tranid}

in your template. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
