Additional information

An extra document is attached to the email, which contains the original invoice. In the expression of this new part, the existing document is read from the document store using the keywords. It is therefore very important to fill the keywords with proper values.

In the expression, you are using the dom.existing.document.add() function to retrieve the existing invoice document from the document store and add this to your email message.

You are also using the dom.add.part() function to add an overlay to the document.

For the syntax of these functions, see Adding existing documents from the DOM document store.
