We are using the native approval process for Expense Reports. When we reject an Expense Report, there's a window showing the Rejection Reason, Employee Email, etc. Where is the rejection email being stored in NS? It's not being attached to the Communication subtab of the ERs. It shows in the Sent Email List page but it also disappears later on. We would like to be able to see the history and rejection details within NS. Same goes for approval email. It does not appear in the Communication subtab.
