An expense and an expense report each have a History section, newest first. It records creation and deletion, changes to the amount, tax, currency, date, reimbursable status and reimbursement status, receipts attached or removed, and additions to or removals from a report or invoice. A report records when it is submitted, approved, rejected and marked reimbursed. Notes, tags, merchant, description and category changes are not recorded. History cannot be edited or removed.
