You must print emails to PDF before they can be attached to a reimbursement or an advance in SAP Concur.
TIP: SAP Concur can ‘read’ your receipts using Optical Character Recognition (OCR) and create expense lines for you. You can take advantage of this feature by emailing your receipts to email@example.com. Review the ‘Using SAP Concur Optical Character Recognition to Create Expense Lines (Saves time!)’ how-to sheet to learn how!
