Luminate will not mark anything as voided when a donation is refunded. In addition, once a donation is deleted/refunded, you won't be able to access the pdf receipt. The best way to go about this if you want a receipt to show voided, you must void the donation first before you refund it.
To void a PDF receipt
1. From the navigation bar, click Setup > Receipt Manager.
2. On the Receipts list page, click Manage.
3. On the Find Receipt page, enter as much known information for the:
*First Name of constituent
*Last Name of constituent
*Receipt Number range
*Date when the receipt was issued
4. Click Search.
5. When the search results page displays, click Void from the Actions column of the receipt.
6. On the confirmation pop-up, click OK.
