To Replicate: 1. Create a patron with no overdue items and fines. 2. Enable the ILL module, and CirculateILL 3. Create a request for the patron. 4. Confirm the request 5. Click on checkout and submit. The user is then shown a checkout confirmation screen with a due date. The user then has to click on Return to request to see the original request. The request is not updated with the due date. It would be nice if the checkout automatically returned the user to the manage request screen with a checkout confirmation message and a due date added to the request details. It would also be nice if the manage ill request screen had a print option for an ILL checkout receipt (bug 40268). There is also no due date on the ILL request list, which I think libraries would really love to see so they can ensure requests are returned on time (separate bug?).
