In "travel expenses" there is an expense named "Piccole spese per pernottamento (tassa di soggiorno)". In the past was possible to choice this expense without a receipt for the amount of 9.00 Euro. It's still possible?
This question is for your company's set-up. Unfortunately, we do not have to that. I would recommend reaching out to your Concur Administrator. If you do not know who that is, the best places to start would be your supervisor or finance. They should be able to direct you to the person at your company responsible for the administration of Concur.
@ddedomi I looked at the configuration of your site and expenses that are paid for out of pocket will require a receipt, except some expense types. The Piccole spese per pernottamento (tassa di soggiorno) expense type does fall into requiring a receipt.
