Hi i'm new at magento 2 and i want to change an order status of Pending to Payment Received, but i'm in homologation environment using sample data to test my store, so I still don't have a functional payment method.
Maybe the answer could be on this place that says "Automatically Invoice All Items option becomes available in the configuration". But which "configuration" ? where ?
