(from our forthcoming Do 17/215 'Kauz' book)

''After the crew returned, the pilot wrote a Gefechtsbericht (combat report), and if they claimed a victory, an Abschuβmeldung (victory report/claim form) was completed. The other crew members wrote Zeugenberichte (witness testimonies) which they signed. Their Staffelkapitän filed a Stellungnahme (statement) and this was complemented by another statement by a Stabsoffizier.''

that's six pieces of paper at least for a fighter pilot, or in the case of a Do 17 crew eighteen. The trick is to actually find surviving reports. I have seen one or two for auction, but I don't think there's many out there from the German perspective
