Szenario

Um sicherzustellen, dass den Kunden nur die Serviceleistungen in Rechnung gestellt werden, die sie erhalten haben, möchte der Programm-Manager, dass die Anwendung eine Liste der vom Dienstleister erbrachten Leistungen anzeigt. In der Liste sollen die Bezeichnungen und die Anzahl der erbrachten Leistungen, der Einzelpreis und die Gesamtkosten jeder Leistung und die Gesamtkosten aller erbrachten Leistungen angezeigt werden. Konfigurieren Sie im Ablauf „Perform service“ die Datentransformation „CopySelectedServices“, um die erbrachten Leistungen von einem Service-Case in einen Assistance Request-Case zu kopieren.

Die folgende Abbildung zeigt die Beziehung der Seitenliste „Selected Services“ im Case-Typ „Assistance Request“ und der Seitenliste „Services“ im Case-Typ „Service“ zum Datentyp „Services offered“.
