Dieser Beispielcode ist für Dynamics 365 Sales. Informationen zum Herunterladen des Beispiels finden Sie unter "Arbeiten mit benutzerdefiniertem Preis-Plug-In".
Voraussetzungen
Um das Beispielprojekt herunterzuladen und die NuGet-Pakete wiederherzustellen, die im Beispielprojekt verwendet werden, ist eine Internetverbindung erforderlich.
Anforderungen
Stellen Sie sicher, dass die folgenden Anforderungen erfüllt sind:
Setzen Sie den Wert der
Organization.OOBPriceCalculationEnabled-Spalte auf0(falsch).Registrieren Sie das Plug-in in der CalculatePrice-Nachricht, Post-Operation-Ereignisphase und Synchron-Ausführungsmodus. Weitere Informationen finden Sie unter Registrieren eines Plug-ins.
Veranschaulichung
Dieses Beispiel zeigt, wie ein Plug-In geschrieben wird, das die Preisberechnung der Verkaufschancen, Angebote, Aufträge und Rechnungen basierend auf Ihrem benutzerdefinierten Code berechnet. Die Steuern und Rabatte werden basierend auf dem Gesamtbetrag aller Produktlinieelemente in einer Verkaufschance, einem Angebot, einem Auftrag oder einer Rechnung berechnet:
Rabatt: Wenn der Gesamtbetrag größer als 1.000 und weniger als 5.000 ist, beträgt der Rabatt 5%. Wenn der Gesamtbetrag 5.000 oder höher ist, beträgt der Rabatt 10%.
Steuer: Steuer ist auf den Betrag angewendet, der effektiv ist, nachdem der Rabatt angewendet wird (Gesamtbetrag miuns Rabatt). Wenn der effektive Betrag kleiner als 5.000 ist, beträgt die Steuer 10%. Andernfalls beträgt die Steuer 8%.
Weitere Informationen finden Sie unter Benutzerdefinierte Preise für Produkte verwenden.
