Exemple : Calculer le plug-in Tarifs
Date de publication : janvier 2017
S’applique à : Dynamics 365 (online), Dynamics 365 (on-premises), Dynamics CRM 2016, Dynamics CRM Online
Cet exemple de code est pour Microsoft Dynamics 365 (Online et local).Téléchargez le package Kit de développement logiciel (SDK) de Microsoft Dynamics CRM. Il se trouve à l'emplacement suivant dans le package de téléchargement :
SampleCode\CS\BusinessDataModel\ProductCatalog\CustomPricePlug-in\CalculatePricePlugin.cs
Configuration requise
Assurez-vous de ce qui suit :
Définissez la valeur de l'attribut Organization.OOBPriceCalculationEnabled sur 0 (faux).
Inscrivez le plug-in dans le message CalculatePrice, la phase d'événement Opération postérieure, et le mode d'exécution Synchrone. Pour plus d'informations, voir Inscrire et déployer des plug-ins.
Démontre
Cet exemple indique comment écrire un plug-in qui calcule la tarification des opportunités, des devis, des commandes et des factures, selon votre code personnalisé. Les remises et les taxes sont calculées selon le montant total de tous les articles de la ligne de produit d'une opportunité, d'un devis, d'une commande ou d'une facture :
Remise : Si le montant total est supérieur à 1 000 et inférieur à 5 000, la remise est de 5 % ; si le montant total est égal à 5 000 ou supérieur, la remise est de 10 %.
Taxes : Les taxes sont appliquées sur le montant appliqué une fois la remise déduite (montant total moins la remise). Si le montant appliqué est inférieur à 5 000, les taxes sont égales à 10 % ; sinon, les taxes sont de 8 %.
