Exemple : Module de calcul des prix

Cet exemple de code s’applique à Dynamics 365 Sales. Pour télécharger l’exemple, consultez Utiliser le plug-in de prix personnalisé.

Prerequisites

Une connexion Internet est requise pour télécharger l’exemple de projet et restaurer les packages NuGet utilisés dans l’exemple de projet.

Configuration requise

Assurez-vous que les exigences suivantes sont satisfaites :

  • Définissez la valeur de la colonne Organization.OOBPriceCalculationEnabled sur 0 (false).

  • Inscrivez le plug-in dans le message CalculatePrice, l'étape d'événement Post-opération, et le mode d'exécution Synchrone. Pour plus d’informations, consultez Inscrire et déployer un plug-in.

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 de 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 effectif est inférieur à 5 000, l’impôt est de 10%. Sinon, l’impôt est de 8%.
