Denne eksempelkode er til Dynamics 365 Sales. Download eksemplet: Arbejd med plug-in til brugerdefineret pris.
Forudsætninger
Der kræves internetforbindelse for at hente eksempelprojektet og gendanne de NuGet-pakker, der bruges i eksempelprojektet.
Krav
Sørg for at gøre følgende:
Indstil værdien til
Organization.OOBPriceCalculationEnabledkolonne til0(falsk).Registrer plug-in'en på meddelelsen CalculatePrice, hændelsesfasen efter handlingen og synkron udførelsestilstand. Du kan få flere oplysninger under Registrer en plug-in.
Demonstrerer
Dette eksempel viser, hvordan du skriver en plug-in, der beregner prisfastsættelsen for salgsmuligheder, tilbud, ordrer og fakturaer baseret på din brugerdefinerede kode. Rabatterne og momsen beregnes på baggrund af det samlede beløb for alle produktlinjeelementer i en salgsmulighed, et tilbud, en ordre eller en faktura:
Rabat: Hvis det samlede beløb er større end 1000 og mindre end 5000, er rabatten 5%; hvis det samlede beløb er 5000 eller højere, er rabatten 10%.
Moms: Der anvendes moms på det beløb, der træder i kraft, når rabatten er anvendt (samlet beløb minus rabat). Hvis det effektive beløb er mindre end 5000, er skatten 10%; ellers er momsen 8%.
