Eksempel: Hente gyldige statusovergange
Udgivet: januar 2017
Gælder for: Dynamics 365 (online), Dynamics 365 (on-premises), Dynamics CRM 2016, Dynamics CRM Online
Denne eksempelkode er for Microsoft Dynamics 365 (online og i det lokale miljø).Hent SDK-pakken til Microsoft Dynamics CRM. Den findes på følgende placering i downloadpakken:

Krav
Du kan finde flere oplysninger om kravene til kørsel af den eksempelkode, der findes i denne SDK, under Brug eksempel- og hjælpekoden.
Demonstrerer
I dette eksempel vises, hvordan du kan hente gyldige tilstandsovergange, uanset om der er defineret brugerdefinerede tilstandsovergange for objektet.
I eksemplet udføres følgende opgaver:
Henter statusindstillinger for hændelsesobjektet
Bruger en GetValidStatusOptions-metode i til at hente gyldige statusovergange for hver statusindstilling
Viser indstillingerne for gyldig overgang i konsollen
Når statusårsagsovergange for hændelsesobjektet er konfigureret på følgende måde:
.jpeg "Eksempel på statusårsagsovergange for sag")
Gyldige tilstandsovergange er filtreret, og du kan se følgende, der repræsenterer alle de overgange, der er gyldige for hver statusindstilling.
