Veelgestelde vragen over automatisch laden met bedrijfsgegevens
Notitie
Vanaf november 2020:
- Common Data Service heet voortaan Microsoft Dataverse. Zie Power Automate-blog voor meer informatie.
- Een deel van de terminologie voor Microsoft Dataverse is bijgewerkt. Entiteit is nu bijvoorbeeld tabel en veld is nu kolom. Zie Terminologiewijzigingen voor meer informatie.
Dit onderwerp wordt binnenkort bijgewerkt om de meest recente terminologie weer te geven.
Waarom heb ik automatisch laden nodig?
U hebt mogelijk een bestaand Dataverse- of andere Dynamics 365 app-exemplaar met bedrijfsgegevens en wilt wilt hiervoor een verbinding voor twee keer wegschrijven inschakelen. In dat geval moet u gegevens uit Dataverse of andere Dynamics 365-apps automatisch laden met bedrijfsgegevens alvorens verbinding voor twee keer wegschrijven in te schakelen.
Wanneer moet ik automatisch laden gebruiken?
Gebruik automatisch laden voordat u tabeltoewijzingen voor twee keer wegschrijven inschakelt (tijdens stap 5).
Als u de verbinding voor twee keer wegschrijven tussen exemplaren van uw Finance and Operations-app en de Dataverse- of andere Dynamics 365-app wilt instellen, meldt u zich als beheerder aan bij de Finance and Operations-app.
Ga naar de module Gegevensbeheer en klik op de knop Twee keer wegschrijven. Hierdoor wordt de Gegevensintegrator gestart.
Maak de verbinding voor twee keer wegschrijven voor een of meer bedrijven.
Schakel de tabeltoewijzing Cdm_companies in. Hiermee worden bedrijven vanuit de Finance and Operations-app gesynchroniseerd naar Dataverse.
Voer de voorbeeldcode voor automatisch laden uit op het exemplaar van de Dataverse- of andere Dynamics 365-app.
Wanneer het automatisch laden is voltooid en het systeem gereed is voor de live synchronisatie, schakelt u de tabeltoewijzingen in.
Als u de tabeltoewijzingen inschakelt, wordt de initiële gegevenssynchronisatie geactiveerd voor de ingeschakelde tabeltoewijzingen. De gegevens die overeenkomen met de bedrijven die zijn gekozen op de verbinding voor twee keer wegschrijven worden gesynchroniseerd tussen de Finance and Operations-app en Dataverse.
Hoe gebruik ik de voorbeeldcode?
De voorbeeldcode is een C#-toepassing die u in Visual Studio kunt laden. Het gebruikt afhankelijkheden van het NuGet-pakket in de SDK van Dataverse, die u kunt vernieuwen via standaard Visual Studio-hulpprogramma's.
Nadat u de oplossing hebt uitgepakt en geopend in Visual Studio en de NuGet-pakketten hebt hersteld, zoekt u naar TODO in de code. Elke beslissing die u moet nemen over de manier waarop u de bedrijfsgegevens automatisch wilt laden, wordt aangegeven door een TODO met voorbeeldcode voor een canonieke implementatie.
De voorbeeldcode toont slechts één van de vele manieren waarop u entiteitsrijen per bedrijf kunt categoriseren. Door de logica in de sectie TODO te wijzigen, kunt u uw aangepaste categorisatie maken.
Wat kan ik verwachten?
Standaard kunt u met de voorbeeldtoepassing een woordenboek met codetoewijzingen van bedrijfseenheid naar bedrijf opgeven. Elke entiteit die u automatisch laadt met een veld OwningBusinessUnit, wordt automatisch ingesteld voor gebruik van het opgegeven bedrijf. Elke entiteit zonder een veld OwningBusinessUnit, zoals product, stelt het bedrijf in op basis van de toewijzing met een lege waarde voor bedrijfseenheid.
De consoletoepassing verwacht één parameter. Dit kan –simulate of –apply zijn. Als u de opdrachtregelparameter –simulate gebruikt, worden er geen gegevens bijgewerkt. Alleen simulation_.csv-bestanden worden in dezelfde map gegenereerd als het hulpprogramma, één voor elke entiteit die zou zijn bijgewerkt. U kunt deze bestanden iteratief controleren tijdens het werken om te controleren of de bedrijfswaarden volgens verwachting worden bijgewerkt door de code.
Wanneer u klaar bent met de gesimuleerde updates, gebruikt u de parameter –apply. Hiermee worden alle rijen bijgewerkt die op dit moment een onjuiste bedrijfswaarde hebben, in batches van 1000 rijen tegelijk (standaard). De code is idempotent zoals opgegeven, wat betekent dat u deze opnieuw kunt uitvoeren en dat alleen de onjuist toegewezen bedrijven worden bijgewerkt. Wanneer de code wordt uitgevoerd met –apply, worden CSV-bestanden van de aangebrachte wijzigingen uitgevoerd door de code met de naam applied_.csv.
