Tilpasse prosedyreplaner med Apex Hooks

For å støtte unike prisscenarier legger du til tilpasset Apex i prisprosedyreplanene. Du kan bruke Apex til å bruke tilpasset forretningslogikk som endrer priskonteksten etter at en tilbudslinje har blitt konfigurert. Bruk en Apex prehook til å justere pris basert på produktattributter før den prises, og en Apex posthook til å håndtere prisendringer for grupper og andre Tilbud-objektelementer etter prising. Når en selger konfigurerer et produkt eller endrer en gruppe tilbudslinjer, endrer prisprosedyreplanen prisen basert på instruksjonene i Apex.

Viktig

Når du bruker Revenue Cloud, må eventuell Apex du legger til, være det første eller siste elementet i Prosedyreplan-utførelsessekvensen.
Eksterne oppkall fra en Apex-krok støttes bare når forespørselen Plasser salgstransaksjon utløses via Salesforce-brukergrensesnittet eller Place Sales Transaction API. De støttes ikke når forespørselen utløses fra Apex eller Flyt.
Eksterne oppkall i Apex støttes ikke når Double Persist-modus er aktivert. Kontakt Salesforces kundestøtte for å få mer veiledning.
Eksterne oppkall i Apex kan påvirke ytelsen. Så forutsigbare tjenestenivåmål (SLO-er) kan ikke garanteres.

Forsikre deg om at Prosedyreplanorkestrering for prising er slått på.
1. Skriv inn Omsetningsinnstillinger i Hurtigsøk-feltet i Oppsett, og velg deretter Omsetningsinnstillinger.
2. Finn og aktiver om nødvendig innstillingen Prosedyreplanorkestrering for prising.
3. La innstillingen Ekskluder standardpriser og prosedyrer for salgstransaksjonstype være deaktivert.

Definer klasser for Apex som skal legges til i prisprosedyrene.

Skriv inn Apex i Hurtigsøk-feltet i Oppsett, og velg deretter Apex-klasser.
Velg Ny for å opprette en ny Apex-klasse.

Denne prehook (ApexDmAttributePreHook) oppdaterer for eksempel verdiene for dynamiske attributter med navnet Display_Size basert på visningsstørrelsen. Flere eksempelklasser vises i Eksempelklasser for Apex Pricing Hooks på slutten av disse trinnene.
