De code moet in een Billing-customizer geplaatst worden die gecreëerd werd vanuit de bijbehorende sequentie. Dit implementeert de volgende interfaces:

Maakt vooral gebruik van events van de BillingEngine van het huidige document;

  • AfterInsertItem
  • BeforePayment
  • AfterSave

De code wordt als volgt samengesteld:

Eerst moet men:

  • het veld lignes_v.id_boncad (alter table LIGNES_V add ID_BONCAD char(35) not null constraint DF_LIGNES_V_ID_BONCAD default '') toevoegen
  • Een SQL-index toevoegen op het veld (create index ID_BONCAD on dbo.LIGNES_V (ID_BONCAD))
  • Update het databaseschema via de Geavanceerde Tools
  • 2 artikels creëren (zonder voorraadbeheer) 
    • "Cadeaubon" (Sleutel1 = "BONCAD")
    • "Gebruik cadeaubon" (Sleutel 1 = "UTILBONCAD").

Waarschuwing, indien u de barcode van de voucher moet inkorten (billingEngine.PiedsVRecord.ID + l.DL_ID);), dan moet u de waarde van l.DL_ID behouden en niet billingEngine.PiedsVRecord.ID (dat kan identiek zijn aan meerdere vouchers).
