Calling the Revenue Recognition Service with APEX Triggers

1//In this example, we want to create a revenue schedule for an invoice line after its status changes to Posted.
2//The example uses the InvoiceLine object in the billing package, where the API name is blng__InvoiceLine__c.
3//For your specific use case, replace blng__InvoiceLine__c with the desired API name object.
