This configuration option provides the ability to apply a service credit when pre-paid and non-subscription offerings are purchased. When set to True, the parameter Do Not Consume Service Credits on Pre-Paid Item Invoicing ensures that whenever a pre-paid inventory item is invoiced, the invoice line items as well as related taxes resulting from that inventory item do not consume any service credits on the account. If there are additional line items on the invoice, such as non-prepaid inventory items, then service credits are consumed for these items.
