Which feature is needed to split Order Products into different Invoice runs?

In Salesforce Revenue Cloud, the feature needed to split Order Products into different Invoice runs is

the Invoice Group. The Invoice Group field on the order product is used to define more levels of

grouping. After the invoice run groups order products by their billing account and payment terms, it

then considers the order’s invoice grouping. This process is useful for invoicing certain types of order

products separately from your other order products1.

Grouping Order Products into Invoices - Salesforce

To split Order Products into different Invoice runs, the feature needed is "Invoice Group." Salesforce

Billing allows for the customization of invoice groups, enabling the billing of order products that

meet specific criteria separately. This functionality is particularly useful for separating invoices with

different billing or payment terms and for consolidating several order products into a single invoice

when needed. By defining an Invoice Group ID, users can control the invoicing process for order

products more granularly, ensuring that invoicing aligns with business requirements  .
