During billing processing, you create, change and delete billing documents (invoices, credit memos, debit memos, etc.).

You can create billing documents:

• with reference to a sales order
• with reference to a delivery
• with reference to external transactions:

You can refer to an entire document, individual items or partial quantities of items.

You can create billing documents in the following ways:

• by having the system process a billing due list automatically as a background task
• by processing manually from a worklist
• by creating a billing document explicitly

You can also use the following forms of settlement:

• by combining several SD documents into a collective billing document
• by billing one or more SD documents with several billing documents (this is called an invoice split).
• by creating an individual billing document for every sales document
