In the SAP S/4HANA Cloud Sell from Stock (BD9) process, the billing due list is updated upon the successful posting of the goods issue (PGI). The PGI step is the logistical and financial trigger that confirms the goods have left the company's possession and ownership has been transferred. This event makes the outbound delivery relevant for billing, causing the system to add an entry to the billing due list, which serves as a worklist for creating customer invoices.

B. Proof of delivery: This is an optional step that confirms customer receipt. While it can be a prerequisite for invoicing in some scenarios, the delivery becomes billing-relevant and updates the due list at goods issue.

C. Execute picking: Picking is an internal warehouse activity to prepare goods for shipment. It has no financial impact and does not make the delivery relevant for billing.

D. Create delivery: Creating the delivery document only initiates the shipping process. At this stage, the goods have not been shipped, and the criteria for billing have not yet been met.
