Outbound delivery is the step that turns a confirmed customer order into goods leaving the warehouse. In SAP the flow is: sales order (VA01) → outbound delivery (VL01N) → picking (transfer order or EWM warehouse task) → packing (handling units) → post goods issue (PGI) → billing (VF01).
When the delivery is created, SAP checks availability, the shipping point, the route and the loading date. Picking moves the exact quantity from the storage bin to the staging area; the picked quantity must match the delivery quantity before goods issue. Packing records the cartons or pallets as handling units so the customer and carrier can see what is inside each box.
Post goods issue (movement type 601) reduces unrestricted stock, posts the cost of goods sold in finance and makes the delivery ready for billing. After PGI the stock is no longer yours in the system, so wrong PGIs must be reversed with VL09 (movement 602), not by a manual stock adjustment.
Example: a customer orders 200 pumps. The delivery is created for 200, picking confirms 190 because 10 are damaged. The planner either reduces the delivery to 190 and creates a backorder, or picks 10 from another bin. PGI is posted only for what is physically loaded. KPIs: on-time-in-full (OTIF), pick accuracy, order-to-ship lead time and number of PGI reversals.
