Explanation
When you post a goods receipt to stock with reference to a purchase order, you can perform the following actions:
Split the quantity received to multiple storage locations, which means that you can distribute the goods receipt quantity among different places where materials are physically stored within a plant.
Post partial order quantity, which means that you can receive multiple partial deliveries for the same purchase order item. References: SAP S/4HANA Sourcing and Procurement | SAP Learning, Course S4510, Unit 2, Lesson 1.
