This video provides a comprehensive understanding of Quality Management (QM) in the sales process within the SAP S/4HANA system. Here are the key points:

1. QM in Sales: Quality Management plays a crucial role in the sales process. When products are delivered to customers, they undergo a quality inspection to ensure they meet the required quality standards.
2. Inspection Process Flow: The inspection process includes the creation of an inspection lot, data in the inspection lot, inspection lot structure, sample determination, results recording, defect recording (optional), usage decision, and stock posting.
3. Inspection Lot: An inspection lot is created when a production order is released. It contains several operations, each reflecting different inspection stages for the product. Each operation can contain several inspection characteristics.
4. Results Recording and Usage Decision: After the sample quantity calculation, the next step is results recording. This can be done manually or automatically. After results recording and inspection completion, a usage decision (UD) is made for the inspected goods. The UD specifies whether the goods in the inspection lot have been accepted or rejected.
5. Stock Posting: After the UD, if the lot has been created because of any goods, stock posting can be done. The video demonstrates how to post stock from quality inspection to unrestricted use or blocked stock, depending on the UD.
6. Inspection Setup in Material Master: To trigger an inspection lot, the inspection type required is 10 for quality inspection during delivery and it needs to be activated in the Material Master in the QM view.
7. Quality Inspection during Delivery: The video discusses the scenario where quality inspection is performed during delivery. This is often required in industries where the customer expects a quality inspection of the material just before delivery.
8. Quality Info Record: A Quality Info Record is maintained for a material and vendor combination. If it is maintained, the system will allow the creation of a purchase order, meaning the supplier is released to supply the material to the plant.
