What is required to perform explicit counting using the Quality Inspection Engine?

Comprehensive and Detailed In-Depth Explanation:

Explicit counting in the Quality Inspection Engine (QIE) in SAP EWM involves a deliberate count of stock during an inspection, often triggered by quality requirements. Option B ("Sampling procedure") is correct because it defines how many items are inspected (e.g., percentage or fixed number), configured in the quality management (QM) system and linked to EWM. Option C ("Inspection rule") is correct as it specifies the inspection process, including whether explicit counting is required, and is maintained in EWM under SPRO: SCM Extended Warehouse Management > Quality Management > Inspection Rules. Work center (A) is relevant for production processes, not QIE counting, and QM integration (D) is a prerequisite for QIE but not a direct requirement for explicit counting itself.
