Comprehensive and Detailed In-Depth Explanation:

Separate storage locations in SAP EWM (mapped from ERP) manage stock purposes. Option D ("Distinguish material that is supplied for production from material which is available for sales") is correct because storage locations can segregate production stock (e.g., “PROD”) from sales stock (e.g., “SALE”), configured via warehouse number mapping in SPRO: SCM Extended Warehouse Management > Interfaces > ERP Integration. Options A, B, and C are managed by stock types or processes, not storage locations.
