Question: What do default selling, default purchasing, default receipt, and default display units of measure represent when creating a product?
Answer: A product record is created with each of these units of measure as well as a stocking unit of measure. These determine the defaults during customer order processing, purchase order creation (using demand forecasting, min-max buying method, or straight line purchase orders), purchase order receiving, and for display in inquiries and reports.
