The document provides guidelines for codifying parts and warehouse infrastructure for a warehouse management system (WMS). It specifies a fixed-length 16-character coding structure for parts that includes fields for product category, core product, model, system, sub-system, and sequential part number. It also describes coding warehouse locations with fields for warehouse ID, shed/building ID, aisle, bay, level, and bin position. Sample labels are shown for selective racking and shelving bins.
