Quant in Warehouse Management is the smallest physical unit of stock stored in a specific storage bin. It represents a distinct material quantity with unique attributes, enabling precise inventory tracking and movement within the warehouse.
Understanding Quants is essential for efficient warehouse management, as all material handling activities in SAP WM revolve around them.
What is a Quant in SAP R/3?
In SAP, Quant is the content of a storage bin and represents a specific material quantity stored in that bin. It serves as the smallest unit of inventory tracking in SAP Warehouse Management (WM). Materials are always considered and moved in the form of Quants, and the specific number of items or their unit of measure (e.g., pieces, kilograms, or liters) is less relevant.

Key Concept: Quant Formation
The SAP WM system uses predefined criteria during putaway and stock removal to determine whether a material quantity forms a single Quant or multiple Quants within one or more storage bins. These criteria are:
- Material Number: Identifies the material stored.
- Stock Type or Category: Differentiates unrestricted-use stock, quality inspection stock, or blocked stock.
- Special Stock Assignment: Defines special categories like consignment stock or project stock.
- Plant and Storage Location: Links the quant to specific organizational units.
- Batch Number (if applicable): Tracks materials by production batch.
