What tasks does the SAP Warehouse Management system accomplish?
Management of complex warehouse structures with various types of storage areas (high rack random storage, block storage, fixed bin storage, and so on) within one or several plants down to the storage bin level.
Processing of all stock movements such as goods receipts, goods issues, stock transfers using stock placement and stock removal strategies, also taking the characteristics of the individual materials into account. This feature includes the consideration of materials with a shelf-life expiration date.
Support during inventory of storage bins.
The control of information transfers between the WM system and automated warehouses.

WM Warehouse Management
Remote data processing
Delivery processing
The Warehouse Management system is interfaced to other SAP system modules that provide the following functions:
All goods movements in the WM system affect data posted in the Inventory Management system.
The supply of materials in connection with the Production Planning system.
The processing of deliveries in conjunction with the SD Shipping system.
The handling of inventory samples in connection with the Quality Management system.
The processing of transfer requirements and transfer orders using hand-held terminals.

Possible representation of the physical structure in the Warehouse Management system:
The entire warehouse structure is managed under a warehouse number.
The various storage areas are defined as storage types that are differentiated according to their organizational and technical characteristics.
Examples: - GR area
- picking area with fixed storage bins
- high rack storage area with random picking
- block storage area with rows of the same material

Picking area

5. Storage Bins and Quants
Bin type
High bins
Lower bins
Storage section
Fast-moving items
Slow-moving items
Within each storage type the individual storage bins are defined. A storage bin is the smallest geographical or organizational unit (also called "coordinate") that can be addressed by the system.
Example: (aisle 02, stack 04, level 09)
Storage bins are identified by a bin type.
Example: Bin type P1 for high bins
Storage bins are organizationally grouped into storage sections.
Example: Section 001 for fast-moving items
The existence of a material in a bin is defined as a quant.
In bins designated for single-material storage, only one quant may be stored in the storage bin.
In bins designated for mixed storage, different materials (or batches) may be stored in the storage bin.
The material quantity in a quant can be increased by an addition to existing stock.
A specific type of palletization or container (for example, wire box or Europallet) for a quant is designated by the storage unit type (SUT) (for example, WB, E1). Only storage units of a particular SUT are allowed to be stored in a particular bin type.

Storage locations
In an Inventory Management system without Warehouse Management, the various warehouses are defined as storage locations.
Example: Plant Storage location High rack storage
0002 Block storage
The stock quantities are managed in cumulative form at the storage location level.

Storage types
All warehouses that are managed under one warehouse number with the Warehouse Management system are grouped together per plant in one storage location (for example, 0088).
The storage location of a plant is assigned to a warehouse number in which the various storage areas are defined as storage types.

Storage types
It is possible to manage warehouse areas from different plants or different company codes under one warehouse number.
Warehouse areas (that is, storage types) that are not managed by the Warehouse Management system are defined in the Inventory Management system as storage locations (for example, storage location 0001).

Storage bins
The master data of the Warehouse Management system is divided into:
warehouse data (for example, capacity, fire-containment sections)
material data (for example, weight, hazardous material data, palletization instructions).
The characteristics of the warehouses and the materials are taken into consideration for all stock movements.

12. Storage Bin Data Warehouse no.: 001 Storage type 001

Storage bin type
Blocking indicator

Quant data
Material identification
Stock quantity

Inventory
Each storage bin is defined in the system by a master record. The master record contains the following information:
the characteristics of the bin (storage section, storage bin type, max. weight, blocking indicators).
You create this data manually when you create the master record.
bin usage and inventory information (number of quants, weight used, data of the last movement, inventory data, blocking indicators).
This data is automatically maintained by the system during a stock movement.
Whenever a storage bin becomes occupied, the system creates a quant that contains the following data:
storage bin identification
material identification (material number, plant, batch, stock category, special stock)
movement data (for example, GR date)
stock quantities (total, available, currently in transfer for stock placement or stock removal)
inventory data
blocking indicators

unit of measure
The Warehouse Management system uses the following units of measure:
the base unit of measure (or stockkeeping unit), which is the basis for inventory management and evaluation. Quantities in alternative units of measure are always converted to the base unit of measure using the conversion factor.
the alternative unit of measure for inventory management (unit of issue), purchasing (order unit), and sales (sales unit). These units of measure are defined at plant level.
