Physical Inventory WM point of view
Purpose of Warehouse
· Define and manage complicated warehousing structures
· Information of material at Bin level
· Optimize material flow using advanced put-away and picking techniques
· Material attributes are taken into account
· Capacity Check at Bin level
· Process goods receipts, goods issues and stock transfers accurately and easily
· Interface with other module/sub-modules
· Shelf life items and Hazardous items handling
Warehouse Management
• Highest level in warehouse - warehouse number
• Assigned to a combination of Plant and Storage Location

Storage Type
A storage type is a storage area, warehouse facility, or a warehouse zone that you define in Warehouse Management (WM) for a warehouse number. This is a physical or logical subdivision of a warehouse complex that is characterized by its warehouse technique, the space used, its organizational form, or its function
You can define the following frequently-used physical storage types in WM:
• Bulk storage• Open Storage• High rack storage• Picking area• Shelf storage
In Warehouse Management (WM), a storage section is an organizational subdivision of a storage type that groups together storage bins with similar features for the purpose of putting away stock.
The criteria for grouping bins can be defined on a user-individual basis for example.• Heavy parts • Bulky materials• Fast-moving items• Slow-moving items• Special Temperatures• Fire Protection• Others

Storage Bin Type and Blocking Reason
A storage type generally contains several storage spaces or slots. These are called storage bins in Warehouse Management (WM). The storage bin is the smallest available unit of space in a warehouse. The storage bin therefore describes the position in the warehouse where the goods are or can be stored. Since the address of a storage bin is frequently derived from a coordinate system, a storage bin is often referred to as a coordinate. The coordinate 01-02-03 for example, can refer to a storage bin in row 1, stack 2, and level 3.
You can also define the following additional characteristics of a storage bin:
• Maximum weight • Total capacity• Fire containment section• Storage bin type (for example,
for small or large pallets)

Putaway and Pickaway Strategies
Putaway and Pickaway Strategies
Putaway and Picking Strategies:In the Warehouse Management (WM) application component, you employ putaway and removal strategies used by the system to search for storage bins in the most expeditious manner.
Putaway Strategies:For inbound movements, in conjunction with controls entered in the material master record, the putaway strategies assist the WM system to utilize the available warehouse capacity, automatically assigning optimum locations for goods received in the warehouse.
Picking Strategies:For outbound movements, the system uses similar user-defined controls to execute the appropriate picking strategy to assign the best picking location. If you decide to manually process certain stock movements, you can change source and destination storage bins that are automatically proposed by the system.
When the system creates transfer orders to move goods into or out of the warehouse, you do not have to intervene when it comes to finding storage bins. This guarantees that stock movements are processed quickly and consistently.

Goods Receipt Process
Goods Issue Process
The system must now determine in which storage type the material should be put away and Pickaway. You define this information in the storage type search table. To make entries in this table, see the section on defining the storage type search sequence under Strategies in the Warehouse Management IMG documentation.In the storage type search table, you can define a search sequence with up to thirty storage types. (Make sure that you enter an E for putaway and A for Pickaway in the column Activity). This means that the system uses the search sequence for searching for a destination storage type.
Storage Type Search
Storage Section Search
You can divide a storage type into several storage sections (see The Storage Section) in which various materials can be stored. You can use these storage sections, for example, to ensure that frequently used materials ("fast-moving" items) are stored in the front of the warehouse while seldom used materials ("slow-moving" items) are stored in the back of the warehouse. A storage type is divided into storage sections on the basis of storage bins. When you create a storage bin, you assign it to a storage section.
Storage Bin Type Search
Storage Bin Search:
Once the storage type has been determined, the system then searches within the storage type to find an appropriate storage bin in which the material can be put away and removed. To find a storage bin, the system uses a search strategy that has been defined for the storage type. For each storage type you can define a putaway and Pickaway strategies.
Strategies – Putaway and Pickaway
You can also define storage types in WM that are shared by both the Inventory Management (IM) and Warehouse Management (WM) application components. These are called interim storage areas and include the following.• Goods receipt area • Goods issue area • Interim storage area for differences • Posting change zone
