Transportation Management with SAP LES

Organizational Structures in Logistics
Within a storage type, storage areas can be defined. Structural differences of the
storage bins (high storage bins in a rack, low storage bins), for example, can result
in certain materials only being stored in certain bins (storage areas depending
on pallet height). If stocks are divided even further and are managed per pallet,
the term storage units is used in WM. This allows you to immediately see which
materials are stored in the individual storage units and in which storage bin they
are stored.
2.2.1 Warehouse Number
In WM, you define a warehouse number for a warehouse complex (building, site).
You can group together multiple storage locations and plants to a warehouse number.
The stocks at warehouse number level are only recorded by quantity.

2.2.2 Storage Type
Within a warehouse complex (= warehouse number), you will find different storage
areas (high-rack storage areas, block storage areas, shipping deployment areas,
picking areas, etc.), which are called storage types in WM. However, even identical
storage areas that differ only in their organization have to be defined as separate
storage types (there may be shelves in a picking area that require a capacity check
at the storage bin level, whereas other shelves do not require a check).
In addition, there are interim storage areas, which can be difficult to understand,
particularly if WM has only been implemented recently. Interim storage areas (see
Figure 2.11) are not physical, but virtual storage bins. Even negative stocks are
allowed in these areas.
