The Warehouse Number 


You normally define an entire physical warehousing complex in WM using a single warehouse number. The warehouse number can be used to manage several storage types located in one or more buildings.

As an example, the warehouse for company XYZ consists of a(n)

In WM, all of these can be combined under one warehouse number and depicted in a diagram.


The warehouse number encompasses the organizational and physical aspects of a warehousing complex as a single concept. You define the warehouse number in a table with various control parameters that apply to all the elements of the warehousing complex.

For example, if you want to use capacity checking in the warehouse according to weight, the unit of weight is defined at the warehouse number level. Additionally, you define the default units of measure for WM documents, the type of picking and special interfaces, such as external or WM-PP, at this level.

If necessary, you can still change all of these control parameters after you have "gone live" with WM in the active mode.

Each of the storage areas in the above list are called storage types in WM (see The Storage Type).

How can you implement the warehouse number optimally in WM?

We recommend using one warehouse number for each group of storage areas or buildings (warehousing complex) that is situated in the same geographical area. If your warehousing facilities are located in different cities or are physically separated by a longer distance, it is meaningful to assign each warehousing complex to a separate warehouse number and storage location. This depends upon each individual situation.
