Transportation Management with SAP LES

Lean WM 7.4
you try to obtain information on lean WM from an SD or LE consultant, you often
hear that you’d be better off to ask your WM consultant. If you then speak with
your WM consultant, you might be told that lean WM is part of LES. In fact, you
do make Customizing settings for lean WM in LES, but users execute functions
that are part of WM. But I do not wish to keep lean WM from you completely, and
will describe some of its approach.
Lean WM does not support organization of a random warehouse. It is set up to
assign a fixed storage location in your warehouse to your materials. The fixed
location is stored in the material master. Complex warehouse structures cannot be
mapped with lean WM.
Other important differences exist between lean WM and a warehouse management
system. Stocks in lean WM are not carried at the level of the storage location.
The storage location is the lowest organizational level at which stock is carried.
Only WM or an external warehouse management system knows the sock at each
storage location in your warehouse.
The advantage of lean WM is that (unlike WM), you do not need to maintain any
strategies for placement into and removal from storage, you cannot carry any palette
stocks, and you do not have to perform inventory in the SAP system at the
level of the storage location and so on. But you can or must perform some processes
in both systems (WM and LES). These processes include creating transport
orders, the resulting printing of picking lists, confirming transport orders, and
automatic updating of the picked quantity in the delivery document.
7.4.1 Organizational Structure of Lean WM
This section introduces the individual steps of lean WM. The end of the chapter
also provides an example.
Warehouse Number
In the first step in lean WM (as in WM), you assign a warehouse number. You assign
the warehouse number to a storage location in a later step. This assignment makes
the storage location a lean WM storage location.
