Putaway Strategies
Putaway Rules and Strategies
A putaway strategy is a technique used to determine the bin location for a quantity of product based
on the characteristics of the product, the physical nature of the storage type and section in which the
bins are located. In EWM the putaway and removal strategies are implemented in most cases by
making several configuration settings in one or more of the following fields in the storage type
definition:
Storage Behavior
– blank - Standard
– 1 - Pallet storage
– 2 - Bulk storage
• Putaway Rule
– 2 - Additions to existing stock
– 3 - Consolidation Group
– 4 - General Storage Area
– 5 - Empty Bin
• WT Generic
– blank - Not generic
– 1 - Only St. Type - Section
– 2 - Only Storage Type

Putaway Strategies
A) Manual Entry :
Use
The system does not determine a storage section or a storage bin. You enter the
destination storage bin manually when the warehouse task is created. You use this
procedure if the search for a suitable storage bin is performed on-site by the warehouse
worker. First the warehouse worker searches for the suitable storage bin. Then the system
automatically determines the data using the storage bin (for example, the storage type) in
the warehouse task.
Prerequisites
You have made the following settings for the storage type in Customizing for Extended
Warehouse Management (EWM) under Master Data  Define Storage Type :
You have chosen the Standard Warehouse value in the Storage Behavior field.
You have chosen the Empty Bin or Addition to Existing Stock/Empty Bin value in
the Putaway Rules field.
You have chosen the Only Storage Type value in the WT Generic field.

Putaway Strategies
B) Fixed Storage Bin :
You apply this strategy if you want to put
away a product in fixed storage bins in a
storage type. You use this strategy primarily in
storage types from which picking is done
manually. You assign fixed storage bins
manually.
If you want to put away a product without
fixed bin assignment in a storage type for
which you have defined the strategy “Fixed
Storage Bin”, the system determines a suitable
storage bin and assigns it to the product as a
fixed storage bin.
The following figure is an example of a fixed
bin assignment. In this example, warehouse
0001 has several fixed storage bins: FIX-AA,
FIX-BB, and FIX-DD. Multiple fixed storage bins
can be available for a product, for example,
FIX-1-BB and FIX-2-BB for product BB.

Putaway Strategies
Prerequisites
You have defined fixed storage bins in the master data for Extended Warehouse
Management (EWM) under Storage Bin  Maintain Fixed Storage Bin.
You have made the following settings for the storage type in Customizing
for EWM under Master Data  Define Storage Type:
You have chosen the Addition to Existing Stock/Empty Bin value in the Putaway
Rules field.
You have set the Fixed Bins Allowed indicator.
You have defined a maximum number of fixed storage bins in the Max. Fixed Bins field (you
can also make this setting in the product master).
You have chosen the Addition to existing stock permitted value in the Addn.Stock
Forbidden field.
You have chosen a method in the Capacity Check field to activate the capacity check.

Putaway Strategies
C) General Storage
The system uses this strategy to find a storage
bin in a general storage area. General storage
is a type of warehouse organization in which
you define a single storage bin per storage
section. The quants in the storage bin can also
be in the form of mixed storage. For each
storage type, you can define one or more
general storage areas.
The following figure illustrates general
storage. Two general storage areas (bin XXX
and bin YYY) are available with mixed storage
in storage type 0005. This means that you can
put away product F in bin XXX even though
product X has already been put away there.
Prerequisites
You have made the following settings in Customizing for Extended Warehouse Management
(EWM) under Master Data  Define Storage Type:
You have chosen the General Storage Area value in the Putaway Rules field.
You have chosen the Mixed Storage Without Limitations value in the Mixed Storage field.

Putaway Strategies
D) Addition to existing stock
With this strategy, the system prefers to put
away stock in storage bins that already
contain stock of the relevant product. A
prerequisite for addition to existing stock is
that sufficient free capacity still exists in the
relevant storage bin. If the system cannot find
a storage bin with the same product or if the
storage bin does not have sufficient free
capacity to store additional quants, the
system searches for the next empty storage
bin.
This strategy violates the FIFO principle. For
this reason, you should only use this strategy
in situations where you have insufficient
space.
The following figure shows an example of addition to existing stock. You want to put away
product AA. Since AA is already occupying a storage bin and free capacity is still available,
you can add the product to the existing stock

Putaway Strategies
Prerequisites
for EWM under Master Data  Define Storage Type:
You have chosen the Addition to Existing Stock/Empty Bin value in the Putaway
Rules field.
You have specified in the Addn.Stock Forbidden field whether or not you want to allow
additions to existing stock.
If you want to allow additions to existing stock, choose “ ” (Addition to existing stock
permitted) or “M” (Addition to existing stock via addtn ID in product master). If you choose
“M”, you must choose the required value for the Addit.to Exist.Stock indicator in the
product master.
You have chosen a method in the Capacity Check field to activate the capacity check.
You have chosen the value 3 in the Mixed Storage field (one HU allowed per bin, in other
words, mixed storage is not permitted).

Putaway Strategies
E) Empty Storage Bin
Use
With this strategy, the system proposes an empty storage bin. You can use this strategy to
support warehouses that are organized randomly, where products are stored in individual
storage sections. This strategy is especially suited for high rack storage and shelf storage.
Prerequisites
You have made the following settings for the storage type in Customizing for Extended
Warehouse Management (EWM) under Master Data  Define Storage Type :
You have chosen the Empty Bin value in the Putaway Rules field.
Optionally, you can change the sort sequence of the storage bins that has an effect on the
determination of the empty storage bin under SrchRule EmptyBin .

Putaway Strategies
F) Near Fixed Picking Bin
You use this strategy when you put away products in a reserve storage area. This
strategy is intended for situations where reserve storage bins of a reserve storage
type are located directly above the fixed storage bins in a picking storage type
(nearby reserve).
You can configure whether the system checks if a fixed storage bin is available. You
can set up your system in such a way that it first searches for a fixed storage bin in
a picking storage type. If it does not find an empty bin, it then uses the Near Fixed
Picking Bin strategy to search for a bin in a reserve storage type that is as close as
possible to the fixed storage bin of the product.
The system first tries to find a reserve storage bin in the stack where the fixed
storage bin is located. Here the system starts on the lowest level and works its way
up. If it does not find an empty bin, it searches to the right of the fixed storage bin
and then to the left in the same aisle, before searching in the adjoining aisles.
Here it always searches from the bottom upwards.
If multiple fixed storage bins are available for the product in the picking storage
type, the system takes the first fixed storage bin that it finds as the starting point.

Putaway Strategies
Prerequisites
for Extended Warehouse Management under Master Data  Define Storage
Type :
You have chosen the Empty Bin or Addition to Existing Stock/Empty Bin value in
the Putaway Rules field.
You have chosen the Near to Fixed Bin value in the SrchRule EmptyBin field.
You have defined the bin names according to the same Structure of Storage Bin
Number for Shelf, Stack, Level in the picking storage type and the reserve storage
type. For more information about this structure, see Customizing for
Extended Warehouse Management under Goods Receipt

Putaway Strategies
BULK STORAGE
Definition of bulk storage:
Warehouse area without shelves where similar pallets or containers are stacked.
In many instances, the storage bins in bulk storage are separated by lines on the
warehouse floor. Each bin generally holds only one product, for example barrels
with a specific color. Also, products such as canned goods, consumer products
such as soft drinks that come in large quantities and require a large amount of
storage space are often stored in bulk storage. The advantages of bulk storage
include:
• Reduced need for physical storage bins
• Fast access to the products
• Clear structuring of the warehouse (into blocks and rows)

Putaway Strategies
Characteristics of bulk storage:
• Coordinate structure: The warehouse space is divided into blocks, which in
turn are divided into individual rows.
• One storage bin per row: In the system, a row is created and managed as a
storage bin.
• Mixed storage: You do not put away HUs with different products in the same
row. However, in general, all combinations of mixed storage are allowed in
bulk storage. You can also define that all products in the storage bin must
have the same batch.
• Different HU types: In bulk storage, you often manage different HU types
with different dimensions.
The following are the Storage Type configuration settings required to implement
the Bulk strategy:
• Storage Behavior: Bulk Storage
• Putaway Rules: Additions to existing stock/Empty Bin
• Addn.Stock Forbidden: Addition to existing stock permitted
• Do not activate the HU Type Check or Capacity checking

Putaway Strategies
Pallet Storage
Using this putaway strategy, the system processes different HU types (for example, pallets) and
allocates them to a suitable storage bin section. This storage strategy is commonly used in storage
types that represent areas of pallet racking in the warehouse. One storage bin is often divided into
several smaller sections. In this strategy, you can only put away the same HU types in a storage bin.
The first time that the system assigns a pallet in this storage bin, it determines the
storage bin sectioning depending of bin type and HU type. The system also generates
the storage bin sections as storage bins in the system (for example 02-08-01/1, 02-08-
01/2 and 02/08-01/3) on the basis of the first HU that is put away. The storage bin
sections are deleted as soon as you have removed the last HU from the storage bin.
