Activate
Storage Bin Type Search
The Warehouse Management System (WMS) can
manage different sizes of
storage bins within a . The storage bins are determined during
the storage bin search:
In this case, the
SAP System suggests the relevant storage unit type for the putaway as a
default.
2. Then the WMS
checks if the storage unit which is to be placed into stock may be put away in
the storage typed determined by the storage type search.
The table "Allowed
storage unit types per storage type" contains details on which storage unit
types (SUTs) may be used in which storage types.
This table defines
which storage unit type may be used within each storage type. Up to 10 storage
units may be assigned per storage type.
If more than 10
storage units are required per storage type, it is possible to activate the
weak SUT check.
To do this, enter
*** in this table as the allowed SUT. This has the effect
that, in theory, all SUTs are allowed for this storage type. The system then
searches for a bin that matches the storage unit type according to the allowed
storage bin type per SUT.
3. Then the
system searches for a suitable storage bin using the putaway
strategy.
- For this purpose you have assigned a
storage bin type to each storage bin in the master
data.
- Via the table "Storage bin type search" the
WMS finds information on which SUTs match which storage bin types.
The search for a subsequent storage bin type is restricted to the permitted
storage bin types which are run through sequentially according to the sequence
of entries in this table.
4. If you
manually enter the storage bin during putaway, the WMS checks if the SUT may
be used on the relevant storage bin.
Requirements
The storage unit type check parameters must be
activated. This check is independent of a particular strategy. You can use it
for all
putaway strategies.
Recommendation
If you wish to implement the above weak
SUT-check, check your table options exactly as performance problems
may arise if the customizing option is not properly set.
The following example should
illustrate these problems and their solution:
- Storage bin types P1 P2 P3 P4 P5 are allowed
for storage unit type E1. E1 is to be placed in stock in storage type 001.
Here there are only storage bins of type P0.
- Normally E1 would not be included in the
storage unit types allowed for storage type 001. The WMS recognizes this and
searches for a bin in the next storage type.
- A weak SUT check is when the database is
accessed 5 times unsuccessfully. This number increases depending on how many
different storage sections you work with at one time.
You can check the Customizing options via the
storage bin determination log (transport order management). Multiple access to
the database does not greatly impair performance. The number of times the
database is accessed in this way can be decreased using an optimized
storage type search.
Activities
Set the parameters for bin type search in the
following sequence:
1. Bin
types
Divide your storage
bins into groups (for example, large bins, small bins).
2. Check your
warehouse master data and, if necessary, fill in any missing storage bin
types.
Classify your
storage units (for example, by palette type).
4. Check your
material masters and add palletization data, if this has not already been
done.
5. Allocation
of storage unit types / storage type
For each storage
type, define which storage unit types may be placed into stock in this storage
type.
6. Allocation
of storage unit types / storage bin types
For each storage bin
type, define which storage unit type may be put away.
7. Activate the
storage unit type control function in the putaway control parameters for the
desired storage bin.
