Information about Stock Placements
When stock is placed into the warehouse, it generally is transferred from the interim storage area for goods receipts. Information about the source (interim storage type, interim storage section, and interim storage bin) is recorded in the transfer requirement or the system determines it from the WM movement type.
Searching for a Storage Type
The system must now determine into which storage type the material should be placed. You define this information in the storage type search table.
In the storage type search table, you can define a search sequence with up to ten storage types. Be sure to enter an e (for stock placement) in the Act. column. This means that the system uses the search sequence to find a destination storage type.
The list of storage types is hierarchical, that is, the system searches for empty storage bins in the first storage type, then in the second storage type, and so on. The table entries
that the system uses for this search depend on the movement type and/or the material being placed into storage.
You can also group materials together by the storage type indicator so that the system uses the same search sequence and stores the group of materials in the same storage type or types. To implement this you define:
a storage type indicator in the material master record (the Placement Storage Type indicator field)
a storage type indicator in the storage type search (in the Type Indicator field)
Reference to Movement Type
Entries in the Ref column of the storage type search table influence storage type search
according to movement type.
To link a movement type to a storage type search sequence, you enter a reference number in the Reference Type Search column of the table displayed. This same number will also appear in the Reference storage type search field for each movement type selected.
Access Optimization for Storage Type Search Strategies
When storage type indicators are used and several materials with different stock categories (such as special stock) exist, the number of entries in the storage type search table can become very large. To decrease the number of these entries, you can define an access strategy for the storage type search table using the access strategy table.
Hazardous Materials
You can also influence storage type search according to hazardous material storage classes and water pollution classes.
Searching for a Storage Bin
Once the storage type has been determined, the system then searches within the storage type to find an appropriate storage bin in which the material can be placed. To find a storage bin, the system uses a search strategy that has been defined for the storage type. For each storage type you can define one stock placement strategy.
Regardless of the put-away strategy, there are two other factors that affect how the system searches for empty storage bins.
· storage section · storage bin type
Both of these factors are independent of the strategy that is used for stock placement. Both can be used with all stock placement strategies with the exception of fixed bin strategy, for which storage sections cannot be used.
You can divide a storage type into several storage sections in which various materials can be stored. You can use these storage sections, for example, to ensure that frequently used materials ("fast-moving" items) are stored in the front of the warehouse while seldom used materials ("slow-moving" items are stored in the back of the warehouse. A storage type is divided into storage sections on the basis of storage bins. When you create a storage bin you assign it to a storage section. If storage section checking is active for the storage type, then the system searches in the storage type only for those empty storage bins in storage sections that have been allowed for the material being placed into storage. When you are creating a transfer order and manually enter a storage bin, then the system checks whether the bin is in a storage
section that is allowed for the material.
Storage bin type search
In one storage type you may have storage bins of different sizes. When the system places goods in storage, it can search for a storage bin that will accommodate a specific storage unit type. When you create a storage bin you assign it to a storage bin type. In the table for assigning storage unit types to storage types, you can define up to ten storage unit types that can be accommodated in each storage type. Next you must assign the storage bin type to each storage unit type. In the storage bin type search table, you can define up to ten storage bin types that can be used for each
storage unit type in a storage type.
As a final step, you must activate the storage unit type checking for a storage type. The connection between a material and storage unit type checking is made in the material master record. You can define up to three different palletizations (storage unit type and number of units of material per storage unit type) for a material. If storage unit type checking is active for the storage type, the system first determines if the storage unit type for the material can be placed in the storage type. Next the system searches for an empty storage bin in the first storage bin type that can accommodate the storage unit type. If it does not find a bin, it then searches in the second storage bin type, and so on. When you are creating a transfer order and manually enter a storage bin, then the system checks whether the bin belongs to one of the allowed storage bin types.
