The process of stock removal includes picking goods from storage bins in the warehouse and staging them in the destination storage bin. If you use the Warehouse Management system (WMS), you create a transfer order (TO) for all warehouse movements. You therefore execute stock removal based on a stock removal transfer order. The printed transfer order serves as a picking list.
To make the search for the right material for stock removal easier, the Warehouse Management system offers stock removal strategies. WMS selects the storage type and exact storage bin from which the material is to be picked, according to the stock removal strategy.
Process Flow
The outbound delivery or transfer requirement sends a request to the WMS to remove goods from stock.
You create a TO for the outbound delivery or for the transfer requirement.
You use a printout of the TO as a picking list.
When you confirm the transfer order, you confirm in the system that the physical removal of the goods from stock is complete. The material to be removed from storage is in the storage bin determined in the TO.
The system reduces the stock in the source storage bin by the quantity of the material that has been picked and posts this material quantity to the destination storage bin.
Process flow of stock removal
To remove the material from storage you create a transfer order (TO) for the outbound delivery. Several TO items can be created from one outbound delivery item. This is the case, for example,
if you have to pick the material for item 2 of the outbound delivery from three different source storage bins in order to remove the quantity specified in the outbound delivery from storage.
Item 2 of the outbound delivery creates three TO items.
The Warehouse Management system (WMS) uses the following stock removal strategies:
Stock Removal Strategies
Strategy
The System Searches
F
for the oldest quant using FIFO
(blank)
using stringent FIFO for all storage types
L
for the most recent quant using LIFO
A
for partial quantities first, then standard quantities
M
according to quantity
H
for materials with the shortest remaining time before the shelf life expiration date
P
for a fixed bin
User exit
with a customer-defined strategy
Prerequisites
For information about how to access the objects (tables or views of tables) for the stock removal strategies, see the corresponding section under Strategies in the Implementation Guide (IMG) for Warehouse Management.
Features
The system gets the information for the source and destination storage bins for stock removal as illustrated below.
Information on Stock Removal
When a material is removed from stock, it generally transferred to the goods issue interim storage area. The information about the destination (interim storage type, interim storage section, and interim storage bin) is either stored in the transfer requirement or the system determines it from the WM movement type.
Storage Type Search
The system must then determine from which storage type the material should be removed. You define this information in the storage type search table. For more information about how entries are defined in this table, see the section on defining the storage type search sequence under Strategies in the Implementation Guide for Warehouse Management.
In the storage type search table, you can define a search sequence with up to 30 storage types. (Make sure that you enter an A for stock removal in the column Activity.) The storage type list is constructed hierarchically, which means that the system looks for the material in the first storage type first, then in the second storage type, and so on. The entry *** for the storage type means that the system searches in the entire warehouse for the oldest stock. The table entry that the system uses for this search depends on the material being removed from storage.
You can group materials together bases on a storage type indicator so that the system uses the same search sequence and removes materials from the same storage type or types. To implement this you define:
A storage type indicator in the material master record (in the Stock Removal field)
A storage type indicator in the storage type search table (in the TyInd field)
Storage Bin Search
Once the storage type has been determined, the system then searches within the storage type to find an appropriate storage bin from which the material can be removed. 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 picking strategy.
User-Defined Strategies
To use user-defined strategies, you must select the User Exit Active field in the Stock Removal Control section of the appropriate storage type record. For instructions, see the section on Developing Function Extensions in the Implementation Guide for Warehouse Management.
