What is the purpose of keeping picking area? 
What is 2 step method picking in WM? 
Can picking areas be used in 2 step picking?
 
Answer:
 
A picking area is a section within a storage type in which all picking activities are carried out in the same way. The picking area groups storage bins together from the viewpoint of picking strategies
 
For example:
 
With High rack area, you want to define group of lower bins as a picking area and these bins can be used for picking the material from that storage type. 
 
To be able to use picking areas, first define the following data in Customizing for Warehouse Management under the path:
Master data -> Define Picking Areas.
 
You can define multiple picking area in a Storage type. This will be advantage if the storage type very huge. 
 
You can split the delivery with the storage type for picking so that more than one person can pick at a time.
 
You define one or more picking areas for a particular warehouse and a particular storage type. 
 
You can also define a printer for each picking area.
 
You determine for every warehouse whether transfer orders can be split for a delivery. 
 
You can also print separate picking lists.
 

2-Step picking
 
For 2-step picking, the picking process is divided into two separate steps. You optimize the picking process by collectively removing stock from your warehouse for several outbound deliveries. .
 
With this procedure, you pick a large number of outbound deliveries or transfer requirements all together. 
 
Advantages of two-step picking include:
 
1. You remove the total amount of material required in the first step. In doing so, you minimize the total number of picking transactions necessary for picking. Stock removal and allocation are two separate warehouse processes. You create a separate transfer order for each of these steps. 
 
2.You can monitor each step of the 2-step picking process in detail at any time.
