You use this picking technique when the picking is carried out from a randomly organized warehouse using transfer orders.

This technique has the following characteristics:

• The document used to remove the material from the warehouse is a transfer order (TO), which is created in the WMS.
• When material is transferred from the warehouse, it can be transferred from reserve storage as well as a picking area.
• The source storage bins for the material are determined by the stock removal strategy defined for the corresponding storage type.

You can use this picking technique if you require verification of the picked materials. Unlike the situation with fixed bin picking, the printed transfer order serves as a pick list for picking the materials required. The confirmation of the physical goods removal depends upon the confirmation of the transfer order. If you confirm the transfer order, the picked quantity is deducted from the storage bin and posted to the stock quantity in the interim storage type.

The stock pick can take place from various storage types (for example, from the main storage area for replenishment stock and from the fixed-bin storage area). The WMS selects the storage types and individual storage bins from which to pick the stock in accordance with the pick strategies defined for these.

The delivery is a request to WM to make goods available. You create a TO based on the delivery. The transfer order is then used as a pick list.

The figure below shows the relationship between the delivery document, the WM transfer order, and the storage bins in the high rack storage area from which the material is removed. During TO generation, the system creates a transfer order with different material numbers in which two TO items are needed for the material from item 1 of the delivery, one TO item is needed for the material from the second delivery item, and three TO items are needed for the material from the third delivery item.

You use this picking technique when you need a return verification of the materials picked. In contrast to fixed bin picking, the printed transfer order serves as the picking list for the removal of material from storage. The verification of the physical stock removal is based on the confirmation of the transfer order. When you confirm the transfer order, the system subtracts the quantity picked from the storage bin and posts it to the stock quantity in the interim storage area. The stock removal can take place from several different storage types in the warehouse (for example, reserve storage and fixed bin storage). WM selects the storage types and individual storage bins from which the stock is to be picked based on the stock removal strategies you define for this purpose.
