It’s not mandatory
What is the importance of Quant number?
Whenever you do the GR, the system will generate one Quant number based on the combination of Material, Batch, and Bin.
Will the system creates any dynamic storage bins during the GR?
Yes, it is in the Purchase Order.
The outbound delivery plant for each item is defined in the order. The system can automatically determine the outbound delivery plant. Identify the highest priority outbound delivery plant in descending priority order?
Outbound delivery plant defined in Customer material information master record, outbound delivery plant defined in ship-to party master record, Outbound delivery plant defined in material master.
For Rack, Open and shelf storage types the picking strategy is FIFO.
Put way strategy for Rack, Open, Shelf, CRD and Fixed Bin is Next empty bin, Open storage, open storage, open storage and fixed bin respectively.

What happens when no storage location for picking is specified in the order item?
The system determines the storage location when it creates the outbound delivery and copies it into the delivery item.
The storage location entered in the order item is used in the outbound delivery.
The system determines the storage location when it creates the outbound delivery and copies it into the delivery item.
The storage location entered in the order item is used in the outbound delivery.
What is the goods movement status of the outbound delivery after a goods issue has been cancelled ?
Not yet started
You must always specify a batch before goods are issued. What is the solution if the delivery quantities of an item are to be taken from different batches?
In Warehouse Management
Manually in the batch split screen of the delivery item
Using automatic batch determination when creating the outbound delivery.
What is the requirement for the Purchase order items that are included when the inbound delivery is created?
They should have confirmation control key
Movements involving the Inventory Management system use storage areas that are defined as storage types in the Warehouse Management system and as storage locations in the IM system. The goods receipt for a purchase order is posted first in Inventory Management and the goods are then brought into the warehouse via a storage area, the goods receipt area. What are these storage areas called?
Interim storage area
The interim storage area plays a special role and can be generally be recognized at first glance in the standard system by their key ( which starts with a 9). These storage areas form a sort of bridge to Inventory Management. Good receipt area and goods issue area are typical examples of interim storage areas.

Where can we find exact whereabouts of a material quantity in the warehouse ?
· Storage bins
· In Warehouse Management, Storage bins are master data created either from the application menu or in Customizing.
· Based on this master data, the stock overview in Warehouse Management shows the exact whereabouts of a material quantity in the warehouse.
Some kinds of material; for example, certain fluids are not suited to interim storage in a goods receipt area. They are taken directly to the destination storage bin when they arrive (for example, in a road tanker). In this case, the receipt of the good posting in the Inventory Management should not trigger the creation of transfer requirements. How can we set this?
Special movement indicator
Sometimes a customer cancels an order at the last minute or wants to postpone the delivery until a much later time than planned. If the goods have already been picked and taken to the goods issue area, they have to be returned to storage.
What is the transaction available and what are its functions?
· Transaction LT0G
· You can return an entire delivery quantity to storage
· You can return the quantity from individual transfer order items
What are the transactions available to create a transfer order for moving partial stocks within a warehouse number?
a) LT01
b) LT10
Two transactions are available to create a transfer order for moving partial stocks within a warehouse number:
1. Create Transfer Order without Source Object (transaction code LT01)
2. Create Transfer Order from Stock List (transaction code LT10)
The followings are a questionnaire checklist which can be used as a reference for your WM implementation user requirements gathering.
