Warehouse Stock Management

Warehouse Stock Management


In this blog we are going to discuss about warehouse stock and its components.


Warehouse Stock management is the way of organising stock flows in the warehouse. It is highly important for the competitiveness of companies. It must be primarily focused on having an adequate level of stock in the warehouse to competently meet customer demand at an optimal cost for the company.


Q-1: What is Quant and which data stored in a Quant?

Answer: A quant is a stock segment of a specific quantity of product with the same characteristics in one location. The Quant get generated and deleted automatically by a warehouse movement like, posting change, put-away or picking activities.

The below data is available in a quant

Location of Quant: Storage bin, Handling unit (HU) and Transportation Unit (TU)

Product and Quantity

Stock Type

Stock Usage

Batch Number

Q-2: How can display Quant Data?


We cannot display quant data in EWM in GUI like in WM

Q-3: What is table name in which Quant data stored in EWM?


Q-4: What all attributes can be change in Quant without warehouse task?


GR Date and Time


Country of origin

Certificate Number

COO and SLED can only be changed on the quant if batch management not active.

Q-5: What is available stock and physical stock in Warehouse Monitor?


Physical Stock: Physical Stock shows total that is available in warehouse and data is shown for each quantity individually.

Available Stock: Available Stock is the stock for which warehouse tasks can be prepared if required.

Q-6: Which Stock Types are present in EWM?


B5 — Blocked stock in Put-away

B6 — Blocked Warehouse

C3 — Customs Quality in Put-away

C4 — Customs Quality in Warehouse

C5 — Customs Blocked in Put-away

C6 — Customs Blocked in Warehouse

F1 — unrestricted-Use in Put-away

F2 — Unrestricted-Use in Warehouse

Q3 — Stock in QI input-away

Q4 — Stock in QI in the warehouse

S5 — Scrapping from Put-away

S6 — Scrapping from Warehouse

Most of the stock types in are in pair in EWM as its makes use of Storage locations and map them with EWM Stock Types

Q-7: What is an availability group in EWM?


Availability Group

The availability group is an attribute of a stock type and represents a storage location linked to a warehouse.

For example, stock type F1 in warehouse W001 is assigned to availability group PL01/0001 and is used to manage unrestricted use stock in plant PL01 and storage location 0001.

You configure availability groups in Customizing for Extended Warehouse Management under Configure Availability Group for Put-away.

You assign availability groups to storage locations in Customizing for Extended Warehouse Management under Map Storage Locations from ERP System to EWM.

If the warehouse is linked to several storage locations, you can assign an availability group to the warehouse process type in Customizing for Extended Warehouse Management under Define Warehouse Process Type. The system uses this availability group in an inbound process to determine the stock type of the stock on the goods movement bin of the warehouse request. Without this setting, the system determines the stock type from the availability group linked to the storage location of the delivery item from Logistics Execution.

Stock types in EWM and Plant/Storage location in ERP are linked via availability groups.

First we need to define availability group for warehouse

Q-8: Which Stock Type Role are present in EWM?


Normal/Unrestricted Stock, Blocked Stock, Quality Stock, Return Stock, Scrapping Stock etc.

Q-9: What is the link between Stock Types and Storage Types?


We can assign an availability group to the storage type and based on that whenever a Warehouse Task (WT) is confirmed for the Storage Type stock type will change.

If the mandatory option is checked, its means whenever stock is moved from other availability groups, the stock transfer will happen automatically in back ground

1.     Storage Type: 0010 (High Rack Storage Type)

Q-10: What is an owner in EWM how it can use in EWM?


An owner is a business partner that represents the party of the organization that owns the stock.

It is useful during the consignment process, when order from an external vendor, then goods will remain the property of the external vendor, and later on, we can do the posting change to move stock from vendor to own valued stock.

Q-11: What is the party entitled to dispose of and how is it useful in EWM?


Party entitled to dispose is a business partner that represents the party that is entitled to dispose of the warehouse stock. Usually, it is business partner of the plant in which the stock is placed.

During delivery processing, party entitled to dispose comes from the ERP plant which is assign to the delivery number.

If warehouse assigned to multiple plants, stock can be differentiated based on party entitled to dispose and warehouse product master data can also be maintained separately for each plant.

Q-12: How is Batch Management activated in EWM?


First we need to activated Batch management in ERP system as well. Batch data is centrally managed, and Classes/Characteristics can be distributed to the EWM system through CIF.

To use batch management in EWM, batch management needs to be activated at the material level.

When EWM creates or changes batches, it attempts to call the ERP system synchronously to inform it about the change. If you use the default update control (blank), then the system triggers an error message if there is an error in the call (for example, if the ERP system is temporarily offline or the batch is locked). For update control values 1 and 2, EWM won’t display a direct error message and will attempt to update the batch asynchronously later. This lets you continue to work in EWM without interruption.

Q-13: What are some ERP characteristics available for batches as stock attributes in EWM?



LOBM_VFDAT (SLED and minimum shelf life)

LOBM_ZUSTD (Batch Status)

Q-14: What is documentary batch?


A special kind of batch which is not inventory managed.

Q-15: What is Serial Number Management?


It is used to uniquely trace and track a product in warehouse.

T-code: /N/SCWM/MAT1

Q-16: What are level present in EWM to activate the Serial Number?


1) Serial numbers for Document Items: Entered based on INB/OBD item type. There will be no stock visibility.

2) At Warehouse Number Level: Must be entered before GR/GI or before put-away (Provisional Serial Number). Information related to which serial numbers are present in the WH.

Q-17: What is Handling Unit (HU) and do we activate HU at IM level in order to use Handling Unit Management in EWM?


Handling Unit is combination material and packaging materials, it could have one or multiple packaging material to create a handling unit.

At least one packaging material is required to create a handling unit.

HU need not to be activated at the IM level to use handling Unit Management in EWM.

T-code: /N/SCWM/MON

Q-19: What is SLED and why it is used in EWM?

SLED stands for Shelf Life Expiration Date and it is used in Inbound as well as outbound.
