SAP EWM Stock Types

SAP EWM manages stock in stock types. System shows current stock situation on storage bin level. In every warehouse the physical stock located either in the warehouse bins or dock/staging areas. So in this way SAP EWM stocks had either “in Putaway” or “in Warehouse” with attributes like unrestricted, quality and blocked stocks. A means of subdividing storage location stock or special stock. The SAP EWM stock type gives an indication of a material’s usability.

The ERP storage locations are derived for different purposes of stocks availability like AFS (available for sale-goods available), ROD (received on Dock-goods in putaway). Based on our business requirements we can also configure storage location for cross-dock stocks and Returns.
Let’s look at stock type from bottom of the warehouse system into Storage location of ERP storage location as below
Product quantity in a bin with stock type,
Bin contains Storage type,
Storage type contains availability group plus non location stock type,
Availability group is linked to a storage location in ERP for every warehouse number
Now we can go configuration steps required for SAP EWM Stock Type

Define stock type in IMG  LIME application setting.
Define Stock types for each Warehouse in IMG Masterdata for a product
Define Availability group for putaway in GR process for putaway
Define non location dependent stock type,
Link stock type with availability group plus non location dependent.
Assign available group to Storage type
Map Storage Locations from ERP System to EWM in IMG Interfaces/ERP integration/GM

see below mapping

Storage location – availability group – non-location dep. stock type – stock type

Example:

ROD                   – 001                    – FF (free stock)                       – F1

AFS                   – 002                    – FF                                                 – F2

ROD                   – 001                    – QQ (quality stock)                  – Q3

 

Define SAP EWM Stock Type in IMG LIME application setting.

IMG> SCM Basis>Logistics Inventory Management Engine(LIME) >Application Specific setting> Determine Stock Type.

There are six stock types in standard Customizing for SAP EWM but you can configure your own stock types for you

F1: Unrestricted-Use in Putaway, Q1: Stock in Quality Inspection in Putaway, B1: Blocked in Putaway

F2: Unrestricted-Use Warehouse, Q2: Stock in QI in Warehouse and B2: Blocked Warehouse

Define SAP EWM Stock types for each Warehouse in IMG Masterdata for a product

Next Maintain SAP EWM Stock types for your Warehouse in IMG>EWM>MasterData>Product>Define Stock Types

you define the possible stock types in your warehouse number. You must assign all stock quantities managed in the warehouse to a stock type, and you can also define the stock types to meet your own requirements.

Define Availability group for putaway in GR process for putaway

EWM-stock-type-configuration

Define Availability group for putway in GR process in IMG>EWM> Goods Receipt Process>Configure Availability group for Putway.

you define the availability of the product, dependent on the storage type. The system maps the availability of a product using the stock type.

SAP recommends the following: In the final storage type, set the availability group to Mandatory

In the storage type in which you post goods receipts for deliveries, do not set the availability group to Mandatory. This enables you to post goods receipts if the stock has a stock type that does not belong to the storage type. For example, you have assigned the goods receipt zone (GR zone) to the availability group 001. The delivery item has stock type F2, which belongs to availability group 002. You can only post the goods receipt to the GR zone if the availability group is not mandatory. The system only performs an automatic posting change (for example, from F1 to F2) if:

The source and destination storage types have different availability groups.

The availability group is mandatory in the destination storage type.

The stock type in the source storage type does not belong to the availability group for the destination storage type.

Location-Independent Stock Type

Defines the quality (unrestricted-use, in quality inspection, blocked) of a stock, regardless of the availability group of the storage type.

The location-independent stock type is assigned in Customizing for Extended Warehouse Management (EWM) to an EWM stock type, and is used for the following functions:

Determining the subsequent stock type for a transfer between two storage types that belong to different availability groups.

Defines the quality (unrestricted-use, in quality inspection, blocked) of a stock, regardless of the availability group of the storage type.

Determining the subsequent stock type for a transfer between two storage types that belong to different availability groups.

Dependencies : The location-independent stock type points uniquely to one stock type in the SAP ERP system:
FF: Unrestricted-use stock
QQ: Quality inspection stock
BB: Blocked stock
RR: Returns blocked stock (non-valuated, not visible in SAP APO)
The SAP ERP system only recognizes the above stock types. You can define other location-independent stock types in EWM, if you do not need to communicate them to the ERP system.

Mapping between SAP EWM stock type and ERP stock type

Dependencies

The location-independent stock type points uniquely to one stock type in the SAP ERP system:

FF: Unrestricted-use stock, QQ: Quality inspection stock, BB: Blocked stock, RR: Returns blocked stock (non-valuated, not visible in SAP APO)

The SAP ERP system only recognizes the above stock types. You can define other location-independent stock types in EWM, if you do not need to communicate them to the ERP system.

See below example of creating Returns new storage location as “RETN” with availability group “RET” with stock type like as “Z2” plus “FF” as non-Dep stock typemap-ERP-EWM-stock-type

 

 

 

 

EWM-stocktypes-link-avlgroup

 

 

 

Storagetype-availability-group

 

 

Bin-stock-type

 

 

 

 

 

 

 

 

 

 

 

 

 

 

In general, Stock type Role is empty for the storage types. I only see some one configure stock type role example as scrapping stock would ensure that Extended Warehouse Management (EWM) automatically posts the goods to scrap stock when they are moved to the scrapping area.

See below link here how we can use stock type role can be used 

I could not able to get the help.sap documentation links here  but would like to add as and when i find any good link from SAP help portal.
