2. Why use Warehouse
Management?
• To manage warehouse in an efficient
way
Inventory Management.
Space Management.
Resource Management
• To be able to deliver the customer orders or to supply the production with
needed materials without delay
• To offer variety of products, more & more assembly processes are transferred
to warehouse or distribution center
• To store large number of articles in different packaging & sizes
• Inventory management to exact bin level

4. Integration from ERP to EWM
• Usually EWM is installed on a separate system or instance, connected to an ERP
system
EWM is
EWM is
solution
via remote function calls (RFCs)
based on the SAP Supply Chain Management (SCM)
a decentralized system and interfaces have to be setup to integrate the
to ERP
•
•
• Business benefits in having a decentralized system-
Even if the central ERP is down for maintenance, the work in the warehouse
can continue
Also from a performance perspective the EWM system can be sized and
upgraded independently, and the EWM hardware can be physically located
close to the warehouse itself leading to faster response times
• The interfaces between the ERP and EWM systems are using queued RFC
(qRFC) technology for communication, for both master and application data
5. Integration between EWM and
ERP works via qRFC

6. Steps in ERP
•Activating Business Functions in Switch Framework
•Creating an RFC User in ERP
•Naming the Logical System for the Connection to SAP EWM
•Assigning a Logical System to a Client
•Specify the SAP APO Release
•RFC Destinations
•Setting the Target System and Queue Type
•qRFC Monitor Settings
•Setting User Parameters for Data Transfer
•Checking Basic Table Entries
•Extended Inbound Delivery
•Assigning Warehouse Number to Plant and Storage Location
•Assigning Shipping Points to Plants
•Maintaining Shipping Point Assignment to Plant
•Assigning Goods Receiving Points for Inbound Delivery
•Organizational Structures in the ERP System
•Defining Delivery Split by Warehouse Number
•Activate Business Configuration Sets (BC Sets)
7. Steps in EWM
•Creating an RFC User in SCM
•Naming the Logical System for the Connection to SAP ERP
•Assigning a Logical System to a Client
•Define RFC Destinations
•Maintaining Business System Groups
•Assigning Logical System and Queue Types
•Determining RFC Destinations for Method Calls in EWM
•Maintenance of qRFC Monitor Settings
•Defining a Separate Business System
•Defining the Business System
•Defining Outbound Communication
•Setting Control Parameters for the ERP Version Control
•Delivery Processing
•Defining Warehouse Numbers
•Mapping Warehouse Numbers
•Activating Business Add-Ins (BAdIs) (optional) Defining the
Transportation Group (optional) Specifying Output Format of
Product Number Checking the SAP APO Model and Planning

8. Master Data Integration
• To transfer master data from ERP to EWM you need to create and activate a CIF integration
model
• To create the integration model in ERP use T-code CFM1
•
•
•
Enter a Model Name, APO Application, and the Logical System Name of the EWM system
Select the objects that you want to include into the integration model
Then select the Select Option Buttons for the relevant object to display the selection data on the
right
pane of the screen
On the right side you then enter the selection criteria for the objects that should be included

Activity Area represents a group of storage bins that are grouped together for creating Warehouse
Orders
related to particular activities, such as picking, putaway, or physical
inventory Y
ou can assign the same bin to multiple activity areas for different
activities. New structure for EWM (did not exist in ERP WM)
11. Warehouse Doors and Staging
Areas
• Warehouse doors are the locations at which the loading and unloading activities occur
movements into and out of the warehouse
Many warehouses have multiple doors
To create warehouse door in IMG use Define warehouse door
For each door you can specify that the direction is either inbound, outbound, or both
for
•

•
12. Warehouse Doors and Staging
Areas
• Staging areas are generally physical areas within the warehouse near the doors where
the product is staged temporarily before the loading process or after the unloading process
To create staging areas in IMG use Define Staging Areas
Specify whether the staging area is relevant for goods receipt, goods issue, or both
•
•
13. Warehouse Doors and Staging
Areas
• To determine which doors are relevant for which products
– First create Staging Area and Door Determination Groups in IMG
– This Determination Group is assigned to the Product
• Also you can assign the Staging Area Group and Staging Area to the Warehouse Door
15. Work Centers
• Work Centers are locations in the warehouse where special processes occur, including
Packing, Deconsolidation, Value-Added Services (VAS), Counting, Quality Inspection, etc
To create work centers in the IMG use Define Work Center
•
17. EWM warehouse stock
Management
EWM does not maintain the ERP storage location in the EWM warehouse quant
data.
Instead of storage location, the system uses the EWM availability group code to
determine an EWM stock type.
In EWM customizing there is a table that maps the ERP Plant, storage location and
Logical system number to an availability group code.
The availability group is also the link between stock types in EWM and the ERP
plant and storage location stock. Y
ou can have different stock types in EWM for one
storage location in ERP

20. Change in Availability

If Source Storage type Availability group is different than Destination storage type
availability group, it results in corresponding Stock type change in EWM and SL-SL
