Introduction
As a Production consultant I have been asked many time in interview that, am I aware about EWM. So I am making this.
We can say EWM is evolution of Inventory management in SAP
Inventory Management (Storage location) -> Warehouse Management -> Extended warehouse management
Warehouse (WM) vs Storage location (IM)
In Storage location we can get how much stock we have in a location.
But in EWM we can get exactly in which location, at which place the product is exactly located (Storage bin).
Warehouses require larger spaces and are mostly located in remote areas i.e. outside the plant, where large land mass is available. It enables you to store, ship, and distribute your goods from one single location. This makes it easy for you to track and manage your inventory efficiently.
On the other hand, storage facilities are located mostly inside the plant since they need to be easily accessible to customers and for production.

Why Extended Warehouse?
In SAP WM has been overtaken by EMW. EWM has the same basic core functionalities as WM but with additional capabilities, such as labor management and internal routing. SAP originally wanted to phase out the WM module by the end of 2025.
Process flow difference - WM vs EWM
EWM also have 2 versions, Like PPDS in APO and PPDS in S4HANA.
Here I am explaining the Embedded Extended warehouse Management process
This is embedded PPDS in S4Hana version. So only one system credential is enough. Even though the EWM system will be configured as Logical system (Soul) inside S4Hana. So the transactions which are happening in ERP will be communicated to EWM logical system.
So here the warehouse number need to be created in 2 places both in ERP and EWM as like Plant and Location in ERP and PPDS. For example
To have a overview about EMW please go through Link

Main Part.
Overview on Configuration
To do EWM transaction we have the below configuration to be done at first.
1. Organization Structure
In EWM Warehouse is at the top in hierarchy.
Define the below to setup EWM system for doing transaction
1.a. Plant - OX10
The company is considered as plant. The plant I created is 1111. Please use copy plant. Other wise you may face controlling issue.
Enterprise Structure - Definition - Logistics - General - Define Plant
I would suggest you to better copy the SAP best practice plant. So that you can configure it later.
1.b. Storage Location - OX09
You can consider the place where the materials are stored as storage location. Here I created two AFS and ROD. In AFS the finished materials available for sale will be kept which is near by shipping point, so that it can be taken easily. And in ROD the materials just received will be kept and it will be near to loading and unloading point, so that it will be easy to put the materials in to racks whenever its unloaded.
Enterprise Structure - Definition - Materials Management - Maintain storage location
1.c. Shipping Point - OVXD
The place were the truck will stand & take the ordered materials to customer
Enterprise Structure - Definition - Logistics Execution - Define Shipping Point
1.d. Warehouse Number - EC18 - (This is ECC/ S4HANA Warehouse only 3 digits)
You can consider all the area, Storage location, shipping point... as warehouse.
Enterprise Structure - Definition - Logistics Execution - Define Warehouse Number
2. Assign ERP Warehouse Number to Plant and Storage Location
Here we are mapping the plant 1111, warehouse EWM and storage location ROD, AFS together
Enterprise Structure - Assignment - Logistics Execution - Assign Warehouse Number to Plant and Storage Location
3.Assign shipping point to plant
Here we have to assign the shipping point SHPP to newly created plant 1111
Enterprise Structure - Assignment - Logistics Execution - Assign shipping point to plant
4. Assign the Shipping point condition to Plant and to Shipping Point
Here we need to do the sales configuration of Shipping condition
Logistics Execution - Shipping - Basic Shipping Functions - Shipping Point and Goods Receiving Point - Determination - Assign Shipping Points
5. Assign storage location to shipping point
Here we have to assign the storage location to the shipping point
Logistics Execution - Shipping - Basic Shipping Functions - Shipping Point and Goods Receiving Point - Determination - Assign Goods Receiving Points for Inbound Deliveries
6. Define Warehouse Numbers - (This is for EWM system)
Later we create Warehouse number for ERP and now we have to create it for EWM Logical system.
SCM Extended Warehouse Management - Extended Warehouse Management - Master Data - Define Warehouse Numbers
7. Create one Business Partner in supplier
Transaction code BP, see Link to how to create. It need to be maintained in SCU.
Party Entitled to Dispose (PED) : Ownership of the Material
If EWM warehouse is connected to more that one plant then stock for those plant in EWM warehouse will get differentiated with Ref to PED
8. Create supply chain unit
SCU is Physical location i.e. Address to our warehouse.
Transaction code: /SCMB/SCUMAIN - created SCU-WEWM , Type 1008. Also you need to maintain the alternatives. Otherwise you could not assign it to Warehouse.
9. Assign warehouse numbers to SCU.
Assign the Owner, PED, SCU to the warehouse. All are BP
SCM EWM - EWM - master data - Assign warehouse numbers
10. Creating the EWM parameters related to ERP
Integration with other SAP system - Extended warehouse management - Basic settings for EWM linkage- configure EWM specific parameters
When you create the warehouse number in ERP it will automatically create this entry. Here you need to change the external WM as EWM.
11. Define Warehouse number control
Here you can define the dimensions for the warehouse and it will be populated to your bin type while creating it.
SCM Extended Warehouse Management - Extended Warehouse Management - Master Data - Define Warehouse Number Control
12. Create plant and shipping point as locations in EWM via program /SAPAPO/create_location via SE38
This will create the location (1111) and shipping point (SP_SHPP) in EWM.
13. You can check the same in /n/SAPAPO/LOC3
Shipping point will have SP in prefix
14. Define storage type
You can say warehouse starts from storage type. There are different types of storage types. All are differentiated by the storage type role.
Standard Storage Type, A - Identification Point , B - Pick Point, C - Identification and Pick Point, D - Staging Area Group, E - Work Center, F - Doors, G - Yard, H - Automatic Storage Retrieval (Material Flow Control), I - Work Center in Staging Areas Group, J - Automatic Warehouse (Controlled by MFS), K - Production Supply
You can ask why this door and staging area are considered as storage type because on these area also the materials will be stored for some time. Since these are also considered as storage types.
SCM EWM - EWM - master data - define storage type
For Normal storage type please maintain these
confirm put away , Put away complete, Delete stock identification , put away rule 4 - addition to existing stock, Confirm removal, availability group 002, Storage type role as empty
For Staging area storage type please maintain these
conf put away , Confirm removal, put away rule - General storage area, Storage type role D
For production we mostly use Production supply area.
15. Define Storage section
Storage type were further divided to section. Here I have created 2 sections per storage type
SCM EWM - EWM - master data - Storage section
16. Define Storage Bin type.
Storage sections are further divided into Bins. It can be tote, cage, pallet. So its need to be defined in system
SCM EWM - EWM - master data - Storage bin - Storage bin Type
As mentioned earlier these highlighted values coming from warehouse control number
17. Define Storage bin access type.
It will define how the bins can bee accessed. Fork lift, Manual, Reach truck, Order Picker.
SCM EWM - EWM - master data - Storage Bin - Storage bin access type
18. Define Storage bin identifiers
It will define the structure for the storage type.
SCM EWM - EWM - master data - Storage Bin - Define storage bin identifiers.
19. Define Storage bin structure
Here whatever we defined all we need to mention here
SCM EWM - EWM - master data - Storage Bin - Define storage bin structure
20. Create Storage bin - EWM Master data
We can create storage bin by following method
1.Create storage bin : /n/SCWM/LS01
2.Generate storage bin using Template
3.Upload Program - /n/SCWM/SBUP (Not shown here)
For loading the storage location we need to define bin identifiers and structure.
Create Storage bin in Mass using /n/SCWM/LS10
You can do Mass change using /n/SCWM/LS11
21. Create activity
SCM EWM - EWM - master data - Activity areas - activities- Define activity for activity area
22. Define activity area
Its Just combination of storage types.
Its an area to execute the activities , PTW, Picking , Internal movement etc.
SCM EWM - EWM - master data - Define activity area
23. Assign the storage type to activity area
SCM EWM - EWM - master data - Assign the storage type to activity area
24. Generate Activity Area from Storage Type
SCM Extended Warehouse Management - Extended Warehouse Management - Master Data - Activity Areas - Generate Activity Area from Storage Type. This will create set of sorting activity area where you need to add sorting conditions.
25. Define sort sequence for activity areas.
So this will create a sorting sequence for the storage locations grouped in the activity area.
SCM Extended Warehouse Management - Extended Warehouse Management - Master Data - Activity Areas - Define Sort Sequence for Activity Areas
27. Do sorting for Storage bins via upload program /SCWM/SRTUP
But we can do it one by one via /SCWM/SBST
Based on shorting procedure the bins are filled from bottom level to top but last stack to first stack.
28. Create staging area Group (Staging Storage Type)
We have defined the staging area Storage type and section. But it should be differentiated by this setting further. For GR we have 2 staging area and for GI we have 2 staging area.
SCM EWM - EWM - master data - Staging areas - Define staging area
Simply you can say
staging area group = staging storage type ST01/ST02 and
staging area = staging section SGR1/SGI1
29. Define Staging Area and Door Determination Groups - Optional
SCM Extended Warehouse Management - Extended Warehouse Management - Master Data - Staging Areas - Define Staging Area and Door Determination Groups
31. Create warehouse door
Here define which doors are for inbound and which are for outbound
SCM EWM - EWM - master data - warehouse door - Define warehouse door
32. Assign staging area/door determination door determination group
SCM EWM - EWM - master data - warehouse door - Assign staging area/Door determination Group to door
33. Assign the staging area door determination rule in EWM product
The stock comes from DGR1 should go to staging area ST01-SGR1 and stock from DGI2 to ST02-SGI2
SCM EWM - EWM - master data - warehouse door - Assign the staging area door determination rule in EWM product
34. Assign BP to plant
The BP is assigned to plant so that it will be fetched in next step automatically. See the disposal party here and next screenshot.
SCM EWM - EWM - Interfaces - ERP integration - General settings - Assign BP to plant
34 a. Configure Availability group for Putaway
This will be used to define the stock type on final putaway- Either F1 Received on Doc or F2 Available for sales. This can be directly assigned to storage type and process oriented storage
SCM EWM - EWM - Goods Receipt Process - Configure Availability Group for Putaway - Define Availability Group.
34 b. Define Non-Location-Dependent Stock Type
This is an additional notation to identify the stock type.
SCM EWM - EWM - Goods Receipt Process - Configure Availability Group for Putaway - Define Availability Group.
34 c. Configure Stock Type
This will define the stock type in the storage location in warehouse. Here you combine the Stock type with the availability group and the role.
SCM EWM - EWM - Goods Receipt Process - Configure Availability Group for Putaway - Configure Stock Type
35. Map ERP storage location to EWM
Here the ROD should have the availability group as 001 and the AFS should have the availability group as 002.
SCM EWM - EWM - Interfaces - ERP integration - Goods movement - Map storage location from ERP system to EWM
36. Define Number ranges
SCM Extended Warehouse Management - Extended Warehouse Management - Master Data - Define Number Ranges- Create NR for all documents and assign it respectively.
37. Assign ERP warehouse to EWM warehouse
We have to map the ERP warehouse EWM to the EWM warehouse EMW0 to guide system which is which
SCM EWM - EWM - Interfaces - ERP integration - General settings - Assign warehouse number from logical executions
38. Generate Distribution Model for Transaction Data Transfer to SAP EWM
Without this step the inbound / Outbound deliveries will not transfer between EWM and ERP
Integration with Other SAP Components - Extended Warehouse Management - Basic Settings for EWM Linkage - Generate Distribution Model for Transaction Data Transfer to SAP EWM
Once created you can check the same in BD64
39. Create material master in ERP via MM01 in storage location ROD, AFS also add additional unit of measure
check the same in APO via /SAPAPO/MAT1 in global data
40. Create the same in EWM via /SCWM/MAT1
Now create one dummy storage bin and assign it to dummy Process type and create PO, Inbound Delivery VL31N, and do the test
Create one dummy storage bin and assigned it to one process type
SCM Extended Warehouse Management - Extended Warehouse Management - Cross-Process Settings - Warehouse Task - Define Warehouse Process Type
Create one PO in ME21N (Confirmation Control Must) and Inbound delivery in VL31N.
Later in /n/SCWM/PRDI we can see inbound delivery.
If its not creating any WO then check in SMQ2 for error and correct it accordingly. Later do GR to close the cycle
Conclusion
This Blog will give you an overview on configuring EWM system.
Please comment if there are any changes. Also please guide if there are more links to read.
