SAP EWM - Overview
SAP Extended Warehouse Management (EWM) is used to efficiently manage inventory in the Warehouse and for supporting processing of goods movement. It allows the company to control their Warehouse inbound and outbound processes and movement of goods in the Warehouse.
The main process in a Warehouse is incoming and outgoing materials, goods receipt and goods issue, fulfil customer orders, and distribution of goods. When a company doesn’t store any goods, then there is no need of Warehouse management to manage goods.
Inbound process involves storage of goods in warehouse and their location and Outbound process involves picking up the goods. Whenever a material is stored in a warehouse, it is stored in the storage bin and you can find its current location.
With the help of SAP EWM all the goods movement are controlled by a warehouse management system and provides you the tools to monitor warehouse activities. You can also manage additional functions in the Warehouse like creating a serial number, batch number, vendor management inventory, resource optimization and value added services. SAP Extended Warehouse Management allows you to not only monitor the quantity of goods in Warehouse but to manage other critical functions and delivery of goods efficiently.
SAP Warehouse Management is opposite to Inventory management. Inventory management tells the count of goods in the storage location and its physical location is unknown. Warehouse management deals with goods movement and monitoring the physical location of the goods recorded with specific documents.
SAP EWM is different from SAP Warehouse Management
SAP EWM is a part of SAP Supply Chain Management like Warehouse management system but provides more robust and advanced features to manage key activities in the Warehouse.
SAP Extended Warehouse Management is similar to Warehouse management but it provides more features like picking, put away, RF framework, Warehouse structure and more flexible options to manage the warehouse functions.
You can create new elements like an activity area, resources, labor management and work centers in SAP EWM which were not available in WM.
SAP EWM provides more a robust solution to manage warehouse functions in an organization. It is also a part of SAP Supply Chain Management and also supports all the processes within logistics and supply chain.
SAP EWM ─ Key Features
The following are the key features in SAP EWM −
Using SAP EWM, you can control the warehouse activities like picking, posting and managing storage bin and good receipts.
You can set alert for changed data before goods receipt from EWM to the ERP system, reversal or correction of the goods receipt from EWM to the ERP system and an inbound delivery split from EWM to the ERP system.
You can perform deconsolidation of handling units which contain different products before putting them away in different storage sections.
You can determine storage concepts using slotting for products and optimize arrangement of goods warehouse automatically.
It allows you to perform executable tasks like work packages, consisting of warehouse tasks warehouse employees should perform as part of warehouse management activities.
It allows you to manage and track vehicles as well as other transportation units from the yard check-in to yard check-out, including movements and other tasks within the yard.
SAP EWM also includes storage and handling of hazardous substances and their transportation in accordance with the regulations from SAP Environmental Health & Safety EHS.
In SAP EWM, you can also plan labor times and resources more effectively and hence you can make your Warehouse efficient by managing key resource management tasks effectively.
In SAP EWM, you can use Warehouse cockpit that allows you to display warehouse key figures graphically and to evaluate or monitor activities using defined chart types.
You can use cross-docking that allows you to perform transportation of handling units across different distribution centers or warehouses till they reach final location in the Warehouse.
Deployed Options in SAP EWM
SAP EWM can be considered as deployed in an ERP server or you can also consider it as an application in the Supply Chain Management landscape.
SAP Extended Warehouse Management is integrated with ERP to access transaction and master data and use of features like slotting, availability check also requires its integration with CRM.
It is considered as a separate application and shares the same server with the SCM applications. You can also run SAP EWM in its own SCM environment which is suitable to get improved performance.
EWM Deployment Options
The following image shows the deployment options for SAP EWM −
- Figure 1 shows SAP EWM on SCM Server.
- Figure 2 shows SAP EWM as Standalone.
SAP ERP and EWM are closely integrated with each other for transfer of transaction and master data. There are two different ways of communication.
Core Interface (CIF) − Core interface is one of the common method for communication between SAP SCM system and SAP Advanced Planning and Optimization APO. Master data maintained in ERP system like customer, material and vendor which are available in ERP system are transferred to EWM system use Core Interface CIF communication.
For transaction data (inbound/outbound delivery docs), a separate integration model is used for communication. This model uses iDocs or queued remote function call RFC.
How to check various menu structure of EWM system?
Login to the SCM system and navigate to the Extended Warehouse management node in the SAP menu. You can use various transactions to manage basic functions in Warehouse management −
|Maintain Inbound Delivery||/SCWM/PRDI|
|Maintain Outbound Delivery||/SCWM/PRDO|

|Confirm Warehouse Task||/SCWM/TO_CONF|
|Warehouse product Maintenance||/SCWM/MAT1|
SAP EWM - Organization Units
In SAP ERP, a warehouse number is used to represent the physical warehouse where all the material is stored. A Warehouse number is a 3 or 4 character field in Warehouse management or EWM respectively. Warehouse numbers are created in the ERP system and to activate it, you use a combination of plant and storage location assigned to this plant with the respective warehouse number.
Types of Organization Units
There are different organization units in a Warehouse system at different levels −
Warehouse Number − Each warehouse consists of a warehouse number which is at the highest level in a warehouse management system. Each warehouse number consists of a sub structure that maps the warehouse relationship.
Storage Type − There are different types of storage where products are physically stored in a warehouse such as open storage, goods issue and goods receipt, racks.
Storage Section − This is a part of storage type and represents a group of bins with same characteristics. Commonly used storage sections are fast moving or slow moving items, etc.
Storage Bin − The Storage bins represent the physical location of storage space where the products are stored in Warehouse. They are at the lowest level of the organization structure and when you store an item in a Warehouse you need to mention its exact location.
Activity Areas − Storage bins are further categorized in this activity area. It includes activities like picking, put away or a physical inventory. As per the activity, you can assign the same storage bin to multiple activity areas.
Quant − The quantity of goods in the storage bin is represented by Quant. The quant is used for managing inventory in storage bin.
How to Create Storage Bins and Block them for Put Away?

SAP EWM - Structure Elements
In this chapter, we will discuss regarding the different structure elements that are available in SAP Extended Warehouse Management.
Types of Structure Elements
As discussed in the previous chapter, there are various organization elements in SAP Extended Warehouse Management. These elements are also known as structure elements of a warehouse system.
The Warehouse consists of the following elements in the hierarchical structure −
- Warehouse Number
- Storage Type
- Storage Section
- Storage bin
- Activity Area
The highest unit in a Warehouse is the Warehouse number and the smallest unit is a storage bin. A Storage Bin tells the exact location of a product in a warehouse.
Warehouse Number − Each warehouse consists of a warehouse number which is at the highest level in a warehouse management system. Each warehouse number consists of a sub structure that maps the warehouse relationship.
Storage Section − This is a part of storage type and represents a group of bins with the same characteristics. The commonly used storage sections are fast moving or slow moving items, etc.
Storage Bin − The storage bins represent the physical location of a storage space where the products are stored in a Warehouse. They are at the lowest level of organization structure and when you store an item in a Warehouse you need to mention its exact location.
Activity Areas − Storage bins are further categorized in activity areas. It includes activities like picking, put away or a physical inventory. As per the activity, you can assign the same storage bin to multiple activity areas.
Quant − The quantity of goods in a storage bin is represented by Quant. The quant is used for managing inventory in a storage bin.
There are different types of storage where products are physically stored in a warehouse such as −
- Open storage
- Goods Issue
- Goods Receipt
A Storage type is a four-character name and shows a physical or a logical subdivision of a warehouse. A Storage type can consist of one or more storage sections and bins. A storage type is defined by the role it is used for in a warehouse.
A storage type can be used for the following roles −
Standard Storage Type − Physical area where products are stored in a warehouse.
Identification Point − An area where products are labeled, identified or cross checked during a goods receipt process.
Pick Point − Goods are packed when a goods pick-up process is performed.
Work Center − This represents an area in the warehouse where deconsolidation, inspection or VAS processing is done.
Apart from the above mentioned, there are storage types like Yard, Doors, Staging Area and many more.
SAP EWM - Work Center
A work center in a Warehouse is assigned to a storage type and a physical unit to perform packing, deconsolidation or weighing activities. Storage type assigned to a work center has a role of the work center, pick point or pick point and identification. You can also configure more than one work center in a storage type.
A Work Center can be used for the following processes −
- Quality check
It is also possible to combine work centers into work center groups. This allows you to send individual products to a work center group.
Creating a Work Center
To create a work center, you first need to create a storage type with a role as mentioned above that will be used to show a work center. You also need to define various configuration activities related to the master data to use work center in warehouse functions.
There are various transactions that can be performed in a Work Center −
- Value added Service VAS
- Quality Inspection
- How to create a work center for packing?
- To create a work center for packing, you need information:
- Warehouse #
- Storage Type
- Inbound section
- Outbound Section
To define a work center, navigate to the Extended Warehouse management → Master Data → Work Center → Define Work Center.
In a new window, select Warehouse # and work center to copy.
Click on copy as, and this will overwrite the new work center with an existing work center.

SAP EWM - Warehouse Process Types
A Warehouse process type is used to define the activity or movement of each process in a warehouse. It deals with each warehouse process like packing, good receipt, good issue and is assigned to each warehouse task document.
For simple movements, warehouse process type defines the storage type and bin for the movement of goods. Warehouse process type is defined at the point of creation of the warehouse document or in separate step.
All warehouse process types are further grouped into warehouse process categories. Warehouse process categories are used to define the goods movement in a warehouse.
There are different warehouse process categories that are predefined in the EWM system −
- Stock Removal
- Internal Movement
- Goods receipt posting
- Goods issue posting
- Physical inventory
- Cross Line putaway
How to Create a Warehouse Process Type for Picking?
To create a Warehouse Process Type for Picking, navigate to EWM → Cross Process Settings → Warehouse task → Define warehouse process type.
You can then select warehouse process type to copy. Click on Copy button at the top.
In stock/putaway removal section enter the storage bin and type and click Enter.
To save the warehouse process type, click on the save icon.
SAP EWM - Selling and Receiving Goods
This involves goods shipping and receiving and they are stored in a warehouse. Receiving goods process starts in the ERP system when a purchase requisition is detected and purchase order is created. A purchase order consists of the quantity of material and store and plant location. There are two ways to handle a purchase order request, which are −
First is to send the purchase order to supplier for goods delivery and once goods are received, goods receipt is posted.
Other way is to receive an announcement from supplier about the goods arrival as per purchase order request.
When a purchase order is created, you can set a CTRL key to enable notification from supplier. When you set the control key, an inbound delivery must be created on the basis of the purchase order. When a control key is set and an inbound delivery is not created, you can put the goods receipt.
An inbound delivery contains the information about the goods arrival, quantity of goods, store and plant location. The system checks the combination of the plant and storage location to check if the warehouse is in the EWM and then the system replicates an inbound delivery notification in the EWM system.
An Inbound Processing includes −
- Good receipt and optimization
- Transportation unit inspection
- Quality Inspection
- Routing of goods in warehouse
Whenever you make any changes in the inbound delivery document, these changes are reverted in the ERP system. The status of the inbound delivery is updated as per goods delivery. If the status of an inbound delivery document is execution completed, it shows proof of delivery in the ERP.
SAP EWM - Maintaining Serial Numbers
Using serial numbers, you can easily track the location of goods in the warehouse. A serial number can be used to identify the vendor and receiver details who has sent and received goods in a warehouse.
A serial number is a series of characters that have been assigned to each product in the warehouse so that it remains separate and are identified in the warehouse system. You can use serial numbers up to a length of 30 characters in an EWM system. However, SAP recommends to use a maximum of 18 characters to make it compatible with the ERP system.
Types of Serial Number Profiles
To assign serial numbers to a product, you use a serial number profile that determines transactions for issuing a serial number to the products.
There are two different types of serial number profiles that can be used −
Sales General Plant − This serial number profiles are used in the ERP system and must be defined to use serial numbers in the delivery documents for goods issue or receipts.
LES Serial Number − This is maintained in the product master data view.
When you click on the WM execution, you need to select serial number profile which is sent to SCM system and is used in EWM.
A serial number profile is maintained in the ERP or in the EWM system. There are four types of serial number requirement available in the system −
Serial Number for Document items − This serial number is used for returns. When a customer complains about a product and return is raised, you can perform a check if this is the same product that is supplied to him. This serial number is not used for other warehouse tasks.
Serial Numbers on warehouse number level − This serial number requirement type is used to check which serial number is available in your warehouse.
Serial number of warehouse movement − This serial number requirement type is used to know the exact storage bin information for products. Serial numbers are used in each warehouse task and must be entered before posting goods receipt or goods issue.
No Serial number requirement − This requirement type is used when some products are serialized in few of the warehouses.
Issuing a Provisional Serial Number
It is required to enter serial numbers before posting a goods issue or a goods receipt. In this scenario, you can configure the system to use provisional serial numbers.
The provisional serial numbers are 30 characters and always start with a $ sign. When you post goods receipt, provisional serial number is assigned and when you confirm putaway warehouse tasks, you must replace the provisional serial number with the real ones.
SAP EWM - Value Added Services
The Value Added Services define the product processing to be performed in a warehouse and includes activities like packing, labeling, assembling, etc.
To perform interim steps in the goods issue or goods receipt, you can use storage control to perform interim steps.
In the following illustration, you can see the process flow of the Value Added Services in a warehouse function −
Value Added Services Order
This is used to inform the warehouse employees about the work that they have to do as part of the delivery and packing specifications. A VAS order is an instruction to perform value added service for one or more products and to link delivery items to the packing instructions.
A Value added services order consists of the following components −
- Order Header
- VAS activities to be performed
- Auxiliary products (Packing material, labels, oil, etc.)
A VAS order can be printed for employee use to inform what VAS activities has to be performed and on which product.
An auxiliary product posting includes use of other products like packing material, hangers, oil, etc. and quantity of these products used to perform VAS.

SAP EWM – Direct Goods Issue Process
The goods issue process in extended warehouse management starts with outbound delivery request. When an outbound delivery document is created, this process starts in the ERP system. For items that are relevant in the EWM, delivery document is replicated in the SAP EWM system.
How is a Goods Issue Carried out?
In this SAP EWM system, goods issue is carried out because of the outbound delivery request (ODR), which is a copy of the outbound delivery document in the ERP system and carries the same number.
A warehouse process type is defined for each line item when an outbound delivery request is created. This process type is used in picking warehouse task.
For goods issue, the following things are required −
- Warehouse Process Category 2
- Activity Pick
To perform this, the system determines the source location of the goods to be picked from. To configure this, the following steps have to be performed.
- Define storage type search sequence
- Configure storage type search sequence determination table
Parameters to Perform a Storage Type Search Sequence
The following parameters are used to determine the storage type search sequence −
- Warehouse Number
- 2 Step picking flag
- Stock Removal control indicator (This is taken from the product master)
- Warehouse Process Type
- Quantity Classification
- Stock Type
- Stock Usage
- Hazard rating
How to configure storage type search in goods issue?
Navigate to EWM → Goods Issue Process → Strategies → Specify Storage type search sequence.
Click on New entries and enter the following details −
- Warehouse #
- Storage type search sequence
- Other description and press ENTER key
- Select the entry and click on Assign storage type to storage type search sequence

Stock Removal Strategies
Stock removal strategy is a method of determining storage bins for one or more products to be picked. You can customize the stock removal rule definition table in customizing for SCM extended warehouse management.
How to Create Stock Removal Rules?
Navigate to Extended Warehouse management → Goods Issue Process → Strategies → Specify stock removal rule.
When an outbound delivery request is created, EWM system does not create a warehouse task or task is created with a partial quantity, this is called as the Denial scenario.
The following are the common denial scenarios in a warehouse while processing a goods issue −
When a warehouse task can’t meet the quantity requested in the outbound delivery request, the system can be configured to raise a pick denial.
In case of stock discrepancy picked by an employee, a smaller quantity as per outbound delivery and no other stock is available in the warehouse, you can set the system to execute a pick denial.
To configure EWM for pick denial, navigate to Extended Warehouse Management → Goods Issue Process → Pick Denial → Activate pick denial at warehouse number level.
In the next window, find your warehouse in the table and select the activation checkbox.
Click save and exit.
Waves in Warehouse for Outbound Delivery
In SAP EWM, you can combine warehouse request items and divide them into waves as per the possible criteria like activity area, route or product. Waves can be created automatically in SAP extended warehouse management system or manually using defined waves templates.
To create a wave manually, navigate to Extended Warehouse Management → Work Scheduling → Wave Management → /SCWM/WAVE Maintain Waves and click on Create.
SAP EWM - Storage Control
Storage Control is used to determine product movements in a warehouse. It is used to execute put away or stock removal process in the warehouse.
Types of Storage Control
These activities are performed as per the physical structure of the warehouse. There are two types of storage control −
- Layout Oriented
- Process Oriented
In SAP Extended Warehouse Management, process oriented storage control is executed first and layout storage control is executed to check if the put away step is possible in the warehouse layout view and also adjust the put away or stock removal as per the layout view.
How to Setup Process Oriented Storage control?
Navigate to Extended Warehouse Management → Cross Process Settings → Warehouse task → Define Process oriented storage control.
On the left side, select the external storage process step.
Click on the New Entry and enter new external process steps.
Click on the save button at the top.
Once this is created, you need to assign the external process step to storage process and warehouse #. To do this, go to Storage process definition dialog box and click on New entries at the top.
In the next window, enter warehouse #, storage process and other details and press ENTER.
Click on Assign Storage Process Step → New Entries.
Enter the new external process steps and click on save button.
SAP EWM - Deconsolidation
The deconsolidation function can be used to divide handling units across different putaway handling units. This is required when the deconsolidate handling unit contains different products and these products has to be put away in different storage sections.
This is defined under consolidation groups for storage control.
Navigate to Extended Warehouse management → Goods Issue Process → Define Consolidation Group.
When a deconsolidation is defined in EWM, it is required for the following reasons in warehouse management −
The activity areas for the products within an HU are different.
The activity areas for the products within an HU are the same, but the consolidation groups are different.
The activity areas and consolidation groups for the products within an HU are the same, but the maximum number of warehouse tasks for the HU has been exceeded.
Deconsolidation Feature − When extended warehouse performs deconsolidation, a warehouse task is created for each handling unit item, which deconsolidation takes into account.
SAP EWM - Pick, Pack, and Pass of Goods
This module is used to manage picking, packing and transportation of goods in the activity areas in the warehouse. This can be used in RF environment commonly and process flow is same as for the standard RF process. In pick, pack and pass goods are moved from activity area to activity area till it arrives at destination point in the system.
Pick, pack, and pass can be used in two ways −
- System Controlled
- User Controlled
You need a warehouse order creation rule that supports the top warehouse order creation for the pick, pack, and pass process. The creation categories for this are −
For the system-driven option, the sequence of the warehouse orders in the top warehouse order is determined according to the sort sequence of the assigned in the configuration settings for joining the activity areas.
For the user-driven option, the sequence is manually determined during the execution, which means it can also be done by the Material Flow System (MFS).
SAP EWM - Replenishment
Replenishment is defined as the movement of goods from the warehouse to the shipment locations. In SAP EWM, you can use predefined techniques for replenishment of storage bins. There are different replenishment control fields defined at the storage type level or storage bin level. The data for control fields can be entered manually in the system or you can use slotting process to define these fields.
Following are the common control fields for Replenishment −
- Minimum stocking quantity
- Maximum stocking quantity
- Replenishment quantity
After the replenishment control data has been entered or determined, replenishment processing can begin. The replenishment control type is assigned to the storage type in Customizing. Some of the replenishment control types require additional settings in Customizing.
Types of Replenishment
Following are the different types of replenishments in SAP EWM.
Planned Replenishment − Planned replenishment can be performed either interactively or in the background. The system calculates the replenishment in accordance with the defined minimum quantity and maximum quantity. Replenishment control is triggered when the stock is less than the minimum quantity.
Order Related Replenishment − Order related replenishment is performed when stock figure is less than required quantity. The system rounds up the replenishment quantity to a multiple of minimum replenishment quantity. The maximum quantity can be exceeded and order related replenishment can be performed in the background or interactively.
Automatic Replenishment − The system starts automatic replenishment when a warehouse task is confirmed. Replenishment is calculated as per the maximum and minimum activity.
Direct Replenishment − Direct Replenishment is started during a pick denial and is only possible for fixed bin scenario. The system calculates replenishment as per maximum and minimum quantity. Direct replenishment is performed by picket and it assumes zero storage bin quantity.
How to Perform a Planned Replenishment?
The first step is to assign one fixed bin to your product. Go to Extended Warehouse Management → Master Data → Storage Bin → Assign fixed storage bins to products.

SAP EWM – Expected Good Receipts
Expected receipts are used to create inbound deliveries. You can also create a goods receipt in the EWM system without an inbound delivery.
Advantages of Using a Good Receipt
This process occurs in the EWM system only.
If your ERP system is down, you can still execute the expected goods receipt in EWM. An expected goods receipt is based on the data in production order, so it can be used as a preview of the goods receipt.
This process requires two documents to be used in the EWM system, which are −
- Notification Expected goods receipt
- Expected goods receipt
These documents can be created and transferred using the following two methods −
Push Scenario − The process is triggered in ERP by executing the report /SPE/INB_EGR_CREATE.
Pull Scenario − The process is triggered in EWM by executing the report /SCWM/ERP_DLV_DELETE.
Create a Document for Expected Goods Receipt in EWM
Go to EWM → Delivery Processing → Inbound Delivery → Expected Goods Receipt → Generate or delete expected goods receipt
Enter warehouse #. Then go to special selection parameters, go to Production number and enter the number there.

- Transportation cross docking
- Merchandise Distribution
- Push deployment
- Pick from goods receipt
- Opportunistic Cross docking
Performing Opportunistic Cross Docking
This is the only cross docking method that doesn’t require any other application or system. By using a product group and product group types in the master data, you can control the method by product.
Create a purchase order and a sales order with the corresponding delivery documents. Post the goods receipt and move the required quantity directly to the GI-Zone.
The next step is to create the inbound delivery.
To do this, go to Easy Access Menu of your ERP system: Logistics → Logistics Execution → Inbound Process → Goods Receipt for Inbound Delivery → Inbound Delivery → Create → Single Documents
