Q&A in Class (2025-03-28) EWM100

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Question: Is this possible to have S/4HANA integrated to distributed S/4HANA with TM and also integrated to another distributed S/4HANA with EWM ?

Answer: The option for Distributed EWM and Distributed TM seemed to be possible according to Experts on SAP Community. ALSO for the case if the Distributed TM system and Distributed EWM are also on different server Platforms. 

Check the Blog Posts are some of the detail findings:
https://froggysap.blogspot.com/2025/03/blog-post_24.html

Recommendations: It is best to approach SAP for Distributed EWM and Distributed TM for the BEST deployment options, upgradeability and technical difficulties if "Tight integration" between EWM and TM is expected if different S/4HANA versions.

Question: In the context of EWM, what is the difference between Stowage Type Role "D" (Staging Area Group) and Storage Type Role "K" (Production Supply) ?

Answer: It is a common practice to use Storage Type Role "K" (Production Supply) for EWM Storage Types designed as Production Supply Area (ie: Staging location for Backflushing from Production Order). In the context of SAP Extended Warehouse Management (EWM), a Production Supply Area (PSA), which corresponds to a storage type role "K" (Production Supply), is used for staging materials for production, while a staging area group (storage type role "D") serves as an interim storage area for goods before further processing, such as loading or unloading. 

  • Storage Type Role "K" is "interim" storage area before Backflush (GI) to the Production Order.
  • Storage Type Role "D" is "interim" storage area as GR Area to MM Purchase Order Inbound Delivery before Final Putaway.
  • Storage Type Role "D" can also be "interim" storage area as GI Area to SD Outbound Delivery before Final Post Goods Issue.

Production Supply Area (PSA):

  • Definition: A PSA is a specific area within a plant or warehouse where materials are staged before they are used in production.
  • Purpose: It acts as a buffer zone, ensuring materials are readily available at the right time and place for production.
  • Function: PSAs are linked to storage locations in Warehouse Management (WM) and are defined in SAP using transaction code PK05.
  • Example: Imagine a factory floor where raw materials are stored in a central warehouse. The PSA would be a designated area on the floor where those materials are moved to, ready for use by a specific production line.
  • Configuration: 
  • You define PSAs in SAP using transaction code PK05, linking them to storage locations and work centers. 

Staging Area Group "D"
  • Definition: This is the Interim Storage Type for GR to PO and Interim Storage Type for GI Area to the Outbound Delivery. 
  • Purpose: The Interim before final Putaway and Interim before final PGI.

Question: What is Data Management and Landscape Transformation (DMLT) and is the "Migration Cockpit" the same thing ?

Answer: SAP Data Management & Landscape Transformation (DMLT) is a Collection of Services provided by SAP for data migration, while the "Migration Cockpit" is a tool within SAP used for managing data migration processes, but they are not the same thing. The "Migration Cockpit"is a tool (Fiori App) that can be used as part of the DMLT services, The Migration Cockpit can be accessed through the Fiori Launchpad

SAP Data Management & Landscape Transformation (DMLT): 
  • DMLT is a broader set of services that helps businesses manage their data and transform their IT landscapes, particularly when migrating to SAP S/4HANA or other SAP systems.
  • DMLT focuses on data migration, data quality, data integration, and ensuring a smooth transition to a new or updated SAP system. 
  • Examples of DMLT services but not limited to the following:
    • Data Migration: Moving data from legacy systems to SAP S/4HANA. 
    • Data Transformation: Converting data formats and structures to match the new system. 
    • Data Cleansing: Identifying and correcting errors and inconsistencies in the data. 
    • Data Validation: Ensuring the accuracy and completeness of the migrated data. 
    • Data Privacy and Compliance: Helping organizations meet data protection regulations. 
    • Landscape Optimization: Optimizing the IT infrastructure to support the new system. 
    • Process Redesign: Supporting business process redesign during the migration to SAP S/4HANA. 
SAP S/4HANA Migration Cockpit:
  • The Migration Cockpit is a tool within the SAP system that helps users manage the data migration process.
  • It provides a user-friendly interface for uploading, validating, and cleansing data before loading it into the SAP system.
  • Features:
    • Supports data migration from various sources, including legacy systems and external data sources. 
    • Allows users to create migration projects and select migration objects. 
    • Provides different migration approaches, such as "Migrate Data Using Staging Tables

Question: What are the Technical setup for EWM RF ?


Answer: In SAP Extended Warehouse Management (EWM), the Radio Frequency (RF) framework enables warehouse operators to interact with the system wirelessly using mobile devices like handheld scanners, facilitating tasks like picking, put-away, and inventory management with real-time data capture and validation. 
SAP provide good enough documentation as a start for "Working with Mobile RF Devices":

Question: Conversion Guide from ECC with WM to S/4HANA with EWM ?


Answer: There are some tools residing in the SPRO (Customizing) of S/4HANA system (see above) to help convert WM-customizing to EWM-customizing. However, none of these tools are Mandatory as eventually EWM works completely different from WM AND this is even so in a Brown Fields Project scenario.


There is also a Template EWM Warehouse "0001" in S/4HANA EWM Installed Based systems, which contain Template Storage Types, Storage Section, Bin Structure template, Storage Type Group, Activities Areas, Staging Areas etc. This Template Warehouse "0001" can be used to perform "Complex Copy" to the desired new EWM Warehouse, the copied dependent parameters can then be Fine-Tune based on individual EWM Warehouse Requirements.

Question: As we don't have any exercises on the Serial number for EWM, here is the following setup and demo for Materials with Serialization for EWM processing.


Answer: To use serial numbers in SAP Extended Warehouse Management (EWM), you need to determine a serial number profile for a product, assign it to the product master record, and then specify serial numbers during warehouse task creation or confirmation, depending on the chosen serial number requirement. 

Specific Scenarios:
  • Goods Receipt:
    • EWM copies the serial number from the ERP system and saves it when you make the goods receipt posting in the inbound delivery. 
  • Outbound Deliveries:
    • In EWM, you can work with predetermined serial numbers in outbound deliveries and posting changes. 
  • Printing Delivery Notes:
    • EWM automatically prints serial numbers with the delivery note of the corresponding delivery item. 
  • Monitoring:
    • To display serial numbers at warehouse number level, you can use the "Stock and Bin" functionality in the Warehouse Management Monitor. 
Using Serial Numbers in Warehouse Tasks:
  • Foreground Confirmation:
    • When confirming a warehouse task in the foreground, you can assign serial numbers manually from a list of predetermined serial numbers or by specifying them manually. 
  • Background Confirmation:
    • If confirming a warehouse task in the background, EWM automatically assigns the serial numbers known to the system, provided a complete quant removal occurs and the serial numbers are defined. 
  • Serial Number Ranges:
    • If EWM cannot display a list of serial numbers (e.g., for products with "Serial Numbers for Document Items" or "Serial Numbers at Warehouse Number Level" requirements), you can assign whole serial number ranges to a warehouse task. 
  • Handling Units:
    • If the inbound delivery contains Handling Unit (HU) data, you can change the serial number for the HU data. 
Prerequisites and Configuration:
  • Define Serial Number Profiles:
    • In the ERP system, define warehouse number-independent serial number profiles for EWM that are valid for all warehouses. 
  • Assign Profiles to Products:
    • Assign these profiles to the product master records in the ERP system using the procedure MMSL. 
  • Determine Serial Number Requirement:
    • Define which serial number requirement (serial numbers for document items, at warehouse number level, or in inventory management) EWM uses for each product. 
  • Settings in EWM:
    • In EWM Customizing, ensure the necessary settings are made for serial number management, such as defining work center layouts with the appropriate indicators for assigning serial numbers.

Question: Re-visit the process flow for Batch Determination for Outbound Delivery with EWM scenario. 


Answer: See the following link to Blog Posts for the Outbound Delivery with Batch Determination:
https://froggysap.blogspot.com/2022/06/sap-scm-ewm-batch-determine-for-ewm.html

To perform batch determination for outbound deliveries in EWM, you need to configure batch management in SAP S/4HANA SD Batch Determination conditions: 
  • Batch Determination can be done in the ERP Outbound Delivery and the batch determined can then be transferred to the EWM Outbound Delivery Order for the Picking Warehouse Task. 
  • OR can also leverage the EWM integration to determine batches based on selection criteria sent from ERP, rather than assigning batches directly in ERP Outbound Delivery. 
  • In addition, two Business Add-Ins (BAdIs) are available for you to override the batch determination setting defined in Customizing for each storage location, and to change the batch selection criteria used in the batch determination to meet your individual requirements. For more information, see Customizing for Logistics Execution under SAP EWM Integration  Cross-Process Settings  Enhancements for Batch Management.
  • If you are using SAP Extended Warehouse Management (SAP EWM), you can determine batches directly in SAP EWM instead of using batch determination in SAP S/4HANA. Batch determination in SAP EWM takes into account the warehouse layout in SAP EWM (and can be of use, for example, when optimizing the picking process). In this case, SAP S/4HANA only transfers the characteristics as batch selection criteria to SAP EWM. (However, batch determination to take into account the warehouse layout will have to be simulated first confirm whether it does work).
