Highlighted in previous blogs http://scn.sap.com/community/s4hana/blog/2015/11/05/hana-journey-and-features-of-scm-products-in-s4-hana-simple-logistics and http://scn.sap.com/community/s4hana/blog/2015/11/19/sap-s-road-map-for-supply-chain-solution-with-s4-hana-and-its-expected-benefits on the advantages and SCM applications being natively integrated in digital core of S/4 HANA (S4H). This blog is very specific to EWM integration with S4H.

 

It appears from below SAP slide (though stated as Labs preview) that EWM will be embedded in digital core of S4H in On-premise edition of 1610 release i.e functionalities of EWM will be made available in digital core and there is no need for running EWM as a separate application.

Advantages will be

 

  • Master data and transaction data need not be transferred between the systems and CIF and q RFC connections are not needed (Reducing TCO , inconsistency and downtime of systems)
  • Material master , business partners stored only in one system (thus reducing the data footprint )
  • Customizing objects like HU types need not be transferred to EWM  (thus reducing data footprint , inconsistency and complexity of the systems)
  • There will be no duplication of business documents ( Presently ECC delivery document are replicated as separate document numbers , thus reducing data redundancy and time spent in matching the documents numbers in reports etc)
  • Common maintenance / down time

 

Now , the question is whether this native integration of EWM with S4H will be relevant / beneficial for all customers or scenarios ? Answer is NOT as

 

One of the main USP of SAP EWM is its capability to operate in decentralized mode i.e both ERP (ECC or S4H) and EWM can run independent of each other i.e all Goods receipt (GR) , Goods issue (GI) and other warehouse activities like VAS etc can be performed in EWM even if the connection with ERP (ECC) is broken. All these transactions / documents get transferred / updated to ECC once the connection is restored.

So, the stand alone deployment of EWM will continue for

  • Business critical warehouse operations 
  • Risk mitigation (during migration to S4H etc)
  • Scalability for large warehouses

 

Hence, if the warehouse operations are de-centralized, then it needs to be ascertained  whether the option of native integration of EWM with S4H core should be chosen or not.

    While this blog post clearly states that EWM will no longer be required, The most updated simplification document of 1610 (p. 222) states:
    “2.1.18.1.3 Required and Recommended Action(s) The Warehouse Management (LE-WM) and the other components described above is not the target architecture within SAP S/4HANA. The (already available) alternative functionality is Extended Warehouse Management (SAP EWM) and a customer could start introducing EWM upfront to the SAP S/4HANA installation. ”

    So, is it or is it not a part of S4?

    We are an e-commerce seller and have an existing SAP landscape with SAP ECC and embedded WM. For our new warehouse we have planned to implement SAP EWM and we are thinking of what system setup would be the best for us.

    Current situation: SAP ECC 6.0 (SQL Database)

    New situation SAP ECC 6.0 (SQL Database) connected with SAP EWM (on a HANA database)

    Within the SAP EWM solution, next to material master data and business partners, we need other master data like Bill Of Material and plant specific material master data which is not standard available in EWM.

    Question: is there a possibility to implement SAP EWM within S4HANA as a decentralized system, connected to SAP ECC and what are the advantages/disadvantages of this solution?

    Hi Mirnal

    Got questions:

    1.0 Embedded EWM is fully sufficient to carry out EWM transactions without connecting EWM system?

    2.0 Embedded EWM system still needs EWM system to be connected with S/4 Hana system.

    Regards,

    Vijay M

    Hi Vijay,

    Please note the answer for your questions as below

    1st : Most of the transactions of decentarlized EWM can be carried out in embedded EWM. There are few limitations in embedded EWM e.g not all types of inspection are not yet supported in embedded EWM of S/4HANA 1610 release. Refer note 2347770 for more details.

    2nd : Embedded EWM does not need decentralized EWM to be connected to S/4HANA and that is the essence of merging (embedding) EWM in S/4HANA i.e EWM functionalities are available within S/4HANA without linking S/4HANA with stanalone or decentralized EWM.

    Hope , I am able to clarify your questions.

    With regards,

    Mrinal

    Hi Mrinal,

    embedded EWM functionalities in S4HANA are included in the same license for S4HANA or additional licences need to be considered by those customers who want to run EWM in the same instance?

    As per note 2347770,

    Embedded EWM in S/4HANA is available in two versions:

    • Basic Warehouse Management
    • Advanced Warehouse Management

    Does it means that option 1 is included in S4 license while option 2 requires additional license?

    thanks for clarification provided,
    regards

    Marco

      Hi Marco,

      yes, your interpretation is correct. Basic ewm functionality is included in S/4hana license and advanced ewm functionalities need additional license.
