    Hi Ekta,

    Here is what I understand by the 2 different systems:

    Logical system:

    • This is representation for your physical SAP system.
    • Usage: This is used to transfer data between 2 systems.
    • Ex: if you have a PRD system as PRDECC300. Here, PRDECC300 is the logical system. This logical system is assigned to your client ex: 100 or 300. In case of decentralized / embedded EWM, there will be 2 logical systems: 1. ECC or S/4HANA and other EWM system. Both logical systems must be defined in both systems.

    Business system:

    • This is name for your logical system.
    • Usage: This name is used for mapping logical systems to business systems.
    • Ex: if you have a PRD system and name it as PRDECC300. A business system name BS_ECC is also given to this system. This business system name BS_ECC is mapped or assigned to logical system name PRDECC300.

    Linkage:

    • Business system is mapped to Logical System
    • ERP warehouse # is mapped to EWM warehouse # via business system
    • Distribution model between ERP and EWM logical systems

    How it works:

    • When a delivery is created in ERP and sent to EWM, the delivery contains information about the logical system. Since EWM needs the business system name for warehouse requests, it gets the business system name from the logical system name.

    Let me know if you have any further questions?

    The role still stays the same as in decentralized EWM. Even though SAP has embedded EWM in S4, it still treats EWM as separate logical system. The settings mentioned above need to configured.
