SAP EWM is a strategic answer to challenges of complex to simple warehouse operations. We can have following deployment options for SAP EWM 1) Embedded EWM on SAP S/4HANA 2) Decentralized EWM on SAP S/4HANA 3) Decentralized EWM on SAP ERP 6.0 4) Decentralized EWM on Non-SAP ERP System 1) Embedded EWM on SAP S/4HANA Which integrate only with local ERP Storage Locations, is available in two license version? Basic EWM: SAP offers the basic EWM application component with default S/4HANA license Advance EWM: To avail the advance functionalities additional licensing required Main Functionality difference between Basic & Advance EWM https://www.sastrageek.com/post/ewm-system-landscape 2/29 1/21/22, 1:04 AM https://www.sastrageek.com/post/ewm-system-landscape EWM System Landscape 3/29 1/21/22, 1:04 AM EWM System Landscape 2) Decentralized EWM on SAP S/4HANA With this deployment option SAP EWM is deployed on a separate server platform and connected to SAP S/4HANA system using RFC’s and CIF. Decentralized EWM on SAP S/4HANA is released for integration with SAP ERP system SAP S/4HANA system (with ERP role) Decentralized EWM cannot integrate to local ERP storage locations but can integrate to ERP storage locations of other clients or other system, is available in one license version. Decentralized EWM system capable to handle a higher volume of transactions and since this is on a different instance, system performance of the processes not impacted. This deployment option is highly capable to handle high performing material flow systems, big size warehouses and other automation. https://www.sastrageek.com/post/ewm-system-landscape 4/29 1/21/22, 1:04 AM EWM System Landscape Basics Configuration Settings for Embedded SAP S/4HANA 1.

However, in some application cases (for example, the availability check), it may be necessary for the user to access data in function call (RFC). In the target system using a synchronous remote these application cases, it is beneficial to use different RFC destinations with different user authorizations. By doing this, you can restrict user authorizations for executing certain actions in the logical target system to certain application cases. SPRO> SAP IMG Screen> Integration to Other SAP Components> Extended Warehouse Management> Basic Setting for Setting up the System Landscape> Assign RFC Destination to Different Application log 3.6 Setup Target System and Queue Type In this IMG activity you add the target system that you have already defined to the definition of the RFC destination for the transfer. The data transfer using the APO Core Interface is made with queued remote function call (qRFC) technology. This means that the data is stored temporarily in queues. The queue type (inbound or outbound) is controlled by the sending or determines whether the queues processing receiving system. In this step, you can set the queue type for the target system specified. https://www.sastrageek.com/post/ewm-system-landscape 15/29 1/21/22, 1:04 AM EWM System Landscape SPRO> SAP IMG Screen> Integration to Other SAP Components> Extended Warehouse Management> Basic Setting for Setting up the System Landscape> Set target System and Queue Type 4.

Basic Settings for EWM Linkage https://www.sastrageek.com/post/ewm-system-landscape 21/29 1/21/22, 1:04 AM EWM System Landscape 5.1 Configure EWM Specific Parameter You can display parameters for SAP Extended Warehouse Management, the decentralized system in which material stock is managed. The Warehouse Management system in SAP S/4HANA is activated by assigning the plant/storage location to the warehouse number. If this warehouse number is set to SAP S/4HANA with EWM, this ensure that the system manages the warehouse stock with an SAP EWM system. If you want to set up a decentralized Warehouse Management system, refer to the Customizing activity Activate Decentralized Warehouse System. The warehouse number identifies a physical warehouse structure within the Warehouse Management system (for example, SAP EWM). In addition, you can define the kind of communication with the SAP EWM system and activate the distribution of unchecked deliveries to the warehouse.

In a qRFC, the data is stored temporarily in queues. The queue type (inbound or outbound) determines whether queue processing is controlled by the sending or receiving system.
