**SAP S/4HANA EWM 顾问 - 全面实施概览** 本课程全面概述了 SAP S/4HANA 扩展仓库管理 (EWM) 的实施过程，重点关注了业务系统和逻辑系统的配置。 **核心内容：** * **业务系统定义：** 课程讲解了如何为 EWM 系统本身以及与之连接的每个 ERP 系统定义业务系统。业务系统存储在跨系统和跨合作伙伴的文档流表中，用于确定文档所属的 ERP 系统。 * **业务系统与逻辑系统映射：** 已解释了业务系统与相应的逻辑系统进行映射的重要性。这是因为从 SAP ERP 发送到 SAP EWM 的交付文件仅包含 SAP ERP 系统的逻辑系统编号。通过此映射，EWM 可以根据逻辑系统确定业务系统，从而更新 EWM 中的仓库请求文档。 * **逻辑系统创建（嵌入式 EWM）：** 课程详细介绍了在嵌入式 EWM 应用中创建虚拟逻辑系统（dummy logical system）的步骤，以及此步骤对于建立 qRFC 通信和分发模型的必要性。此外，还指明了通过事务码 BD54 或 IMG 路径 **SAP NetWeaver > Application Server > IDoc Interface/Application Link Enabling (ALE) > Basic Settings > Logical Systems > Define Logical System** 进行创建。 * **重要提示（嵌入式 EWM）：** 即使 EWM 已嵌入 SAP S/4HANA，仍需要创建虚拟逻辑系统以建立嵌入式 EWM 与 SAP S/4HANA 之间的通信。而独立部署的 SAP EWM 系统则需要实际创建对应的逻辑系统。 * **逻辑系统分配给客户端：** 课程指导了如何将 SAP S/4HANA 的逻辑系统分配给客户端，以及可以通过 IMG 路径 **SAP NetWeaver > Application Server > IDoc Interface/Application Link Enabling (ALE) > Basic Settings > Logical Systems > Assign Logical System to Client** 完成此操作。如果 SAP S/4HANA 的逻辑系统已分配给客户端，则可跳过此步骤。 总而言之，本课程为 SAP S/4HANA EWM 的实施者提供了关于关键基础配置（业务系统和逻辑系统）的清晰指导。
A business system will define for the EWM (own business system) and for each ERP system that is connected to EWM system. The SAP EWM system stores the business system in the document flow tables of the cross-system and cross partner document flow and helps to determine to which ERP system a document belongs.Business System is mapped to their corresponding logical systems, because the delivery documents sent from SAP ERP to SAP EWM system contain only the logical system number of the SAP ERP system. The mapping helps to determine the business system based on logical system so that warehouse request document in EWM can be updated with the corresponding business system.In this step, you define a dummy logical system for the embedded EWM application. This setting is required for creating the distribution model needed for setting up the qRFC communication. The logical system can be created from Transaction BD54, which can also be accessed from IMG path SAP NetWeaver > Application Server > IDoc Interface/Application Link Enabling (ALE) > Basic Settings > Logical Systems > Define Logical System.Note: Although EWM is embedded in SAP S/4HANA, a dummy logical system still needs to be created to establish communication between embedded EWM and SAP S/4HANA. Standalone SAP EWM, however, would require you to create an actual logical system for the SAP EWM system.4. Assign the Logical System to the ClientIn this step, you assign the logical system of SAP S/4HANA to the client. The assignment can be made from IMG path SAP NetWeaver > Application Server > IDoc Interface/Application Link Enabling (ALE) > Basic Settings > Logical Systems > Assign Logical System to Client. You can skip this step if the SAP S/4HANA logical system is already assigned to a client.
