Architecture（架构）¶
There are three main architectural patterns for connecting Foundry to an SAP system. All three follow the standard Data Connection architecture and make use of Data Connection agents.
Connecting directly to an SAP ERP or BW system¶
In this scenario, the Palantir Foundry Connector 2.0 for SAP Applications ("Connector") is installed directly on the SAP ERP or Business Warehouse (BW) system containing the data to be read or hosting the functions / queries to be executed.
Connecting to an SAP ERP system via an SAP SLT Replication Server¶
In this scenario, the Connector is installed on the SAP SLT Replication Server, and a Remote Function Call (RFC) connection is established between that server and the source ERP systems. Data is replicated from each source ERP table to a corresponding Operational Delta Queue (ODQ) in the SLT system based on database triggers.
Connecting to a remote SAP ERP system via a gateway¶
This scenario is applicable when the source ERP system does not fulfill the minimum requirements for installing the Connector (SAP_BASIS, the technical component version applicable to both SAP NetWeaver and SAP S/4HANA systems, version 7.4 SP5 or above). Here, the main component of the Connector is installed on a "gateway" application server that meets the minimum requirements, and an RFC connection is established between that server and the source ERP system(s). A remote agent component of the Connector is installed on the source ERP system(s), which facilitates the reading of data or the execution of functions / queries.

架构¶
将 Foundry 连接到 SAP 系统主要有三种架构模式。这三种模式均遵循标准的数据连接架构，并使用数据连接代理。
直接连接至 SAP ERP 或 BW 系统¶
在此场景中，Palantir Foundry Connector 2.0 for SAP Applications（以下简称"连接器"）直接安装在包含待读取数据或托管待执行函数/查询的 SAP ERP 或业务仓库（BW）系统上。
通过 SAP SLT 复制服务器连接至 SAP ERP 系统¶
在此场景中，连接器安装在 SAP SLT 复制服务器上，并在该服务器与源 ERP 系统之间建立远程函数调用（RFC）连接。数据基于数据库触发器，从每个源 ERP 表复制到 SLT 系统中对应的操作增量队列（ODQ）。
通过网关连接至远程 SAP ERP 系统¶
此场景适用于源 ERP 系统不满足安装连接器的最低要求（SAP_BASIS，即适用于 SAP NetWeaver 和 SAP S/4HANA 系统的技术组件版本，需为 7.4 SP5 或更高版本）的情况。此时，连接器的主要组件安装在满足最低要求的"网关"应用服务器上，并在该服务器与源 ERP 系统之间建立 RFC 连接。连接器的远程代理组件安装在源 ERP 系统上，用于协助读取数据或执行函数/查询。
