Deploying SAP Landscape Transformation Replication Server (SLT) on a dedicated, separate instance is the recommended architecture for Central Finance. This approach decouples the replication workload from the operational source and target systems. A key advantage is the ability to connect multiple source systems or run additional replication scenarios without impacting the performance of the primary source systems (C, E). This architectural separation also simplifies maintenance and upgrades, as the SLT server has an independent lifecycle from the connected source or Central Finance systems, thus minimizing dependencies and downtime during maintenance windows (D). This deployment offers the greatest flexibility, scalability, and operational stability for complex system landscapes.

A. No RFC connection is required to source Central Finance systems.

This is incorrect. A standalone SLT server fundamentally relies on RFC connections to communicate with both the source systems and the target Central Finance system.

B. SLT has direct access to source Central Finance systems.

This is misleading. Access is remote via RFC and a database connection. The term "direct access" implies co-location, which is the opposite of a separate instance deployment.

SAP Landscape Transformation Replication Server: In the section "System Landscape and Deployment Options for SAP LT Replication Server

" the documentation states that the standalone scenario is recommended for most cases. It lists key advantages: "Flexibility to support multiple source systems and multiple target systems

" "Independent upgrade cycles for the SAP LT Replication Server and the source/target systems

" and "Reduced impact on the source and/or target systems." This directly supports options C

D

and E.

"System Landscape for Central Finance": This guide describes the recommended system landscape

showing the SLT system as a separate box. It explains that this setup "avoids any impact on the source systems" and allows the SLT server to be used for "other replication scenarios in parallel

" which validates options C and E.

3. SAP Note 2154420 - SAP S/4HANA Central Finance: Setup and Configuration: This central note for Central Finance implementation refers to the SLT Operations Guide

which details the deployment options. The recommendation for a standalone server is consistently based on minimizing performance impact on source systems (supporting option C) and allowing for independent maintenance schedules (supporting option D).
