For conducting custom code analysis for an SAP S/4HANA conversion, the ABAP Test Cockpit (ATC) requires a central check system that contains the S/4HANA simplification database. The two officially recommended system setups for this are:

1. The target SAP S/4HANA system itself (e.g., version 1809 or higher), which natively includes all necessary check-relevant information.

2. A dedicated, standalone AS ABAP system with a minimum release of SAPBASIS 752. The S/4HANA simplification database content must be downloaded and imported into this system to enable the S/4HANA-specific checks.

These systems can then connect to the source SAP ECC system via RFC to perform the remote analysis.

A. An SAP ECC system is the source system being analyzed; it cannot serve as the central check system for S/4HANA readiness as it lacks the required S/4HANA simplification database.

C. While SAP Solution Manager 7.2 is built on a compatible basis, it is not a primary, recommended system for this specific task. The standard approach is using the target S/4HANA system or a dedicated AS ABAP instance.

"Set Up ABAP Test Cockpit (ATC) for custom code analysis". This guide states: "You can use either your target SAP S/4HANA system or a dedicated SAP NetWeaver 7.52 system as the central ATC check system." This directly supports options B and D.

2. SAP Note 2436688 - Prerequisites and restrictions of ABAP Test Cockpit (ATC) for remote SAP S/4HANA checks. Section "Central Check System". This note details the system requirements for the central ATC system

explicitly listing "An SAP S/4HANA system" and "An SAP NetWeaver 7.52 system" as valid options.

Section "Setting Up ATC for SAP S/4HANA Checks". This documentation outlines the architecture

stating: "The central check system for SAP S/4HANA custom code checks must be an SAP S/4HANA system or an SAP NetWeaver Application Server for ABAP 7.52 system."
