By reading this article, you’ll learn:

  • How to use the SAP Readiness Check tool for SAP S/4HANA
  • Various impacts highlighted by this tool
Key Concept
SAP S/4HANA has a large effect on organizations that implement it. Areas that SAP S/4HANA affects include the data model, user procedure changes, add-on compatibility, and business processes. Organizations implementing SAP S/4HANA need information to define the impact and the way ahead, but this preparation stage could be a costly, time-consuming exercise. The SAP Readiness Check tool for SAP S/4HANA is a quick way to do a preliminary analysis on various aspects and to get a view on the possible paths – that is, whether conversion is possible or a greenfield or landscape transformation is the only option.

Many organizations working on SAP ERP Central Component (ECC) are looking at SAP’s latest offering, SAP S/4HANA, as a way to move toward the digital era. However, the move is most confusing for organizations that have been using ECC for a long time as they have established processes and specific developments around them.

The SAP Readiness Check tool is a self-service tool that provides a quick holistic analysis on your SAP system to lay the foundation stone on a journey to SAP S/4HANA. As organizations begin an SAP S/4HANA migration journey, numerous questions emerge, such as what happens to the extensive custom code and how much change management is needed. Similarly, SAP S/4HANA adoption can have other impacts also as shown in Figure 1. I explain and demonstrate the SAP Readiness Check tool to simplify the decision process for SAP S/4HANA adoption paths. I use a dummy ECC system to prepare and run this tool and demonstrate this tool’s capabilities.

This tool can be run only on your source ERP system running on SAP ECC 6.0 (any enhancement package from 0 to 8) or on SAP S/4HANA Finance (1503/1605). You can also use the tool to evaluate the readiness for various other versions of SAP S/4HANA (1511, 1610, and 1709).

First, you have to prepare your source SAP system for this tool. Because SAP Readiness Check analyzes the various impacts of business process, sizing, user interface, and other areas, it should be run on the production system or on a near copy of that to have detailed relevant analysis. You can run the tool on a development environment instead of a production run only for custom-code analysis, as usually all custom developments are first made in a development system and then managed via transport to a production system.

You need to read and ensure that the following SAP Notes are installed on your selected system:

  • 1872170 — Business Suite on HANA and S/4HANA sizing report
  • 2185390 —     Custom Code Analyzer
  • 2228460 —     Runtime of job EU_INIT, SAPRSEUB, performance
  • 2234970 —     Job EU_INIT
  • 2310438 —     SAP Readiness Check for SAP S/4HANA - Managed System
  • 2399707 —     SAP Readiness Check for SAP S/4HANA - Simplification Item
  • 2443236 —     SAP Readiness Check for SAP S4/HANA Business Process Improve
  • 2462288 —     Suite on HANA memory Sizing report - Advanced correction 8

In case you want to do a custom-code check in a separate system, then you need to apply at least SAP Notes 2185390, 2228460, 2234970, and 2310438 in that separate system.

For the purpose of simplicity, I show the extraction of data from the source system and upload that data into the SAP cloud tool for an SAP S/4HANA readiness check report. You can also generate the SAP S/4HANA readiness check report using an SAP Solution Manager system that is connected to your source system. Refer to SAP Note 2290622 to do analysis using SAP Solution Manager.
