Know different ways of Moving to S/4HANA

Know different ways of Moving to S/4HANA

There are two options: New implementation and System Conversion which are opted by the industries worldwide. While there is also a Bluefield Approach which involves Selective Data Transition. I would like to focus more on the below 2 approaches in this articles


0 reads

New Implementation

The first option is called New Implementation. This is where you start from scratch and decide on the level of functionality that you want to implement in your organization. There are up to three different levels-SAP Best Practice, SAP Activate or a Customized Project for example. You will also have the opportunity to activate various S/4HANA modules and applications as well as preconfigured business processes based on Best Practices from SAP. I will go into more detail about this methodology at a later stage of this blog series.

System Conversion

The second option is called System Conversion and involves converting an existing ECC system to S/4HANA (on premise or cloud). You can choose between In-Place conversion or Landscape Transformation which I will explain in further detail later in this blog series.

Recommended Timeline

  1. Transitioning to S/4HANA requires a lot of planning and testing
  2. The timeline depends on the size of the company and the industry
  3. Planning should be done in stages
  4. You need to check for compatibility of your existing solutions with S/4HANA

Conduct Feasibility Analysis

Conduct Feasibility Analysis

  1. First, learn about S/4HANA capabilities.
  2. Next, identify what aspects of your current system won't work well and need improvement.
  3. Then, decide which business processes are most important to transition first (i.e., what systems do you need up and running immediately after the move?).
  4. As part of this third stage, you should also conduct compatibility checks on all your existing solutions to make sure they will still run smoothly when integrated with S/4HANA Cloud and other new tools you want to add to the mix during the transition phase

Steps in Feasibility Study

Steps in Feasibility Study

  1. System Discovery : Locate all instances of your SAP landscape and connect them with KTern.AI's Digital Maps
  2. Process Analysis : Identify high-risk areas where changes will need to be made - such as the finance or supply chain modules - by analyzing your current business processes.
  3. Functional Mapping : Test how your existing solutions integrate with S/4HANA, and identify gaps so you know which ones to replace.

This app is LOADED with RELEVANT, HELPFUL, AND EDUCATIONAL material. It is creatively intellectual, yet minimal enough to not overstimulate and create a learning block. I am exceptionally impressed with this app!
