Gartner expects the S/4HANA migration wave in 2021 – but when should you start preparing?

preparation for S/4HANA

When to start your S/4HANA journey?

According to SAP, more than 4,000 SAP customers are on their way to S/4HANA. Gartner expects a peak on S/4HANA projects between 2021 and 2023.

These figures don’t show the great deal of projects already running, where SAP customers are preparing their landscape and systems for their S/4HANA journey and de-risking the S/4HANA project which is in front of them.

Based on Datavard’s five guiding questions to identify the right transition to S/4HANA, there are three areas (Process changes, Data and System Landscape Optimization), you can start working on now. Below I describe just one example of a running project type that should be done prior to migration.

Customer case: Deleting company codes before the migration

The problem: The customer’s ECC system has been running for 13 years now, and has experienced several mergers and acquisitions. Because of that, there are now four company codes in the system which are not active or required anymore. Before launching the S/4HANA project, the customer would like to remove these company codes from the system. This should include master data, transactional data and the corresponding customizing.

The solution: First analysis shows that a deletion would reduce the system size by ~25%, so in this case by 1.2 TB. Datavard’s company code deletion solution is chosen for that. In a four-month project including implementation, three test cycles and the successful Go-Live the project goal is achieved. The effort on customer’s site is minimized by using automated test validation tool (Datavard Validate) to confirm the successful deletion.

Company code deletion in five steps

The Datavard company code deletion solution is a very standardized and mature offering. The main steps are as follows:

Step 1: Define company code or group of company codes which should be deleted

Step 2: An analysis algorithm identifies all corresponding master, transactional or customizing data. Some of the data can be identified directly as they have the company code information as key or non-key field in the table, others need to be identified via corresponding organizational units, like sales organization, plant, cost controlling area etc.

Step 3: Cross-checking and validating pre-selected data, and making a snap shot of system

Step 4: Starting deletion run. All identified table entries will be deleted on the database and disappear.

Step 5: Validation that no entries for any of the deleted company codes exist and the number of entries on critical tables with non-deletion company codes remains unchanged

Best time to start preparing for S/4HANA migration

This four month project helped to save on future costs on hardware and licenses. It also prepared the system for the migration. So our recommendation is to start now.
