If you are starting an SAP S/4HANA or even considering implementing SAP S/4HANA there are a number of tasks that you need to perform to ensure it is a success.
SAP provides documentation to cover off the functionality within SAP S/4HANA and produces a document called the Simplification List that provides details of the various changes that have occurred compared to SAP ECC.
Within the On-Premise version of SAP S/4HANA a number of SAP Transaction codes have been removed, improved or replaced compared to SAP ECC. Reviewing this document and understanding the changes that are required for your specific system usage will enable you to have a better view of the changes that will be required. Without this information it can be hard to plan the project or to understand the scale of the effort that will be required. Lastly, without this information you cannot understand the level of business change required or the business benefits that you can achieve with SAP S/4HANA.
To speed this process up we went through the 270-page Simplification List document and compiled a list of all affected transaction codes. Using Google Sheets as an Odata service, we built a simple SAP Fiori app that allows a customer to review their current list of SAP ECC transaction codes that they currently use and see which particular ones require additional attention. Here is a useful post on how to use Google Sheets as JSON.
By using this SAP Fiori app, you can clearly see which transaction codes have been impacted by SAP S/4HANA with further information around the changes that you should make. By importing in your current list of SAP transaction codes you can compare them against the master list of impacted transaction codes.
Have a look at the video below which provides an overview of how the tool works.
