SAP ECC to SAP S/4HANA Conversion

Every success story is a tale of constant adaption, revision and change.” – Richard Branson

In line with the very same philosophy, SAP rebuilt SAP ECC from the ground up to create SAP S/4HANA in 2015 to take advantage of SAP HANA’s performance and data analytics capabilities.

To start with a simple SAP ECC to SAP S/4HANA conversion, the foremost thing to understand is the basic difference between the two.

System Conversion in short is typically the fastest option, an approach that converts any SAP ECC 6.x system running on any database to SAP S/4HANA, preserving your existing configuration, customizations, and historical data. This approach allows a rapid technical conversion, adding innovations gradually for users.

The major teams involved in a conversion project are the Technology Team (responsible for executing the Software Update Manager(SUM) tool in all the platforms(Sandbox, Development, Quality, Dry and Production)) ; Functional Team (responsible for pre-check for Software Update Manager compatibility, Functional factory, Migration to new Finance Tables, Credit Management and Material Ledger activation, involving different Lines of Business) ; Security Team (adjustment of roles for new Fiori applications) ; the Advanced Business Application Programming (ABAP) Team (responsible for the custom code adaption, SAP S/4HANA code remediation etc.) and a Fiori Team (responsible for setting up the Fiori Launchpad and Launchpad designer).

To begin with a conversion project, we first need to discuss and decide on the data cleansing. This includes master data as well as transactional data cleansing (Cleansing historical data) based upon the customers’ statutory requirements. The data cleansing helps in reducing the database size to be converted proving beneficial to the technology team for a smooth conversion.
