The need

The company ran a stable S/4HANA system on an older release that was leaving mainstream maintenance, and structural changes in the business needed new processes.

What we did

  • Upgraded to SAP S/4HANA on-premise 2023 using a shell conversion
  • Remediated custom ABAP code and discontinued the HCM component
  • Ran workshops with business users and configured improvements in finance, costing, production, sales and procurement that formed part of the upgrade business case
  • Carried out cutover and go-live on the new release

The result

Live on S/4HANA 2023 without any significant issue, with the improvements the business case promised. We now provide AMS, including RICEF developments, process changes and automation.

Questions

ECC to S/4HANA Migration, answered.

When does SAP ECC support end?
Mainstream maintenance for SAP ECC 6.0 (EHP 6 to 8) ends on 31 December 2027. Optional extended maintenance to 31 December 2030 is available at extra cost.
Brownfield, greenfield or selective: which is right?
It depends on how much process design and history you want to keep. Many companies choose a selective transition; a readiness assessment compares the options for you.

Yes. Many companies convert to S/4HANA as part of a move to SAP Cloud ERP, Private.
