Southern Europe
Background
The customer’s SAP ERP ECC system had nine company codes with the following modules: Finance (FI), Controlling (CO), Materials Management (MM), Sales and Distribution (SD), Human Resources (HR), and Project System (PS).
To remain an innovative company and expand its capabilities, the customer decided to transition to a more advanced and modern SAP S/4HANA platform.
Business Challenge
Our task is to migrate the corporate SAP ERP ECC system to the new SAP S/4HANA platform using the Brownfield approach and SAP Activate methodology enhanced with our unique S/4HANA experience. Another task was to make maximum use of the standard capabilities of the new system to improve the efficiency of business processes.
Solution
The project was implemented in two stages:
- test conversion
- production system conversion
We completed all the necessary preparation procedures, mitigated project risks, improved system downtime, and prepared the customer’s SAP ERP ECC system for the transition.
Afterwards, a production system conversion was carried out, during which our team completed the following tasks:
- We conducted all required pre-project activities for the conversion: corrected conflicting business functions and add-ons, configured CVI, and converted Customer and Vendor data to Business Partners and more;
- We reviewed and adjusted custom code on the SAP ECC and SAP S/4HANA end to comply with SAP S/4HANA architecture;
- We adjusted the authorization concept;
- We completed the necessary settings to address functional gaps: internal statistical reporting, cash management, and others;
- We provided training for customer employees, and prepared user manuals and operational documentation;
- We converted transactional and master data under the SAP S/4HANA data model;
- We conducted integration testing together with the customer.
The project team consisted of 9 professionals with SAP S/4HANA implementation experience.
Result
Production conversion was completed in the shortest possible time: downtime for business users was minimized to less than 24 hours. The first operating periods (closing the first month, quarter, and year) were successfully closed without system errors and raised tickets from the customer.
The transition to SAP S/4HANA was completed successfully. Now the customer has access to all innovative functions.
Acknowledging our successful cooperation and trust in the quality of our services, the customer entitled us to another project – a system currency transition to the euro.
