Challenge
The customer’s SAP ERP ECC system included nine company codes with the following modules:
- Finance (FI)
- Controlling (CO)
- Materials Management (MM)
- Sales and Distribution (SD)
- Human Resources (HR)
- Project System (PS)
To remain competitive and expand its capabilities, the customer decided to transition to a newer, more advanced SAP S/4HANA platform.
Solution
Supported by its expertise in SAP S/4HANA implementation, IBA Group migrated the existing corporate SAP ERP ECC system to SAP S/4HANA using the Brownfield approach and SAP Activate methodology.
Another objective was to adopt the standard functionality of SAP S/4HANA to improve business processes and extend existing features.
The project had the following two phases:
- Test conversion
- Production system conversion
Throughout the test conversion phase, the IBA Group team completed preparatory procedures, reduced project risks, and minimized system downtime.
For the production system conversion, the team performed the following tasks:
- Finished all pre-project activities, such as resolving conflicting business functions and add-ons, and configuring Customer/Vendor Integration (CVI)
- Reviewed and adjusted custom code in SAP ECC and SAP S/4HANA to comply with SAP S/4HANA architecture
- Adjusted access rights for the new system
- Completed the necessary configuration to close functional gaps in internal statistical reporting, cash management, and other areas
- Trained customer employees and created user manuals and operational documentation
- Migrated transactional and master data to fit the SAP S/4HANA data model
- Ran integration tests with the customer’s team to verify system performance and functionality.
The IBA Group team consisted of nine experts with SAP S/4HANA migration experience. The team successfully completed the project and proved its competence.
Results
- Production conversion finished ahead of schedule, with less than 24 hours of downtime for business users
- First operating periods, namely, month-end, quarter-end, and year-end closures, completed without system errors or customer support tickets
- SAP S/4HANA migration proceeded smoothly and the customer gained full access to the system’s functionality
The customer expressed satisfaction with both the project results and project execution process. It recognized IBA Group’s responsible approach and expertise and chose the company for another project, the SAP S/4HANA system transition to the Euro. Learn more about the case here.
