S/4HANA migration:
We make sure your numbers add up
During migration to SAP S/4HANA, test loads, error logs, mapping lists, and endless Excel spreadsheets accumulate. Bissantz creates clarity—as the data analytical supporter of your SAP project.
reliably secure data quality before go-live
reporting continuity despite new SAP structures
support instead of additional burden for your project team
New SAP world with reliable figures
S/4HANA transformation with dependable numbers instead of tedious touch-ups after go-live
The migration to S/4HANA is a technical project: new chart of accounts, business partner concept, ACDOCA as Universal Journal. Your SAP consultants have their hands full with this. Meanwhile, the numbers tend to stay behind. Error logs that no one evaluates. Mapping lists with thousands of lines that someone should “quickly check.” Prior-year comparisons that are no longer available after go-live.
The auditor wants comprehensive documentation, the CFO their usual report—but this frequently becomes a challenge during and after an S/4HANA conversion. This is precisely where Bissantz consulting comes in: We evaluate mock loads, validate mappings, and deliver reconciliation reports—so you can be sure your numbers are correct.
No transparency with mock errors?
The Migration Cockpit shows errors individually in the web UI. Click through 1,500 hits individually? Unrealistic. The consultant prioritizes by gut feeling, you have no independent view.
Our answer: A dashboard from cockpit logs: error clusters, Pareto, trend across mock cycles. Rolled out in one to two days.
No reliable balance reconciliation?
Reconciling old vs. new balances using an Excel sample? In a greenfield project with a new chart of accounts and ACDOCA, this approach is dangerously flimsy—and auditors are increasingly asking for system-based evidence.
Our answer: A balance reconciliation cockpit across all aggregation levels, documented in an auditable manner. Multidimensional reconciliation is DeltaMaster’s specialty.
No overview of mapping risks?
Mapping sheets with 5,000 rows, “just a quick glance”—without knowing which documents are affected. Greenfield completely restructures the master data.
Our answer: Each mapping line enriched with transaction volume: “Account X on Y involves 12,450 documents and €2.3 million.” Plus: Which master data has been inactive for years?
No comparability after go-live?
Pull prior-year comparison after go-live—but the old structures no longer exist in S/4HANA. The CFO wants the usual report on the first of the month and sees gaps.
Our answer: Historization concept in the reporting layer: old data in the old logic, new data in the new logic, a mapping bridge in between. Both views available at the push of a button.
No clarity about reporting requirements?
Three weeks before go-live, it becomes apparent that the standard reports from the legacy system cannot be replicated exactly in S/4HANA. The consultant no longer has any budget left for this.
Our answer: Reporting inventory in the early phase: Which reports, who uses them, which fields does S/4HANA need? This becomes the requirements list—we are the voice of the business.
No overview during cutover?
The cutover weekend coordinated with Excel and WhatsApp. If one thing goes wrong, you lose track of everything—and no one knows where the project stands.
Our answer: Lean cutover dashboard from job logs (SM37) and cockpit status. One page, color concept, progress per object. That way, the weekend stays stress-free.
No transparency about data errors?
After go-live, data errors appear that no one systematically collects. Tickets are solved individually, the cause remains obscure.
Our answer: Anomaly monitoring on ACDOCA, document and master data in Power BI. Hypercare evolves into operational reporting, and then into strategic reporting.
No view of end-to-end processes?
One posting is easy to check. The resulting process chains across multiple modules are a real challenge.
Our answer: Reporting and analysis of status and document flows for test case validation.
No functioning planning solution?
The S/4HANA migration typically renders existing planning applications obsolete. There is often a gap between the decommissioning of the legacy system and the go-live, during which there is no functioning planning solution.
Our answer: Interim planning that allows you to continue planning seamlessly..
