Audit-ready test data for an ERP programme
Every ERP migration, upgrade and analytics project needs data that behaves like the production system and is not the production system. The usual routes are a masked copy of production, which needs the copy and the permission and inherits whatever the source contained, or hand-built test data, which never has enough depth to break anything interesting.
A world here is built from accounting rules, not sampled from a source. No seed dataset exists at any stage, so there is nothing to anonymise, nothing to re-identify, and no extract request to file. The output contains no personal data about real people, which is usually the shortest privacy review a project ever has.
Seven cycles run on three platforms: procure to pay, order to cash, cash and bank, record to report, payroll, inventory and fixed assets. Every foreign key resolves, every document balances, depreciation ties to the asset subledger, statutory tax posts through the ledger with a filing summary derived from the posted lines, and the bank statement mirrors the operational payments with a per-item reconciliation. Ten jurisdictions set the currency, the accounting framework, the tax treatment and culturally appropriate master data.
One seed generates the same business reality twice, once on the classic SAP architecture with separate header and line-item tables and once on the S/4HANA Universal Journal. That is the pair a migration test actually needs: identical facts, two structures, so a reconciliation or a report or a model can be checked across the change rather than across two unrelated datasets. Mainstream SAP ECC support ends December 31, 2027, which is why that pair keeps coming up.
The same seed and configuration regenerate the package byte for byte, and a certificate records the SHA-256 of every file. A test that passed last month can be re-run against the identical data this month, so a difference in the result is a difference in your system rather than a difference in the fixture.
This is data and a hosted environment to read it in, not an ERP system. Nothing can be configured, posted or interfaced. The environment is read-only by design, it carries no authorisation objects or security log, and the record-to-report overlay is a separate accounting layer that is not re-consolidated with the operational subledgers, so the trial balance ties to the general ledger journal layer and never to the payables documents. Those limits are stated on the integrity screens inside the product rather than discovered later.
