S/4HANA conversion · Simplification Items

Make your SI checks go green.

We resolve the MasterData_BP blocker (Customer/Vendor → Business Partner) in your ECC-to-S/4HANA conversion the way enterprise master data demands: consistency-first, secure by design, and human-in-the-loop — an AI resolver does the diagnosis, your people approve every change, and your data never leaves your landscape.

// the blocker

One red check can hold your whole go-live.

The S/4HANA Readiness Check turns your conversion into a wall of Simplification Items. Most go green with config. A few don't — and MasterData_BP is the one that turns a technical upgrade into a master-data project. It fails for two very different reasons, and telling them apart is where projects lose weeks.

framework

The BP framework isn't ready

An SP level too low to generate CVI proxy objects, half-failed proxies, missing customizing. Nothing can be created until it's fixed — and it's easy to misdiagnose as a data problem.

data quality

The data won't convert

Unmappable industry keys, placeholder countries, missing tax categories, bad characters in names, customers that are also vendors. At scale, thousands of records each fail their own way.

the trap

"RC green" ≠ "BPs created"

The check only verifies a link row exists — an orphaned link passes the gate while the Business Partner behind it was never created. We report both numbers, honestly.

// how we work

Earned in stages. You can stop at any tier.

We don't ask for broad system access on day one. We start read-only, prove the picture, and only escalate to changes when you've seen the plan and approved it. Each step is a deliberate grant — the safe default never changes on its own.

TIER 1 · read-only

Gauge

A read-only readiness assessment against your system (or a copy). Volumes, overlap, data-quality percentages, SP gate, config readiness — turned into a report you can act on.

TIER 2 · read-only

Diagnose

We read the post-processing errors, resolve every message to its root cause, and hand you a prioritized fix list mapped to SAP Notes and config — before touching anything.

TIER 3 · write-guarded

Remediate

We apply the config and data fixes and run the CVI load — dry-run first, batch by batch, each with your explicit approval. At scale, a self-resuming loader that survives restarts.

TIER 4 · read-only

Verify

Re-run the Readiness Check to RC0, clear every orphan link, and hand over a complete audit record of what changed and why — your evidence trail for cutover.

Governance is built in, not bolted on. The tooling runs inside your landscape, returns aggregates rather than records, masks any personal data before it's ever inspected, and refuses production by default. See the architecture & data-governance model →

// how it's built

Disclosed by design.

We don't ask you to trust a black box. Here is exactly how the tooling is built and where the data goes. The engine is an AI skill (the methodology) plus a Python MCP (the hands) that reaches your system only through a governance kernel and a swappable adapter — never a raw connection, never a hosted service.

The boundary that matters: every tool crosses the governance kernel (amber) before any adapter. Three of four tool families are read-only; only load/fix can write, and it stays write-guarded. Secrets live in memory only; only an aggregated report flows back up.

// how we keep it correct

Correct, not just complete.

Anyone can force a check green. The hard part of a master-data conversion is doing it so the data is consistent, the process is secure, and the result is verifiably right — with people, not a black box, accountable for every change. That is where we spend the effort.

CONSISTENCY

Integrity, not just a green tick

"RC green" can hide un-created Business Partners — the check only wants a link row. We reconcile links against the actual BP records, harmonize customers that are also vendors into one partner, and handle the match-code and buffer traps that silently corrupt names. Green means real, consistent BPs.

HUMAN-IN-THE-LOOP

People verify the accuracy

The AI does the diagnosis; humans own the decisions. Every write is dry-run first and approved batch by batch. We sample and verify converted records against source — a statistically meaningful check per account group — so accuracy is measured, not assumed. Nothing writes autonomously.

SECURITY & GOVERNANCE

Secure by design

The engine runs in your landscape and returns aggregates, not records; personal data is masked before anyone — or any model — sees it; production is refused by default; access stays least-privilege. Data residency and minimization aligned with PDPA & GDPR.

AUDITABILITY

Every change on the record

An immutable log captures who changed what, where, and when; each fix is mapped to a SAP Note or a named config change; the same read gives the same numbers. That is the evidence trail your auditors and your cutover board expect.

Field-tested, method-first. Proven on real ECC→S/4HANA conversions — from an SP-gated framework rebuild to multi-country data harmonization — the method is built to hold as the data volume grows, because it's the governance and verification that scale, not luck.

Consulting judgement, at machine speed.

An AI resolver drives the repetitive diagnosis; a human approves every change. One shop runs the SP upgrade, drives the load, and signs off the check.

01
AI-assisted, expert-governedThe resolver reads thousands of error messages and resolves each to its cause — but never writes autonomously. Every state change waits on a human.
02
Governance-firstAggregates over records, PII masked before inspection, data resident in your landscape, production refused by default. Aligned with PDPA & GDPR.
03
Honest reportingWe report the uncomfortable number too — that "RC green" can hide un-created Business Partners. You get the real state.
04
One shop, whole landscapeBASIS runs the SP upgrade, ABAP drives the load, same shop signs off. No hand-off gaps between build and run.
