AI on ECC now. Migration-safe by design.
Thousands of enterprises still run ECC, with mainstream maintenance ending in 2027 and extended maintenance to 2030. Being told every AI dollar should wait for S/4HANA is wrong — and it costs years of value. Our team has implemented and run both generations.
Your SAP ECC · untouched Mantrix · side-by-side Read-only Approved write-backOlder structures. Higher premium on people who know them.
ECC's data structures are messier than S/4HANA's — which is precisely why generic AI fails faster here, and why functional depth matters more.
Costing-based CO-PA with its value fields and derivation quirks — older, messier, and exactly where margin truth hides on ECC.
CO line items at the grain where cost behavior is actually visible — the raw material for overrun and variance intelligence.
The classic document segment: cleared items, open items, payment behavior. We read it the way your AR and AP teams do.
Pre-Universal-Journal accounting: separate ledgers, separate reconciliations. Our semantic layer resolves them into one decision view.
Value now. Easier migration later.
Decision intelligence runs against ECC as it is today — no upgrade prerequisite, no waiting for the migration program to finish.
We map what your data means — profit centers, value fields, custom logic — into a semantic layer that outlives the system it started on.
When you migrate, the semantic layer and the workflows move with you. The migration gets easier, not harder, because the meaning is already mapped.
Margin leak detection, inventory reconciliation, and settlement residual monitoring — the same production workflows we deploy on S/4HANA, running on ECC today, with human-approved write-back and a full audit trail.
Your first 30 days on SAP ECC.
One decision, one paired-expert pod, four weeks — from read-only access to a governed workflow in production.
- 1Week 1
Read-only access
We connect to SAP ECC read-only — over RFC through an agent installed in your network — BAPIs, ODP delta from classic 2LIS DataSources, and table reads, map your configuration and custom logic, and pick one expensive decision with your team.
- 2Week 2
Ground the data
The data behind that decision is grounded in the Nexus context layer and reconciled against the numbers your finance team already trusts.
- 3Week 3
Build and test
The workflow is built against your live data, with an evaluation suite from test cases your team approves and approval gates mapped to your roles.
- 4Week 4
Into production
Named approvers, the audit trail and the kill switch go live. Approved actions write back to SAP ECC, and we measure the result.
The SAP ECC data behind each decision.
- FIAccounting documents and line items (BKPF/BSEG) — open and cleared items.
- CO & costing-based CO-PACO line items and profitability segments with their value fields.
- MMPurchasing documents and goods movements (EKKO/EKPO, MKPF/MSEG).
- SDOrders, deliveries and billing (VBAK/VBAP, LIKP/LIPS, VBRK/VBRP).
- PPProduction orders and confirmations (AUFK/AFKO/AFRU).
- LE / WMWarehouse and logistics execution data.
Where SAP ECC customers start.
Margin leak detection
Leaks surfaced across costing-based CO-PA value fields and CO line items, with the documents behind each one attached.
Inventory reconciliation
Book stock reconciled continuously against goods movements, with differences flagged while they can still be fixed.
Settlement residual monitoring
Balances left behind on orders and projects after settlement, caught before they distort period results.
Do we need to move to S/4HANA first?
No. Decision intelligence runs against ECC as it is today — no upgrade prerequisite and no waiting for the migration program to finish.
How does Mantrix connect to ECC?
Over RFC, through an agent installed in your network: BAPIs, ODP delta extraction from classic 2LIS DataSources, and table reads. No changes to the ECC system.
What happens when we migrate?
The semantic layer and the workflows move with you. Because the meaning of your data is already mapped, the migration gets easier, not harder.
Is it worth starting with ECC support ending?
Mainstream maintenance ends in 2027 and extended maintenance runs to 2030. Waiting means years of decisions left as they are — and everything built now carries into S/4HANA.
Can Mantrix change data in SAP ECC without approval?
No. Write-back runs through standard BAPIs, and only after a named person approves it. Every action is recorded in Mantrix Gate, a tamper-evident audit log.
Where does our data live?
Your choice: SaaS, your own AWS account, or a VM — in every option, data stays under your governance. Mantrix Projex AI also runs as a hardened image in your AWS account, including AWS GovCloud, fully offline.
Don't park your hardest decisions until the migration.
Bring us one expensive decision on ECC. In 30 days we'll show you the workflow, the controls, and the measured result — built to carry into S/4HANA.
