SAP ECC and AI: what the ECC AI update is, and what it requires
ECC customers are asking whether their system will get AI before maintenance ends. SAP’s answer changed in 2026, and it comes with a commercial condition. What SAP has said, what users report, and why the structure of the system matters more than the assistant on top of it.

Google Trends lists "sap ecc ai update" as the fastest-rising search related to SAP ECC over the past twelve months, up 250% worldwide1. It comes from people who run a working system, read daily that AI is changing how companies operate, and want to know whether their ERP is part of that change or an obstacle to it.
What SAP has said, in order
July 2023: cloud only. SAP's chief executive, Christian Klein, told investors that SAP's newest innovations would be delivered only in the public or private cloud through RISE with SAP. His words were: "Our new innovations will not be available for on-premise or hosted on-premise ERP customers on hyperscalers"2. Generative AI was among the innovations named3.
The reaction. DSAG's chairman, Jens Hungershausen, called it "a 180-degree turnaround from previous statements"3. In a joint DSAG and ASUG survey in summer 2024, 65% of respondents in German-speaking countries said it was important that AI be usable regardless of the SAP operating model, and 86% asked for appropriate pricing models4. SAP board member Thomas Saueressig replied that more than 800 innovations had reached on-premise S/4HANA since 2023, and that generative AI was the exception4.
May 2026: a conditional reversal. At its Sapphire conference SAP said the majority of Joule assistants and agents would become available on ECC and on-premise S/4HANA. Mr Klein described this "as an interim solution so that they can benefit from AI while they are modernizing"2.
The conditions
| Condition | What SAP has said | Source |
|---|---|---|
| A cloud move under way | For customers that have started their modernisation on RISE with SAP and committed the majority of their landscape to it | The Register2 |
| A commercial plan | Customers must sign up for the Max Success Plan | The Register2 |
| Spend moved to cloud | At least 50% of maintenance spending shifted to the cloud before Joule assistants are enabled on-premise | SAP, confirmed to CIO5 |
| Scope | "The majority" of assistants and agents; SAP has not listed which stay cloud-only | The Register2 |
| No change to dates | No plans to extend the ECC deadline beyond 2027 | CIO5 |
Read together, the offer is an incentive to sign a cloud contract, delivered as AI. An ECC customer that intends to stay on-premise, or to leave SAP, does not qualify. SAP's chief strategy officer, Sebastian Steinhaeuser, summarised the position: "To be super clear, our Joule assistants and agents are designed for cloud", and "destiny is unchanged"5.
Where customers run AI instead
The DSAG investment report for 2026 gives the clearest picture of what companies have done while waiting. Forty-three per cent of the 198 member companies surveyed had implemented AI use cases. Among those, 77% ran use cases in production with non-SAP solutions and 3% with SAP solutions; at the proof-of-concept stage the figures were 62% and 26%6.
In other words, the AI that SAP customers use in daily work already runs outside SAP. That is practical evidence for a point analysts make in the abstract. One analyst told CIO that SAP is correct that AI is hard to deliver on on-premise platforms that were not designed for it5.
Why the structure matters more than the assistant
An ECC system holds its data in structures defined decades ago and then adapted by each customer. ASUG's research describes the result: "Many organizations have built unique, business-critical processes in ECC that cannot be transferred", and 44% of its members name customisations as a barrier to moving7. ISG found that more than half of large companies say they over-customised their legacy ERP8.
An assistant added to such a system can read and summarise what is there. It cannot change the fact that customer correspondence sits in mailboxes, supplier documents in file shares and operational decisions in spreadsheets, none of them in the ERP. AI is most useful when it works across all of a company's records, and an ERP with a fixed data model and a separate AI product attached to it keeps those records apart.
This is the argument for treating the deadline as a decision about architecture. OpenLazarus, an AI lab that helps established companies become AI-native, builds the alternative: one AI and data layer that the company owns, with prebuilt CRM, ERP, email, messaging, telephony and customer service modules running on it9. People and agents work from the same records. The architecture is multi-LLM and headless, so the company is not tied to one model provider and does not rebuild when models change9. OpenLazarus says its automatic model selection reduces token costs by more than 80%, a figure of its own that has not been independently measured9.
What to do with this
- Ask SAP in writing. Which Joule assistants would be enabled for your ECC release, on what date, and under which contract.
- Price the condition. Shifting half of the maintenance spend to the cloud is a contract decision with a multi-year cost. Compare it with the figures in the guide to support after 2027.
- List where your data actually is. For three core processes, write down every system, mailbox and spreadsheet a person consults. The length of that list measures how much an ERP assistant would miss.
- Run one process on a layer you own. Connect the records for a single process, give an AI agent a defined job with approval limits, and measure the hours it removes.
- Decide on evidence. If the owned layer outperforms the assistant on that process, the route out of ECC deserves the budget.
A company that follows this sequence ends with a measured answer to the AI question, not an announcement to wait for.
Those ready to build can start in the OpenLazarus builder; those who want it built for them can talk with the OpenLazarus team.
Questions buyers ask
Is SAP Joule available for SAP ECC?
Since May 2026, partly and conditionally. SAP said most Joule assistants and agents would be offered for ECC and on-premise S/4HANA as an interim solution, for customers that have started a RISE with SAP move and sign the Max Success Plan. SAP confirmed that at least 50% of maintenance spend must shift to the cloud first.
Is SAP Joule available on-premise?
Only under the same conditions. SAP’s chief strategy officer said in May 2026 that Joule assistants and agents "are designed for cloud". SAP board member Thomas Saueressig said in 2024 that generative AI was excluded from the innovations delivered to on-premise S/4HANA.
Can AI run on top of SAP ECC without SAP?
Yes, and most customers that use AI do it that way. In DSAG’s 2026 survey, 77% of member companies with AI use cases ran them in production on non-SAP solutions and 3% on SAP solutions. The limit is that an assistant placed on top of ECC inherits its data structures.
Is SAP ECC outdated?
It is a mature system that SAP stopped developing in favour of S/4HANA, launched in 2015. It still runs the core processes of thousands of companies. What it lacks is a route to AI that does not pass through a new SAP contract.
