Fusion Cloud ERP and quarterly updates, or another decade on Oracle E-Business Suite 12.2
Fusion Cloud ERP gets four updates a year, ready or not. E-Business Suite 12.2 has Premier Support through at least 2037, so staying put is a perfectly real option. We help teams run either one well, and move between them when there's an actual case for it.
Cohash implements Oracle Fusion Cloud ERP and supports Oracle E-Business Suite 12.2.
For Fusion we configure financials, procurement and projects, build integrations in Oracle Integration Cloud and regression-test every quarterly update before production sees it. EBS work is mostly 12.2 release update packs and keeping customizations compliant with online patching. If the business case holds, we plan the move to Fusion. Oracle lists EBS 12.2 Premier Support through at least December 2037.

Oracle Fusion ERP & E-Business Suite situations we walk into
We pieced these together from Oracle Fusion ERP & E-Business Suite situations that come up a lot. They're patterns. You won't find a specific client in them.
case file 01
EBS 12.2.9 with Demantra and a December 2026 support date
composite · not a client story
Beforethe situation
EBS 12.2.9 runs financials and order management, and Demantra drives the demand plan. Patching stalled after two failed ADOP cycles, and Demantra's Premier Support ends in December 2026.
What we dothe work
We fix the custom objects that broke online patching, rehearse an ADOP cycle on a clone and plan the RUP path to 12.2.15. In parallel, demand planning options are scored against the forecast process the planners actually run.

Fusion financials where each quarterly update breaks approvals
composite · not a client story
Beforethe situation
Fusion Cloud ERP went live last year. Since then two quarterly updates have changed approval routing and a BI Publisher report, and both times the team heard about it from users on day one.
What we dothe work
We build a regression pack around close, payments, approvals and the top reports, schedule it in the test environment after each update lands there, and review the What's New for features that change behavior.

Update problems surface in test, with time to fix them before the production update date.
How a Oracle Fusion ERP & E-Business Suite engagement runs
We don't start a step until the last one has produced something you can check.
step 01
Estate review
On EBS we look at the current RUP level, custom objects, online patching compliance and the integration list. On Fusion we look at opt-in features, extensions and OIC flows, and at how the last two updates were tested.
step 02
Update or upgrade plan
On the Fusion side, a calendar that puts a test window in front of every Oracle update date. On the EBS side, a RUP and AD/TXK patch plan that includes the custom code fixes it needs.
step 03
Rehearse
Fusion regression packs run in the test environment after each update lands there. EBS patch cycles and any migration conversions are rehearsed on clones with timings recorded.
step 04
Run and hand over
Production updates or cut-over with your team, then runbooks, the regression pack and the customization register left with the people who'll own them.
ai on oracle fusion erp & e-business suite
Where AI fits on Oracle Fusion ERP & E-Business Suite, and where it needs guardrails.
Oracle puts AI into Fusion Cloud ERP two ways: AI Agent Studio, and prebuilt finance agents like Ledger, Expenses, Payables and Payments. Embedded agents can only read what the user working with them may see, Oracle says. E-Business Suite has far less embedded AI, so on EBS the work happens around the platform.
AI agentasks for data or an action
Scoped identityonly the access it needs
MCP serverthe one door into the platform
Logged, approveda person signs off on writes
ERPOracle Fusion ERP & E-Business Suitedoes the work
AI Agent Studio calls external MCP servers, and Oracle advises JWT or client credentials for production. We looked for an official Oracle MCP server for Fusion ERP itself and couldn't source one. So we have outside agents call Fusion REST APIs through an integration user with narrow job roles. Every request is logged, and postings and payments need approval.
Prebuilt finance agents
Oracle lists Ledger, Expenses, Payables and Payments agents for Fusion Cloud ERP. They work inside Fusion's role-based security, so job roles and data access sets decide what each one sees. We review those roles and run each agent against real transactions in a test environment before production.
AI Agent Studio
AI Agent Studio lets teams build and customize agents with tools for REST APIs and MCP servers. Oracle's guidance favors REST tools for transactional ERP calls and MCP for outside services, such as pulling exchange rates. We build agents there when the logic belongs in Fusion.
Quarterly updates and agent tests
Oracle ships Fusion updates four times a year, and published the Financials 26D What's New on 18 October 2026. Agent behavior can change with any of them. So we put agent test cases in the quarterly regression pack.
EBS: AI around the platform
E-Business Suite 12.2 gets new features through updates but has little embedded AI. We use AI to document custom PL/SQL and Forms, explain ADOP patch failures from logs and map EBS data to Fusion or another target during a migration.
Where Oracle ERP sits between finance, HR and the warehouse
Fusion Cloud ERP, or EBS 12.2 for teams that stay on premises, holds the ledger, payables and procurement. Oracle Integration Cloud carries data in from HR, CRM and banks and out to the data platform, while Oracle access management controls who signs in.

due diligence · oracle fusion erp & e-business suite
Questions to ask any partner, including us.
Put these to anyone bidding on your Oracle Fusion ERP & E-Business Suite work. The ones who've done it answer differently from the ones who've read about it.
Q1
After go-live, who owns the Fusion regression pack? And how long does one run take?
An update arrives every quarter. If the pack has no owner and takes weeks to run instead of days, testing gets skipped and users end up finding the breaks.
Q2
Which of our EBS customizations fail online patching compliance checks?
Most failed ADOP cycles come down to custom objects that aren't compliant. The answer tells you how much work it takes to get back on a current RUP.
Q3
What happens to our Demantra or VCP processes after December 2026?
Oracle's exceptions table ends Premier Support for those 12.2 products in December 2026. A replacement takes longer than most teams expect.
Q4
Which customizations does Fusion cover in standard, and which need VBCS or OIC?
Customizations are where a move's real cost sits. Without a per-item view, the Fusion business case is a guess.
Q5
How many parallel closes will you run before cut-over?
Finance signs off a new ERP on reconciled numbers. One parallel close rarely covers quarter-end adjustments and intercompany.
01Should we stay on EBS 12.2 or move to Fusion Cloud ERP?
Both are defensible. Oracle lists EBS 12.2 Premier Support through at least December 2037, so staying is a supported choice. Moving makes sense when the customizations are mostly workarounds Fusion now covers, when you want to stop running infrastructure, or when the quarterly feature flow matters to the business. We score each customization before recommending either.
02How much testing does each Fusion quarterly update need?
Enough to cover the flows that would hurt if they broke: period close, payments, approvals, integrations and key reports. We keep a regression pack sized to those flows, run it in the test environment after each update lands there, and review the What's New for features that change behavior.
03What happens to Demantra and Value Chain Planning on EBS?
Oracle's exceptions table lists Premier Support for 12.2 Value Chain Planning and Demantra products ending in December 2026. If you rely on them, the planning replacement needs a decision now. Options include Oracle's cloud planning products or another planning platform.
04Why do EBS customizations break during patching?
Online patching in 12.2 uses edition-based redefinition, so custom objects must follow Oracle's development standards for it. Code written for 12.1 often doesn't. We run the compliance checks, fix what they report, and rehearse an ADOP cycle on a clone.
05How long does an EBS to Fusion move take?
It depends on modules, ledgers, countries, data volume and how many customizations need a new home. Most of the schedule goes to data conversion rehearsals and parallel close. We set the plan after the customization inventory, not before.
06Do you provide Oracle ERP engineers on contract or permanent terms?
Yes. We staff Fusion, OIC and EBS roles on contract, contract-to-hire or permanent terms, onsite in the US or nearshore and offshore.
