SAP S/4HANA Post-Go-Live Operations

Stage 5 of 5

Before hypercare ends, Allari® steps in to keep S/4HANA stable — in place before the SI leaves, so there is no gap.

Companies that wait until hypercare ends pay more to stabilize. Decide before the SI leaves.

Recognition Pattern

You're here if…

• S/4HANA is live, the SI is scaling down, and your team can't yet run it alone.
• Hypercare is ending and no support provider is in place — or the one you hired doesn't know your setup.
• New performance problems under real load: slow batch jobs, slow Fiori apps, HANA memory pressure.
• Integration errors are piling up unnoticed because nobody set up monitoring.
• Master data problems — material master, Business Partner, GR/IR — are handled with workarounds instead of fixes.
• The system "passed UAT" but real data and real users are breaking it.

Risk Assessment

What's at risk

The SI starts scaling down at Day 30 and hands over at Day 60–90. Their job ends on a date. Yours doesn't.

Hypercare ends on a date. Stability doesn't.

What usually breaks once the SI is gone:

• Open defects the SI pushed off to clear hypercare.
• Fragile integrations — iDoc, RFC, OData, and BTP flows that fail under real load.
• Reporting gaps in CDS views and SAC dashboards against the Universal Journal.
• Role and security issues from the required S/4HANA role redesign.
• Month-end and quarter-end problems testing never caught.
• Setup decisions nobody remembers on Business Partner, material master, and document splitting.
• Users still learning GUI and Fiori, creating tickets that are really training gaps.
• Slower performance — HANA memory pressure, batch jobs that took 4 hours in testing taking 8+, slow CDS views.

Allari does not implement S/4HANA. We keep it stable after go-live, close the defects the SI left, and fix integrations and HANA performance while your team learns the system.

What We Deliver

S/4HANA Basis Administration

Application server and HANA database administration — new skills that ECC on Oracle® or SQL Server never needed. HANA memory limits, column store, multi-tenant databases, and system replication for HA/DR.

SAP Fiori Launchpad Administration

Catalogs and groups so users see the right tiles, OData services every Fiori app depends on, Web Dispatcher setup, and CDS view performance as data grows.

Transport Governance for S/4HANA

The same DEV→QAS→PRD path as ECC, but with clean-core rules: changes that belong in BTP extensions stay out of the core. Planned regression testing for every feature pack and patch.

Embedded Analytics Support

S/4HANA reports through CDS views and the Universal Journal instead of BW/BI. We keep CDS views fast, manage SAP Analytics Cloud connections, and maintain the virtual data model.

Integration Monitoring

S/4HANA has more integrations than ECC: OData APIs, BTP Integration Suite, iDoc, and RFC. None monitor themselves. We watch them end-to-end, including third-party systems.

Release Management and Update Governance

S/4HANA Cloud gets quarterly feature packs and monthly patches; on-premise gets twice-yearly releases and monthly security notes. We check, test, deploy, and verify each one so the system doesn't drift.

Engagement Structure

How it works

Phase 1 — Days 1–30: Hypercare Overlap

We work alongside the SI's hypercare team, check what they hand over, and set up our own monitoring. We are ready before the SI leaves.

Phase 2 — Days 31–60: Transition Assumption

As the SI scales down, Allari takes on more tickets, plus HANA monitoring, Fiori administration, integration monitoring, and the first patch plan.

Phase 3 — Day 61+: Full Operational Ownership

Allari owns all S/4HANA support: Basis, HANA, Fiori, transports, integrations, and releases. OpenBook® shows every defect, incident, and cost.

Phase 4 — Sustained Operations

Allari did not implement SAP or replace the SI. Stage 5 applies the same idea to the new platform: a separate support team ready to take over when hypercare ends.

Where this goes next

Once hypercare ends, S/4HANA needs an accountable run model. Book a working session to define steady-state ownership.

SAP ECC - STAGE 5 POST-GO-LIVE STABILIZATION

Before hypercare ends, decide who owns day-to-day support.

The first 90 days decide whether S/4HANA pays off or becomes the next support burden. Support has to be ready before the SI leaves.

Stabilize S/4 post-go-live. Protect the ROI.

Working session: review your hypercare exit plan, ticket trends, and who will support S/4 once the SI is gone.
