SAP Process Integration (PI) and SAP Process Orchestration (PO) sit at the centre of enterprise integration architectures that took years to build. EDI exchanges, ERP-to-ERP interfaces, B2B partner connections, internal workflow orchestration — these platforms are operational-critical. And SAP knows it.
SAP's strategy is straightforward: end mainstream maintenance for on-premise PI/PO, make SAP Integration Suite (cloud-based iPaaS) the only supported path forward, and price that transition at a level that maximises SAP's recurring revenue. For organisations running large PI/PO landscapes, the migration cost runs into millions before you even factor in the subscription. Third-party support breaks that leverage entirely.
SAP PI/PO Version Timeline
SAP's integration middleware has evolved from XI through PI to PO. The current on-premise generation is SAP PO 7.5, built on SAP NetWeaver 7.5. Earlier versions have already reached end of mainstream maintenance.
| Version | Platform | Mainstream Maint. End | Extended Maint. | TPS Available |
|---|---|---|---|---|
| SAP PO 7.5 (Process Orchestration) | NetWeaver 7.5 | Dec 2027 | 2030 (+premium) | ✓ Full Coverage |
| SAP PI 7.4 (Process Integration) | NetWeaver 7.4 | Dec 2025 (ended) | Limited availability | ✓ Full Coverage |
| SAP PI 7.31 | NetWeaver 7.31 | Ended | Ended | ✓ Full Coverage |
| SAP PI 7.3 / 7.11 | NetWeaver 7.3 | Ended | Ended | ✓ Full Coverage |
| SAP XI 3.0 | NetWeaver 2004s | Ended | Ended | ✓ Full Coverage |
If you're running SAP PI 7.4 — extremely common in organisations that undertook NetWeaver upgrades in the 2017–2020 window — SAP's mainstream maintenance ended December 2025. You are now either paying for extended support at a premium, relying on Best Effort support, or both. Third-party support is the rational alternative from this point forward.
The SAP Integration Suite Migration Reality
SAP Integration Suite is the cloud-native successor to PI/PO: it includes Cloud Integration (formerly HCI), API Management, Open Connectors, Integration Advisor, and Event Mesh. The technical capability is substantial. The migration economics are brutal for large PI/PO estates.
What Migration Actually Involves
- Interface inventory: Large PI/PO landscapes commonly hold 300–2,000+ integration objects (iFlows, message mappings, value mappings, partner profiles). Every interface must be recreated or migrated to Integration Suite format.
- Migration Tooling Limits: SAP provides a Migration Assessment and semi-automated migration tools, but they handle a fraction of complex iFlows automatically. Customised mappings, ABAP mappings, and legacy Java-based interfaces require manual redevelopment.
- B2B / EDI partner re-certification: PI/PO handles EDI exchanges (EDIFACT, ANSI X12, AS2) for external trading partners. Every partner connection must be re-tested and re-certified in Integration Suite — a process that depends on trading partner cooperation and cannot be accelerated unilaterally.
- Subscription pricing shock: SAP Integration Suite is priced on message volume. Organisations processing millions of EDI messages monthly face material ongoing cost increases versus PI/PO on-premise licence amortisation.

Cost Model: SAP Enterprise Support vs Third-Party Support
SAP PI/PO is licensed per named user or per software component — annual Enterprise Support is charged at 22% of licence value. For production PI/PO environments, licence values are substantial and support costs follow. Third-party support is priced at 30–50% of current SAP Enterprise Support spend.
| Organisation Profile | SAP ES / Year | TPS Cost / Year | Annual Saving | 3-Year Saving |
|---|---|---|---|---|
| Mid-market (50–100 interfaces) | $85,000 | $30,000 | $55,000 (65%) | $165,000 |
| Enterprise (200–500 interfaces) | $220,000 | $70,000 | $150,000 (68%) | $450,000 |
| Large enterprise (500–1,500 interfaces) | $520,000 | $140,000 | $380,000 (73%) | $1.14M |
| Global (1,500+ interfaces, multi-region) | $1.1M | $275,000 | $825,000 (75%) | $2.48M |
These figures cover PI/PO standalone. Organisations that also have SAP ECC, SAP BW, or SAP Solution Manager on third-party support can negotiate a blended rate across their entire SAP estate, increasing the effective saving further.

SAP PI/PO is almost never the only SAP system in a large enterprise environment. Organisations running PI/PO typically also have:
- SAP ECC 6.0 — the transactional backbone that PI/PO integrates with
- SAP Solution Manager 7.2 — the monitoring and ITSM layer for the whole landscape
- SAP BW / BW on HANA — the analytics layer fed by PI/PO integration processes
- SAP BusinessObjects / Crystal Reports — reporting on top of BW
When all of these are brought onto a single GoVendorFree engagement, the annual cost saving against SAP's combined Enterprise Support rate typically exceeds 70%. More importantly, the operational benefit is significant: one escalation path for cross-system incidents that previously required engaging four separate SAP support queues.
Sector Profiles
Automotive and Manufacturing
PI/PO is the EDI backbone for automotive supply chains — EDIFACT DELFOR, DELJIT, INVOIC, and DESADV messages flowing between OEMs and hundreds of tier-1 and tier-2 suppliers. The complexity of these B2B trading partner relationships makes migration to Integration Suite a multi-year programme. Third-party support stabilises the integration layer while the business evaluates its architecture roadmap without SAP's renewal pressure as the forcing function.
Retail and Consumer Goods
Large retailers run thousands of trading partner connections through PI/PO — supplier order confirmations, shipment notifications, invoice reconciliation. The seasonal peak load patterns in retail make message volume-based Integration Suite pricing particularly risky. Third-party support maintains the on-premise platform and predictable annual cost through trading peaks without exposure to consumption charges.
Financial Services and Insurance
Financial institutions use PI/PO for payment file processing, reconciliation interfaces, and regulatory data flows. These environments carry stringent audit requirements — any change to the integration layer requires extensive regression testing. The stability and predictability of an unchanged PI/PO platform under third-party support is a genuine compliance advantage, not just a cost argument.
Your Four Strategic Options
Stay on SAP Enterprise Support
Continue paying SAP's 22% annual rate. Extended support surcharges apply from 2028. Migration pressure intensifies at each renewal. No cost reduction, ongoing vendor dependency.
Migrate to SAP Integration Suite
SAP's preferred path. 18–36 months for large landscapes, B2B partner re-certification, volume-based subscription pricing, and full interface redevelopment. High cost, high risk in the near term.
Replace with Third-Party iPaaS
MuleSoft, Boomi, or Informatica as alternatives. Technically viable but equally disruptive — every interface must be redeveloped in the new platform's framework. 2–5 year programme for large estates.

Check Your Exit WindowCommon Questions
Can GoVendorFree support PI/PO environments running on SAP HANA databases?
Yes. PI/PO 7.5 running on SAP HANA is the most common current production configuration. Our engineers cover both the PI/PO application layer and the underlying HANA database, including HANA tuning for the PI/PO message store workload pattern and HANA OS upgrade compatibility validation.
What about custom Java mappings and user-developed adapter modules?
Custom Java content is extremely common in PI/PO environments. GoVendorFree provides break-fix support for custom mappings and adapter modules — we diagnose failures, identify root causes, and provide remediation guidance. We do not undertake new development but can advise on code fixes for existing custom objects.
Does third-party support cover the B2B Add-on for EDI processing?
Yes. The SAP B2B Add-on (formerly B2B Connectivity Add-on) for PI/PO is within our standard coverage scope. This includes EDI converter configurations, agreement management, partner profiles, and end-to-end EDIFACT and ANSI X12 message flow troubleshooting.
How does GoVendorFree handle SAP SAP Notes that are released after we exit Enterprise Support?
We monitor SAP's published Note database and security advisory channels. Where SAP releases a Note relevant to your PI/PO version and configuration, we assess its applicability and assist with implementation. For security-critical Notes where SAP no longer provides fixes for your version, we provide compensating controls analysis and hardening guidance.
