SAP Integration Suite Services
SAP Integration Suite is SAP's cloud-native integration platform — combining Cloud Integration (iFlows), API Management, Event Mesh, Open Connectors and Integration Advisor in one governed service on SAP BTP. It connects SAP S/4HANA, Business One and SuccessFactors to each other and to hundreds of third-party systems — replacing the on-premise SAP PI/PO middleware that many businesses are now being asked to migrate away from. 2iSolutions designs, builds and operates SAP Integration Suite deployments across new integration projects and PI/PO migrations.
What SAP Integration Suite delivers — six core capabilities
SAP Integration Suite is not a single integration tool — it is a platform combining several capabilities that work together. Understanding which capability applies to your integration scenario is the first step in scoping correctly.
Cloud Integration (iFlows)
The core integration runtime — where data flows (iFlows) are designed, deployed and executed. iFlows define how data moves between systems: what triggers the integration, how data is mapped and transformed, what adapters connect to each endpoint, and how errors are handled. Supports synchronous (real-time request/response) and asynchronous (event-triggered, batch) patterns.
API Management
Design, publish, secure and manage APIs exposed by SAP and non-SAP systems — through a governed API portal. API policies enforce authentication, rate limiting, caching and quota management. Internal and external developers discover and subscribe to APIs through the Developer Portal. Particularly important when SAP data needs to be exposed to partner systems or custom applications.
Event Mesh
Event-driven integration for real-time, decoupled message exchange — where a change event in one system is published to a topic and consumed by one or more subscribing systems asynchronously. Useful for high-volume scenarios (stock level changes, order status updates, payment confirmations) where tight coupling creates bottlenecks or cascading failure risk.
Open Connectors
170+ pre-built connectors to third-party SaaS applications — Salesforce, HubSpot, ServiceNow, Shopify, Marketo, Workday and more — normalised through a common API framework. Reduces the effort of integrating SAP with popular cloud applications by providing pre-configured connectivity rather than custom REST adapter development for each system.
Integration Advisor
B2B and EDI message standard library — covering EDIFACT, X12, TRADACOMS, HL7 and industry-specific standards. Generates mapping proposals between business documents and EDI message structures using machine learning. Particularly relevant for manufacturers and distributors exchanging purchase orders and ASNs with enterprise customers in EDI formats.
Integration Assessment
A structured analysis of your current integration landscape — cataloguing existing PI/PO interfaces, classifying them by complexity and traffic, and producing a migration roadmap for Cloud Integration. Identifies which interfaces can use standard adapters, which need custom iFlow development, and which should be retired rather than migrated.
Migrating from SAP PI / Process Orchestration to Cloud Integration
SAP has announced end of mainstream maintenance for SAP PI/PO. Businesses running their integration middleware on-premise are now planning the migration to SAP Integration Suite's Cloud Integration — and the migration is more than a technical lift-and-shift.
On-premise integration middleware
- Self-hosted — infrastructure, patching and OS management your responsibility
- Java-based runtime with XI protocol complexity
- Alert monitoring via SAP CCMS and RWB — limited observability
- Scaling requires hardware provisioning
- New SAP adapters and features rarely backported
- End of mainstream maintenance approaching
- High operational overhead for a middleware platform
Cloud-native, SAP-managed integration platform
- SAP-managed infrastructure — no OS or middleware patching
- Modern iFlow designer with graphical, browser-based editing
- Built-in monitoring dashboard with message tracing
- Elastic scaling — handles traffic spikes automatically
- New adapters, pre-packaged content and SAP AI features added continuously
- On SAP's current roadmap — actively developed
- Reduces integration team's operational overhead significantly
What migration actually involves
Interface Catalogue
Inventorying all PI/PO interfaces, classifying by protocol, traffic volume and business criticality.
Redesign, Not Copy
iFlows designed for Cloud Integration patterns — not XI protocol objects copied verbatim into the new system.
Parallel Run & Testing
Each interface migrated, tested in isolation and run in parallel with PI/PO before cutover — not all moved at once.
Phased Cutover
Interfaces cut over in waves by business criticality — low-risk batch interfaces first, critical real-time interfaces last.
Common SAP Integration Suite scenarios we implement
Every integration scenario has different timing requirements, data volume, error tolerance and transformation complexity. We assess each one before recommending the right iFlow pattern and adapter.
SAP S/4HANA ↔ Salesforce / CRM
Bidirectional customer and opportunity sync — accounts and contacts created in Salesforce replicated to S/4HANA customers; sales orders created in S/4HANA sent back to Salesforce for opportunity closure and pipeline visibility.
- Customer master replication (near real-time)
- Sales order status sync
- Invoice and payment status to CRM
- Open Connectors adapter for Salesforce
SAP S/4HANA ↔ Shopify / Magento
Orders placed on Shopify or Magento flow into S/4HANA as sales orders; inventory levels and price updates from S/4HANA pushed back to the storefront in near real-time to prevent overselling.
- Order-to-S/4HANA sales order creation
- Stock availability sync (scheduled or event-driven)
- Delivery confirmation and tracking to storefront
- Product master and price replication
SAP S/4HANA ↔ 3PL / Logistics Providers
Outbound delivery orders sent to third-party logistics providers; shipment confirmation, AWB numbers and tracking status received back into S/4HANA — closing the delivery loop in the ERP without manual re-entry.
- Delivery order dispatch to 3PL (EDI or API)
- ASN and shipment confirmation receipt
- Proof of delivery update to S/4HANA
- Return and exception handling
SAP S/4HANA ↔ Banking & Treasury
Bank statement auto-import from bank portals via SWIFT MT940/CAMT.053, payment file generation (NEFT/RTGS) from S/4HANA payment runs, and reconciliation confirmation from bank to clear open items automatically.
- Bank statement import (MT940, CAMT.053)
- Payment file dispatch to bank
- Advice note and reconciliation receipt
- Direct debit and collection integration
SAP S/4HANA ↔ GST / Government Portals
e-Invoice IRN generation from S/4HANA invoices via IRP (Invoice Registration Portal), e-way bill creation for qualifying dispatches, and GSTR data extraction — all driven from within S/4HANA without manual portal login.
- e-Invoice IRN generation (IRP API)
- QR code and signed invoice PDF
- e-Way bill generation and management
- GSTR filing data preparation and export
SAP S/4HANA ↔ SAP SuccessFactors
Employee data and organisational structure replicated from SuccessFactors to S/4HANA HR and payroll; cost centre and posting assignments maintained in sync; payroll results posted from S/4HANA back to SuccessFactors for employee statements.
- Employee master and org structure replication
- Cost centre assignment sync
- Payroll posting from S/4HANA to SF
- Standard SAP pre-packaged integration content

What makes our SAP Integration Suite practice different
BTP-First, Not Integration-Only
We implement Integration Suite as part of SAP BTP — alongside HANA Cloud, API Management and SAP Build. Integration Suite deployments are more effective when the broader BTP architecture is designed together, not added piecemeal. Our BTP practice covers the full platform.
PI/PO Migration Experience
We have executed on-premise SAP PI/PO to Cloud Integration migrations — not just new iFlow development. The interface catalogue, redesign-not-copy approach, parallel run and phased cutover methodology comes from real migration projects, not theory.
SAP + Non-SAP Depth
Integrations fail most often at the non-SAP end — the third-party system's API is underdocumented, the connector has limitations or the data model doesn't map cleanly. Our team understands both the SAP end and the common third-party systems (Salesforce, Shopify, logistics APIs, banking systems) in equal depth.
Indian Compliance Integrations
GST e-invoicing via IRP, e-way bill via NIC, GSTR data extraction, TDS and TCS handling — built into S/4HANA Integration Suite deployments for Indian businesses. These integrations have specific API contracts, certificate requirements and regulatory edge cases that generic integration patterns don't handle correctly.
Error Handling & Monitoring as First-Class Requirements
Integration flows that silently fail are more dangerous than those that visibly fail. We build error handling, retry logic, dead-letter queuing and monitoring dashboards into every iFlow as core requirements — not optional extras added when production incidents occur.
Integration AMS — Operations After Go-Live
Integration flows need ongoing management — adapters change, external APIs are updated, message volumes spike and new scenarios emerge. We operate Integration Suite environments under the same AMS practice that covers the SAP application layer — single contract, single point of contact, proactive monitoring rather than reactive incident response.
Integration Suite from a team that builds on the full SAP BTP platform
2iSolutions has built four production applications on SAP BTP — DealerConnect, ShopConnect, SupplierConnect and ServiceConnect — using Integration Suite and other BTP services. Our integration practice is built on real BTP development experience, not just iFlow configuration.
SAP Integration Suite: frequently asked questions
What is SAP Integration Suite and how does it relate to SAP BTP?
SAP Integration Suite is one of the core services on SAP Business Technology Platform (BTP) — specifically the integration and API management service. It combines Cloud Integration (the iFlow runtime), API Management, Event Mesh, Open Connectors, Integration Advisor and Integration Assessment into one subscription. It runs on SAP BTP's hyperscaler infrastructure, managed by SAP, with no middleware servers for the customer to maintain.
Should our business migrate from SAP PI/PO to SAP Integration Suite?
SAP has announced end of mainstream maintenance for SAP PI/PO, making migration a question of when rather than whether for most businesses. The stronger case for migrating sooner is operational: Cloud Integration eliminates on-premise middleware maintenance, provides better monitoring and observability, scales automatically and receives new adapters and features that won't be backported to PI/PO. The migration also provides an opportunity to redesign interfaces that have accumulated technical debt over years of patching.
What is an iFlow and how are integrations built in SAP Integration Suite?
An iFlow (integration flow) is the configuration artefact that defines how data moves between two systems in SAP Cloud Integration — what triggers it (a message, a schedule or an API call), how data is mapped and transformed between source and target formats, which adapters connect to each system, and how errors are handled. iFlows are designed graphically in the Cloud Integration Web IDE and deployed to the managed integration runtime on BTP.
How does SAP Integration Suite handle errors and message failures?
Cloud Integration has built-in message monitoring where every message processed can be inspected — its status (completed, failed, retry), payload and processing log. We design every iFlow with explicit error handling: retry logic for transient failures (network timeouts, target system unavailable), dead-letter handling for messages that exhaust retries, and alerting to nominated recipients when failures occur. Integration flows with no error handling are a liability; ours are built for production reliability from the start.
Can SAP Integration Suite connect to non-SAP systems?
Yes — this is one of its primary uses. SAP Integration Suite ships with adapters for HTTP, REST, SOAP, OData, SFTP, JDBC, RFC, SuccessFactors, Salesforce, and many others. The Open Connectors service adds 170+ pre-built connectors to popular SaaS applications. For systems without a native adapter, the HTTP or REST adapter covers any system with an API. For legacy systems, SFTP-based file exchange is supported as a lowest-common-denominator integration pattern.
How long does a SAP Integration Suite implementation take?
A single, well-scoped integration (e.g., S/4HANA to Salesforce account sync) typically takes 4–8 weeks — requirements, iFlow design, adapter configuration, mapping, testing and go-live. A PI/PO migration covering 20–50 interfaces typically takes 3–6 months depending on interface complexity, the number of legacy XI protocol objects and the parallel run period required before PI/PO can be decommissioned. We scope per interface at the outset rather than providing a blanket estimate.
Building a new SAP integration or planning a PI/PO migration?
Whether you need a single new integration between S/4HANA and a third-party system, or a full PI/PO to Cloud Integration migration programme, a conversation about your specific landscape is the right starting point.
