SAP Integration Services
SAP integration connects your SAP core to the rest of the estate — other SAP systems, Salesforce, banks and logistics partners — through middleware rather than point-to-point code. Appsierra's senior SAP consultants build and operate Cloud Integration iFlows, API Management, and B2B/EDI exchanges on SAP Integration Suite, then prove each interface end to end before it carries a live transaction.
SAP integration is the layer that decides whether an ERP programme behaves as one system or a collection of silos. Appsierra's SAP integration consultants work on SAP Integration Suite — the integration capability of SAP BTP — building and operating Cloud Integration (CPI) iFlows for application-to-application flows, API Management for the services you expose and consume, and B2B/EDI exchanges with suppliers, banks and logistics partners. This is the middleware and interface layer specifically, not the wider BTP platform: our job here is the connections between systems, and keeping them correct.
On S/4HANA most integration moves off bespoke point-to-point code and onto governed iFlows, APIs and events — and SAP's older on-premise Process Integration/Process Orchestration (PI/PO) is on a path toward Integration Suite rather than long-term investment. We design to that model, reuse SAP's pre-packaged integration content where it fits (S/4HANA to SuccessFactors, Ariba, Concur and the like), and prove every interface through our system integration testing so the contract between two systems is verified rather than assumed.
Integration fails at the edges — a malformed IDoc, an expired certificate, a partner who changes their EDIFACT envelope without warning. We build the error handling, retry logic and monitoring that catch those before finance does, add event-driven flows through Event Mesh and Advanced Event Mesh where a system should react to a business event rather than poll for it, and harden the APIs themselves with our API testing services.
What the pod delivers
Cloud Integration (CPI)
Integration flows for application-to-application scenarios — mapping, routing, content enrichment and the adapters that connect SAP and non-SAP endpoints.
API Management
Designing, publishing, securing and versioning APIs — rate limits, OAuth, key management and a developer portal — so consumers use a stable contract, not a changing backend.
B2B / EDI
IDoc, EDIFACT and ANSI X12 exchanges modelled in Trading Partner Management, so onboarding a supplier, bank or carrier is configuration rather than a code change.
Event-driven integration
Event Mesh and Advanced Event Mesh so S/4HANA business events trigger downstream processing in near real time, instead of batch jobs polling for change.
How the engagement runs
Four steps from first call to a pod that is measurably working. You are never more than two weeks from evidence.
The stack we work in
We adopt your tools rather than imposing ours. These are the ones our engineers are already senior in.
What our SAP integration consultants build
Across the middleware and interface layer, by the flow the data takes rather than by the tool it runs on.
Cloud Integration (CPI) iFlows
Application-to-application integration flows with mapping, routing and enrichment, built on the adapters that reach both SAP and non-SAP endpoints.
API Management
APIs designed, published, secured and versioned — OAuth, rate limits, key management and a developer portal — so consumers code against a stable contract.
B2B / EDI & Trading Partner Management
IDoc, EDIFACT and X12 exchanges with suppliers, banks and carriers, modelled so a new partner is onboarded as configuration, not a release.
Event-driven integration
Event Mesh and Advanced Event Mesh so a business event in S/4HANA triggers downstream work in near real time, rather than a nightly batch polling for change.
Pre-packaged integration content
Reusing SAP's shipped integration packages for S/4HANA, SuccessFactors, Ariba and Concur, adapted to your data rather than rebuilt from scratch.
SAP-to-non-SAP connectivity
Governed, monitored links to Salesforce, banking networks, logistics providers and legacy systems, with credentials and certificates managed rather than hard-coded.
How an SAP integration engagement runs
An interface is low-drama only when the unhappy path is designed before, not after, it carries live data.
Map the interface landscape
We inventory every interface — source, target, volume, frequency and failure impact — before building, so the design matches what actually flows.
Build on governed middleware
iFlows and APIs are built, versioned and transported like code, with no undocumented point-to-point connections quietly added in production.
Handle the unhappy path
Error handling, dead-letter queues, retries and alerting are part of the build, because an interface is judged on how it fails, not how it succeeds.
Prove then monitor
Each interface is tested end to end against the receiving system, then watched in production so a broken partner feed is found by a dashboard, not a missing payment.
Why integration leaders choose Appsierra for SAP integration
Senior-led, accountable
A senior integration consultant owns the design, so the interface architecture you approve is the one that ships — not a hand-off to an unseen team.
Build and test in one pod
The pod that builds the iFlows and APIs also tests them, through our QA and integration-testing practice, so interfaces are proven rather than assumed to work.
Honest on the boundary
We integrate and harden your interfaces; we do not own your partners' systems or SAP's cloud service levels, and we say plainly where each party's responsibility ends.
