Clean integration structures form the backbone of modern SAP landscapes. They connect systems, control end-to-end processes, and guarantee operational reliability. As demands for transparency, flexibility and operational reliability increase, one thing is clear:
Integration must not become a bottleneck.
So, what do customers really expect from their integration landscape today?
Business-critical processes must run smoothly – regardless of system boundaries.
Errors, runtimes and dependencies must be traceable at all times.
New systems, partners or business models should be integrable – without large-scale projects.
Discontinuations such as SAP PI/PO must not pose an operational risk.
QUANTO Solutions supports customers in achieving this goal. The SAP Integration Suite serves as the technological basis for replacing existing PI/PO scenarios in a controlled manner and modernising integrations in a sustainable way.
For stable processes, clear control over interfaces and an integration landscape that enables change without burdening the SAP core.
The SAP Integration Suite is the central component for integration, API management and event communication within the SAP Business Technology Platform (BTP). Designed to connect heterogeneous system landscapes in a controlled manner, it can be used with systems operated on-premises or in the cloud, and with SAP and non-SAP applications.
Rather than providing isolated interface solutions, the Integration Suite offers a consistent integration structure that unifies various integration patterns, including synchronous APIs, asynchronous message processing, and event-driven communication.
The SAP Integration Suite serves as a technological enabler to:
replace existing PI/PO scenarios in a controlled and gradual manner,
anchor integration logic outside the SAP core,
increase the transparency, security and controllability of interfaces,
and create an integration architecture that already takes future requirements (APIs, events, cloud services) into account.
We provide structured support to companies, from analysing existing interfaces and carrying out a step-by-step migration, to ensuring a stable go-live and ongoing operation. Our goal is to create a future-proof, clean-core-compliant integration architecture that decouples S/4HANA in a sustainable manner, ensuring long-term operation. Against the backdrop of the imminent replacement of SAP PI/PO, the importance of this structured transition is increasing.
The integration logic is consistently anchored outside the SAP core. This creates a clear division of responsibilities between business logic, integration, and operations.
Impact: fewer error chains and fewer side effects when changes are made, as well as greater operational reliability, particularly during releases and upgrades.
A uniform integration layer replaces the point-to-point connections that have been established over time. Interfaces now follow defined patterns rather than individual special solutions.
Impact: Integrations become predictable in terms of effort, risk and time. Dependence on individual systems or people decreases measurably.
Additional partners, new front ends or cloud services can be connected via APIs and events, meaning that existing processes do not need to be rebuilt.
Impact: Changes are implemented additively, not invasively. This means that existing processes remain stable while new ones are added in a controlled manner.
Individual implementation and operating variants are replaced by reusable integration patterns, centralised, cross-system monitoring, and standardised error and exception handling.
Impact: Integrations become more robust, analysis and recovery times are reduced, and day-to-day operational effort is measurably reduced.
APIs and integration artefacts are centrally managed, versioned and controlled via consistent security and access mechanisms. Usage, changes and dependencies can be traced transparently.
Impact: Increased security, improved audit and compliance capabilities, and a robust basis for making decisions on architectural, operational and investment issues.
The architecture is designed with integration principles in mind, such as decoupling, standardisation and reusability, rather than for a single system or a temporary solution.
Impact: Technology changes, such as the transition from SAP PI/PO to SAP Integration Suite, can be planned for instead of being forced upon us.
