No company uses SAP alone. Every organization has an ecosystem of systems: a CRM to manage customers, a manufacturing system to govern factory operations, an e-commerce platform for online sales, collaboration tools, HR systems, industry-specific applications. Integrating these systems with SAP is one of the most frequent and most critical IT challenges for Italian companies.
In this article we explain key strategies for integrating SAP with the rest of the enterprise infrastructure, available tools, and best practices for ensuring effective, secure, and maintainable connectivity over time.
Why SAP systems integration is critical
When SAP is not integrated with other systems, information travels on parallel channels: manual exports, Excel files, periodic reconciliations. This creates delays, errors, and limited visibility into data. Decisions are made with incomplete or out-of-date information. Processes involving multiple systems require manual intervention, increasing time and the risk of errors.
Well-designed integration, on the other hand, allows data to flow automatically between systems, processes to coordinate without human intervention, and information to be up-to-date and consistent at all times. This is one of the key prerequisites of digital transformation with SAP.
The main approaches to SAP integration
Point-to-point integration: each system is connected directly to SAP through dedicated interfaces. This is the simplest approach for a few integrations, but it quickly becomes unmanageable as the number of systems to be connected increases.
Middleware (integration bus): an intermediate layer manages all data flows between systems. SAP Integration Suite (part of SAP BTP) is the SAP solution for this approach: it centralizes integration management, provides monitoring and ensures consistency.
API management: SAP services are exposed as APIs that other systems can consume. This is the most modern approach, suitable for cloud ecosystems and integrations with external systems or business partners.
SAP BTP as an integration hub
SAP Business Technology Platform has become the tool of choice for integrations with SAP. SAP Integration Suite, the dedicated BTP integration component, offers pre-built connectors for popular systems, flow monitoring tools, error management, and a secure environment for cloud-to-cloud and cloud-to-on-premise integrations.
The advantages over custom integrations are significant: less development from scratch, upgrades managed by SAP, guaranteed support, and a platform that follows the evolution of the technology landscape without requiring rewrites of integrations with each SAP upgrade.
Best practices for integrating SAP with other systems
- Document before integrating: clearly define what data should flow between systems, in which direction, how often, and with what priority
- Choose the right level of real-time: not all integrations require real-time updates; some nightly batches are sufficient and less expensive to manage
- Govern integrations as assets: document each integration, define clear ownership, and include integrations in IT change management processes
- Plan for error management: any integration can fail; having clear procedures for error management and data recovery is essential
- Continuously monitor: an integration that is not monitored silently becomes a problem: lost data, stopped processing, misaligned systems
