The new SAP API Policy: What the restrictions mean and what alternatives remain

With API Policy v4/2026 (April 2026), SAP makes it unmistakably clear that the ERP core will be more strongly protected in the future. Uncontrolled mass data extraction into external data lakes or BI tools via standard APIs is increasingly reaching its limits. Organizations that rely heavily on continuously repeated OData calls or poorly documented endpoints in their data architecture must prepare for new rate limits and governance requirements.

This move by SAP is embedded in a clear strategy. Under the guiding principle of the “Clean Core,” a historically grown sprawl of unregulated interfaces is to be structured. The objective is to create a system that is maintainable and upgrade-ready, whose performance is not unnecessarily burdened by countless resource-intensive accesses. For IT managers and internal auditors, this regulation is a positive development – it enables real governance in complex system landscapes.

However, for data engineers and BI stakeholders in the field of SAP data integration, the new SAP API Policy requires a careful architectural realignment.

Why traditional SAP APIs are reaching their limits

The challenge with many data pipelines lies in their architecture: standard SAP APIs (such as OData or REST) are primarily designed for event-based transactions or fine-grained queries. However, when these SAP interfaces are used for continuous replication of large data volumes, they quickly exceed their architectural limitations.

SAP is now responding with defined limits, quotas, and clearer guidelines for automated workloads. This also affects modern cloud and AI scenarios that systematically replicate ERP content. Architectures that still rely exclusively on such endpoints for mass data today are increasingly colliding with SAP’s official roadmap.

The new SAP API Policy v4/2026 is therefore not just a technical adjustment, but above all a governance signal: SAP APIs and SAP interfaces are expected to be used in a more controlled, standardized, and well-documented manner in the future.

RFC remains a stable access path for mass data

However, the regulation of APIs does not mark the end of data-driven business management. The solution lies in relying on established architectural components designed for handling large data volumes: Remote Function Call (RFC).

While API interfaces are becoming more strictly regulated under the current policy, RFC remains intact as a native communication mechanism within the SAP architecture. For data-intensive analytics scenarios, RFC continues to act as a high-performance and reliable data bridge into SAP business logic.

RFC offers several advantages, particularly for modern SAP data integration:

• High-performance access to large data volumes
• No dependency on API limits
• Stable integration into existing SAP system landscapes
• A robust long-term architecture for analytics and data lake scenarios

RFC enables efficient read access to exactly the data volumes required by modern data lakes—without being constrained by the HTTP-based limitations of traditional SAP interfaces.

SAP Clean Core as the foundation for future-proof architecture

The new SAP API Policy clearly demonstrates that in the long term, it is not individual SAP interfaces that matter most, but the overall architectural strategy.

Companies need integration solutions that remain upgradeable, do not require inadmissible core modifications, and operate in compliance with SAP standards. This is where the Clean Core approach becomes a strategic factor. Organizations that early adopt Clean Core-compliant integration architectures reduce risks and create long-term investment security.

dab Nexus: A resilient alternative to API restrictions

With dab Nexus, companies free themselves from restrictive API limitations. The software bypasses bottlenecks in ODP replication APIs by directly leveraging certified RFC interfaces within the SAP system. The resulting data extraction is “Clean Core Level B” certified, preventing compliance conflicts from the outset.

The outcome is a data infrastructure that remains stable even as future ERP governance requirements evolve. It enables organizations to securely and efficiently provide extracted data to external environments for modern AI use cases – without directly interfering with the SAP system.

SAP APIs: Essential interfaces, but not for every scenario

Robust data architectures are defined by their ability to seamlessly adapt to changing vendor requirements. In light of emerging limitations, it is advisable to review existing data pipelines early on for dependencies on APIs that are not available in the Business Accelerator Hub, in order to prevent disruptions in analytics operations.

A key success factor is selecting the right tool in alignment with Clean Core principles. Especially for high-volume data lake, BI, and analytics projects, RFC-based access remains the most technologically stable and future-proof option – even in modern SAP environments.

Q&A about SAP API Policy

What impact does the new SAP API Policy have?

The policy particularly imposes stricter limitations on non-published APIs, automated API usage, and large-scale data extraction. Companies should therefore review existing integrations for governance and compliance risks.

What is the difference between SAP API and RFC?

SAP APIs are published programming interfaces with clearly defined rules and limits. RFC, on the other hand, is a native SAP communication mechanism for accessing SAP function modules.

Are RFC interfaces affected by the SAP API Policy?

No. RFC is part of the native SAP architecture and is not directly subject to API regulations.

What is the best alternative to SAP API interfaces?

For data-intensive analytics and integration scenarios, RFC-based and Clean Core-compliant architectures are considered particularly future-proof.

As a dab customer, am I affected by the API policy?

No. dab Nexus does not use ODP replication APIs and relies on an SAP-certified RFC-based access path. This means there is no direct dependency on API limits or API restrictions.
