    IFRS S2 + NIS B-1 for Family Business with SAP S/4HANA: Data Integration 2026

    BMV and BIVA issuers face the unique challenge of simultaneously complying with IFRS S2 (CNBV) and NIS B-1 (CINIF) for the same fiscal year, implying two regulatory frameworks, two regulators, and potentially two external assurance processes. Without a centralized platform, companies end up with sustainability and finance teams operating in silos, collecting redundant data in non-auditable spreadsheets. The overlap between IBSO indicators and IFRS S2 metrics is significant but not total, requiring precise mapping.

    Climatta connects to SAP S/4HANA via standard OData APIs and extraction from SAP Analytics Cloud, with no agents installed on the client's system. Data from PM, EHS, and FI-CO is automatically mapped to the 30 IBSO indicators and IFRS S2 metrics, eliminating manual transcription that invalidates assurance. End-to-end traceability from the SAP source system to the audited report is the central argument for the assurer in 2027.

    Data Already in Your SAP S/4HANA

    Your SAP S/4HANA already has most of the data IFRS S2 + NIS B-1 requires. Climatta extracts it automatically without manual work.

    Energy consumption by plant and cost center from PM and FI-CO modules with hourly granularity

    GHG Scope 1 emissions directly from EHS module with configurable emission factors per facility

    Industrial waste generation and disposal data from PM with traceability by manifest

    Water consumption by process and production line integrated from IoT-connected meters to SAP

    Why Excel from SAP S/4HANA Will Not Pass the 2027 Assurance

    Integration complexity: High

    No audit trail: the auditor cannot trace the data back to its source in SAP S/4HANA

    Formula error risk: one miscalculated cell invalidates the entire report

    No change history: impossible to demonstrate data integrity over time

    SAP S/4HANA → Excel → report = 3 manual transformations with no governance control
