SAP S/4HANA Metadata Explorer

CDSee

Explore the complete SAP S/4HANA data model — from CDS Views down to field-level lineage.

Features

What is CDSee?

CDSee is the largest independent SAP S/4HANA metadata explorer. It provides structured, searchable access to CDS Views, DDIC Tables, OData Services, Fiori Apps, Joule AI Capabilities, and Field Mappings across three SAP S/4HANA editions: Private Cloud (RISE), Public Cloud (GROW), and On-Premise.

SAP developers, consultants, and data engineers use CDSee to explore the SAP S/4HANA data model without needing direct access to a running SAP system. Every CDS View includes its schema representation, field definitions with source table mappings, VDM classification, annotations, and OData service exposures.

Key Capabilities

  • Field-Level Data Lineage — Trace any field from a physical database table through chains of CDS Views to understand exactly where data comes from and how it transforms.
  • 3D Dependency Graphs — Visualize CDS View dependencies as interactive 3D force-directed graphs and ER diagrams.
  • S/4HANA Migration Planning — Check which ECC tables have been replaced, merged, renamed, or deprecated in S/4HANA, with direct links to successor tables and CDS Views.
  • BW Extractor Mapping — Find CDS View replacements for 4,700+ BW DataSources based on SAP Note 2500202.
  • AI-Powered Chat — Ask questions about CDS Views, tables, and data models in natural language and get answers grounded in real system metadata.

Who Uses CDSee?

CDSee serves SAP professionals across different roles: ABAP developers exploring the Virtual Data Model (VDM) and building custom CDS Views, data engineers mapping data flows from SAP source systems, functional consultants understanding which Fiori Apps use which OData Services, and migration teams planning their transition from ECC to S/4HANA.

All data is extracted from real SAP S/4HANA systems and indexed for fast search. CDSee is free to use and requires no SAP login or license. Browse our developer guides to learn more about CDS Views, the VDM, OData Services, and S/4HANA migration patterns.
