Open Hub
Open Hub Destination (OHD) is the SAP BW/BW4HANA mechanism for extracting data out of BW InfoProviders into non-BW targets such as flat files, database tables, or third-party applications via APIs, enabling controlled, delta-capable data distribution for downstream analytics, data lakes, and integration scenarios.
Overview
Open Hub Destination (OHD) is the SAP BW/BW4HANA mechanism for extracting data out of BW InfoProviders into non-BW targets such as flat files, database tables, or third-party applications via APIs, enabling controlled, delta-capable data distribution for downstream analytics, data lakes, and integration scenarios.
Lessons in this topic
- SAP Open Hub Tutorial (Part 1)Understand why Open Hub Destinations exist in SAP BW, what business and technical problems they solve, and the basic building blocks involved in distributing data outside the BW system.
- Configuring Open Hub Destinations and DTP-Based Extraction (Part 2)Learn the practical steps and design decisions for configuring an Open Hub Destination, defining field mappings, choosing delta settings, and wiring the extraction DTP into a process chain.
- Managing Delta Loads and Change Data Capture in Open Hub Destinations (Part 3)Learn how Open Hub Destinations track delta changes, how DTP delta modes interact with OHD request status, and how to design robust incremental extraction for downstream consumers without duplicate or missing records.
- Advanced Open Hub: Architecture, Integration and Production Design (Part 4)Advanced capstone for Open Hub, connecting the existing lesson areas: Open Hub Fundamentals: Purpose and Core Concepts; Configuring Open Hub Destinations and DTP-Based Extraction; Managing Delta Loads and Change Data Capture in Open Hub Destinations. The goal is to move from feature knowledge to architecture, integration, production support and governance decisions.
Interview questions covered
- What are the core concepts of Open Hub, and how would you explain them clearly in an SAP interview?
- How would you apply Open Hub in a real SAP project? Walk through the design or implementation approach.
- A production issue is reported in Open Hub. What would you check first, and how would you troubleshoot it systematically?
- What are the most important design decisions, trade-offs, and best practices in Open Hub?
- Suppose you inherit an existing Open Hub solution. How would you review it before making a change?
- A senior architect is reviewing Open Hub. The project situation is: A retail company's finance team built their consolidated reporting in BW/4HANA but needed daily extracts of reconciled GL balances pushed into a corporate data lake used by a separate analytics team running Python-based forecasting models. What design changes, validation evidence and production controls would you require before approving the solution?
- A project encounters this situation while working on Configuring Open Hub Destinations and DTP-Based Extraction: A manufacturing company needed to feed a legacy MES-adjacent reporting tool with daily production variance data. Walk through how you would analyze the requirement or issue, what you would validate, and how you would test the solution before release.
- Using this SAP project situation — A retail company's finance team built their consolidated reporting in BW/4HANA but needed daily extracts of reconciled GL balances pushed into a corporate data lake used by a separate analytics team running Python-based forecasting models — explain Open Hub Fundamentals: Purpose and Core Concepts. What should happen, which concepts or process steps matter, and what common mistake would you avoid?
- A project encounters this situation while working on Managing Delta Loads and Change Data Capture in Open Hub Destinations: A retail analytics team used an Open Hub Destination on a sales InfoCube to feed a downstream cloud data lake nightly via a database table destination and a custom pickup job. Walk through how you would analyze the requirement or issue, what you would validate, and how you would test the solution before release.
