What is Open ODS views?

Open ODS views in SAP BW/4HANA are used to integrate data from various sources without physically storing the data within BW. They act as virtual data models that define how external data should be accessed and interpreted within the BW environment. They are commonly used to combine data from data lakes, operational data stores, or other external systems with data already in the BW system, allowing for a consolidated view for reporting and analysis.
