Correction: This blog as earlier stated not using OData, instead we are using to access the HANA catalog tables created by the SAP River program.
RIVER code when activated creates tables and oData for the entity. The table created by RIVER code will be used to get the data from SAP HANA into SAP Lumira for preparing dataset. This dataset will be used for Visualization.
Only SAP HANA Analytic Views can be used in SAP Lumira for preparing datasets.
In this blog we will use HANA tables created by SAP RIVER in SAP Lumira for preparing data sets.
