When the OData (Open Data Protocol) feature for your BlueDolphin tenant has been activated, it will be possible to get the data from BlueDolphin into any reporting product that can source data from an OData feed and support basic authentication. The examples are Microsoft Power BI and Microsoft Excel.
Note: Currently, the BlueDolphin repository data that is available through OData is limited to objects, relationships, object questionnaires, and relationship questionnaires. Also, please note that relationship questionnaires are not yet available in history.
In this article, we will demonstrate the use of OData in Microsoft Power BI Desktop.
