Custom Reports with OData
Use the OData service to build custom reports and other interfaces based on SmartObject data. Create custom reports using workflow reporting data and data stored in a line of business system from SmartObjects created for those systems.
Exposing SmartObject data through the SmartObject OData API provides you with the ability to use data with third party tools like Excel and Power BI.
