Disconnected tables are stand-alone tables in Power BI that do not have a direct relationship with the main model. Despite not having relationships, they serve an important role in advanced report capabilities, as they can work with things like parameter selection, dynamic measures and user-customized slicers. Disconnected tables can be used directly, or be used indirectly with DAX functions like SELECTEDVALUE, SWITCH or USERELATIONSHIP to control what's presented visually or toggle between different measures and manage other scenarios where you want manual control over calculations, etc. and disconnected tables model in a much cleaner and flexible way when devising reports involving detail from a complex data environment.
The Power BI Course in Pune covers basic modeling techniques around disconnected tables. It leaves participants understanding incrementally when disconnected tables should be employed and why to take their dashboards to the next level of interactivity and control logic without over-complicating the interdependence of tables and relationships.
Power BI Training in Pune for advanced users highlights how disconnected tables are used practically, and in applications such as KPI toggles, what-if scenarios or performance benchmarking, etc. They will have opportunities to customize user-driven reports through practice and takeaways, significance and precision. If you can leverage disconnected tables correctly, they can absolutely add tremendous increases in analytical functionality, and bespoke features and are therefore very productive to Power BI dashboards.
