Adding Power ON to Birds and Power BI generates a “Two Way Street”, which essentially enables companies to provide and collect information from end-users.
This allows PowerBI users to enhance their insights into data beyond a static dashboard with a drill down. With Power ON you can add comments, rich meta data, make predictions or change assumptions. You simply update budgets in Power BI and Power ON recalculates the whole column based on the new budget, even with seasonal influence(s) and weighted averages.
