What does the "What-If" parameter allow users to do in Power BI?

The "What-If" parameter in Power BI empowers users to simulate different scenarios by altering variable values and observing the resulting outcomes. This functionality is particularly valuable for decision-makers who need to understand the potential impacts of varying assumptions or conditions, such as changes in sales price, unit costs, or market demand.

By using the "What-If" parameter, users can create dynamic reports that allow them to adjust these input values interactively. As users change the parameters, the visuals and calculations in the report update automatically to reflect the new data inputs, thereby providing insights into how different scenarios could potentially affect the overall analysis or business projections.

This capability enhances strategic planning, enabling users to evaluate risks and make informed decisions based on a range of possible future states. This is distinct from other options, such as visualizing historical data trends, which focuses on past performance rather than future scenarios, or automatically generating reports, which emphasizes report creation rather than interactive scenario analysis. The option to limit datasets based on input criteria also does not capture the full breadth of the "What-If" analysis, which is centered on scenario simulation rather than merely filtering data.
