Which function allows for scenario analysis to evaluate potential business impacts?

The function that facilitates scenario analysis to evaluate potential business impacts is the "What-if Plan." This feature allows users to create different scenarios by modifying variables, such as revenue, expenses, or other key performance indicators. By manipulating these variables, users can assess the potential outcomes of various business decisions and strategies.

The ability to perform what-if analyses is crucial in planning and forecasting, as it enables organizations to anticipate the effects of changes in the business environment and make more informed decisions. This function helps businesses prepare for uncertainties by projecting potential future states based on different assumptions, thus guiding strategic planning and risk management efforts.

Other options, while relevant in different contexts, do not serve the same purpose. For example, Subversion is not a recognized function in scenario planning, Virtual Version refers more to a representation of a model in a specific context rather than analysis, and Rollup typically refers to consolidating data from lower levels to higher levels rather than assessing different scenario outcomes.
