Which function requires two or three worksheets based on the data used?

The project override function requires two or three worksheets based on the data used because it involves managing and integrating various project parameters and scenarios that may derive from different sources. This function allows users to modify specific project details or assumptions, which necessitates the use of multiple data sets for comprehensive analysis. These worksheets generally include information such as project plans, resource allocations, and historical performance data to effectively analyze and adjust the project's course.

This complexity and the need for different data perspectives is what makes this function unique, as it relies on synthesizing information from these various worksheets to provide meaningful insights and adjustments for effective project execution.
