What is a key requirement for the last two columns in the input worksheet?

The correct answer highlights that the last two columns in the input worksheet must contain a date followed by a quantity or money. This requirement is essential because it establishes the basis for how data will be interpreted and utilized within the system. The date component is critical for time-based forecasting and planning, as it helps to align the data with specific periods for analysis and decision-making. The quantity or monetary value is equally important because it quantifies what is being analyzed or forecasted, such as sales volumes or inventory levels.

Without a proper date and corresponding value, the data might not be actionable or could lead to misinterpretations in analyses, such as revenue projections or resource allocation. This structured approach ensures that the data input aligns with the expected format, allowing the system to perform calculations, generate forecasts, and present insights effectively.
