What is the primary function of a quantity variable?

The primary function of a quantity variable is to limit data in worksheet filter expressions. In a data analysis context, quantity variables play a crucial role in defining specific criteria that can refine or filter datasets based on certain numerical thresholds. For instance, filtering a report to show only items with quantities greater than a specified number allows users to focus on relevant data and derive insights from more targeted information.

This is particularly important in supply chain and inventory management, where understanding quantities can influence planning and decision-making. By applying filters based on quantity variables, users can effectively manage data visibility and concentrate on critical aspects of their analysis, thereby enhancing the overall usability of the data presented in a worksheet.

In contrast, the other choices relate to distinct functionalities that do not primarily define the role of a quantity variable in data management or analysis contexts.
