Which feature allows you to change filtering operations in a workbook after it has been saved?

The feature that allows you to change filtering operations in a workbook after it has been saved is related to Workbook Filtering Operations. This functionality enables users to modify how data is filtered within the workbook, giving them the flexibility to explore different views of the data without needing to recreate or significantly alter the underlying data structure.

This capability is particularly useful in scenarios where users need to analyze data from various perspectives or adapt their analysis based on new insights or specific queries that arise after the initial data presentation. It facilitates a dynamic interaction with the data, enhancing the analytical process.

In contrast, the other options do not specifically refer to the ability to alter filtering operations in an already saved workbook. Data Modification Commands focus more on changing the data itself, Composite Worksheets deal with combining multiple data sources, and Flexible Filtering refers to the adaptability of filters but does not explicitly emphasize the operational aspect related to already saved workbooks. Thus, Workbook Filtering Operations is the most appropriate feature for changing filtering settings after saving the workbook.
