What happens if a user does not have access to a compatible filter for a variable used in worksheet filters?

When a user does not have access to a compatible filter for a variable used in worksheet filters, they cannot view any data in the workbook. This is because the absence of the necessary filter means that there is no way for the system to determine which data should be displayed to the user, thereby preventing any data from being visible. The filter is crucial for enabling the user to interact with the data effectively, since it controls the scope of information that can be accessed. Without the appropriate filter permissions, the entire workbook remains inaccessible from the user's perspective. This scenario emphasizes the significance of having the required filter access to obtain meaningful data from the workbook.
