In which scenarios might a profile variable or macro be used instead of workbook variables?

Using a profile variable or macro is particularly advantageous for creating universal expressions that can function across multiple worksheets. This approach allows for greater flexibility and efficiency when building models that require consistency and reusability of calculations or conditions throughout different parts of the workbook. Profile variables and macros are designed to be accessed and utilized across various worksheets, making them ideal for scenarios where a user needs to implement the same logic or expression in multiple locations without having to rewrite or copy variables individually for each worksheet.

This capability enhances the maintainability of the workbook, as any updates to the profile variable or macro can be made in a single location rather than needing to modify numerous individual variables across worksheets. It also promotes best practices in model building by encouraging the use of shared resources that can streamline workflows and reduce the risk of inconsistencies or errors that can arise from manually managing multiple variables independently.
