How can you check the layout of your Flex Data report before you save or run the report?

To check the layout of your Flex Data report before saving or running it, you can use the "Preview" option available in the report design interface. This allows you to see how the report will look with sample data, ensuring that formatting, alignment, and overall presentation meet your expectations. Additionally, you can adjust the layout in real-time based on the preview feedback. Always review key elements like headers, footers, and any conditional formatting to ensure accuracy.
