I frequently prepare Budget vs. Actual reports for clients. I set up the basics and then click the Customization tab for additional settings. For my nonprofit clients in particular, I usually select the "Fiscal Year to Last Month" setting. If I choose this under Customization, it does not correctly update the dates on the actual report. It defaults to the entire year. I have to take another step to correct the dates. I've ended up sending incorrect totals to clients on more than one occasion before I figured out what was happening.
