Tip: Report commands/actions don't work in design/preview mode
I was working on a report and for some reason, my report commands/actions (e.g. Open, Delete) weren't working. Reporting guru anash informed me that report commands/actions do not work in preview or edit mode. They only work when you generate or open the report.
She also mentioned this question comes up a lot, so I thought I'd take a minute to share this tip with all of you.
