Hi all, just spotted this. I don't think you can avoid empty reports being sent in Workfront but I did find a crude workaround (from someone else on community) to this issue that has worked for me in certain circumstances.
Given lots of people rely on their email notifications to prompt them to go into Workfront, I use the functionality within Outlook (i guess other email systems can do the same). The report is sent to a central email account which only forwards the email on to target users if there is an attachment present (as empty reports are sent with no attachment).
It doesn't stop the empty reports piling up within Workfront, but I've found it useful for reports which only populate when there's something to review and possibly a custom field to update, going to people that don't go into Workfront regularly. Using the repeat functionality I can also get the report to resend every few days until the custom field has been updated an the report is blank (due to the filters) as a reminder.
Hope that makes sense and may help you or others on this discussion.
Richard
